Dejia Liu PhD Candidate, NIFE, University of Veterinary Medicine Hannover

In this presentation, we show how numerical simulations can be used to study cooling dynamics of droplets exposed to solid surface vitrification (SSV) or solid surface freezing (SSF). Furthermore, we have investigated cryosurvival of droplets of human red blood cells exposed to conditions resulting in either SSV or SSF.

He studied mechanical engineering at the Leibniz University Hannover and is now conducting his PhD studies at the University of Veterinary Medicine Hannover in the Biostabilization group of Dr. Wolkers where he investigates membrane and tissue transport processes during cryopreservation of reproductive cells and tissues.


Charles Elder Graduate Research Assistant, University of Louisville

The desiccation of transfusable red blood cells (RBCs) for long-term ambient storage has been an objective of scientists for decades. Unfortunately, problems such as hemolysis and hemoglobin oxidation are commonly observed after rehydration of dry-preserved cells. Our lab has developed an assay to quantify the effectiveness of lyoprotectants and determine their proficiency at inhibiting hemoglobin oxidation during drying and rehydration. Utilizing this assay, we have investigated the properties of lyoprotectants that provide these molecules with the capacity to inhibit hemoglobin autooxidation. We aim to develop novel formulations of lyoprotectants with high intracellular delivery into RBCs to prevent desiccation-induced hemoglobin oxidation.

Charles A. Elder was born in Louisville, Kentucky, USA. He attended the University of Louisville for his undergraduate and graduate career, receiving a Bachelor of Arts in Biology and Psychology and a Master of Science in Biology. Charles is pursuing his Ph.D. in molecular biology at the University of Louisville. He has published two first-authored papers in his early career and is the Vice-President of the International Cryobiology Young Researchers organization.


Lakshya Gangwar PhD Candidate, University of Minnesota, USA

Convective cooling approach works well for smaller systems, it can be a challenge for larger systems, both in i) achieving rapid cooling throughout the volume to avoid ice formation and ii) sufficiently uniform cooling to avoid thermal stresses that can lead to cracking. So far, successful vitrification and rewarming has been demonstrated in models such as rabbit kidneys and rat hearts, kidneys and livers, heart valves where total preserved volume is 10-90mL. To extend these results to scale of human organs this presentation will demonstrate physical success of vitrification & nanowarming as well modeling predictions for various human organs.

I am a graduate student researching organ cryopreservation, large-scale vitrification, and computational modeling. Trained as a mechanical engineer from IIT Kanpur, India I graduated with an academic excellence award. In my senior year, I earned a DAAD WISE scholarship for summer research at Leibniz University, Hanover. I have volunteered for non-profits like Science for All (UMN) and National Service Scheme (India). Currently, I volunteer for ICYR and Scholarship Leadership Council at NSF-ERC ATP-Bio.

A Brief History of Cryoablation and the Technology Behind It
In this presentation, an overview will be provided on the history of cryoablation with a specific lens on oncologic applications.  The science and technology enabling cryoablation will be reviewed as well as the mechanisms of action from cryoablation driving therapeutic effects.  Finally, a look to the future of cryoablation and clinical applications will be discussed.

Biography: Dr. Chad Eckert is currently a Senior Principal Engineer within Interventional Oncology at Johnson & Johnson, driving scientific activities around device and procedure development for intratumoral therapy.  Prior to this role, Chad worked at Ethicon (Johnson & Johnson), leading front end R&D projects and preclinical model development. Following the completion of a B.S. degree (Materials Engineering) and a PhD (Bioengineering) from the University of Pittsburgh, he worked at UPMC as an engineer in the Artificial Heart Program. 


Speaker: Ms. Minhan Jiang PhD candidate, University of Minnesota, USA

Harnessing the Immunomodulatory Effect of Cryoablation for Cancer Treatment
Cryoablation has been a longstanding method for treating solid tumors. Despite its use, a significant portion of treated cancers still experience local and systemic recurrence. Accumulating evidence suggests that cryoablation has immunomodulatory properties, as it destroys tumors in situ and releases antigens along with stimulating signals, triggering a systemic immune response. However, those responses are usually weak and rarely induce clinically relevant therapeutic effects. Therefore, additional immunomodulatory approaches are required to enhance antitumor immunity. Combining ablation with immunotherapy has proven to be a potent in situ tumor vaccination approach that leads to control of local recurrence and metastasis.

Biography: Minhan is a Ph.D. candidate in Biomedical Engineering at the University of Minnesota, mentored by Prof. John Bischof.  Her research focuses on minimally invasive ablation therapies including cryosurgery, thermal therapy, and irreversible electroporation to uncover the role of focal therapy in priming the immune system. She also explores combining focal therapy with immunotherapy, such as checkpoint blockade, for improved primary and systemic cancer control. She holds a BS in BME from Shanghai Jiao Tong University.

Potential for Plant Cryobiology Research in Space
Many useful plant species with the potential for plant-based bioregenerative life support systems produce extremophile seeds with tolerance to multiple stressors, including desiccation, which allows for their transport through space in a dried state. However, other valuable species produce desiccation-sensitive seeds or are propagated clonally, and life sciences research in space has not yet addressed the challenge of alternative transport methods in microgravity for such material. Although liquid nitrogen storage is used on Earth for desiccation-sensitive germplasm, it poses atmospheric leakage problems to crewed spacecraft and therefore, liquid nitrogen-free cryogenic freezing could be an alternative. This webinar will discuss the context and potential for plant cryobiology research in space.

Biography: Through my research, I aim to understand seed traits involved in seed survival of (extreme) environmental conditions (both natural and ex situ) on Earth and in space. Currently, I am a Research Fellow in the Global Tree Seed Bank Programme funded by the Garfield Weston Foundation. In addition, I am leading several research projects selected by the European Space Agency for spaceflight inside and outside the International Space Station.

Atelerix: A Novel Solution for Hypothermic Cell, Tissue and Virus Preservation Matthew Gibson

Dr. Steven Swioklo Co-Founder & CSO, Atelerix Ltd., UK

Cells, tissues and viruses have a finite lifespan outside the closely regulated environment of the body or culture incubator. In order to effectively distribute samples between research, drug discovery, or clinical sites, samples can either be shipped fresh (at hypothermic temperatures) or frozen. Whilst freezing samples has the advantage of long-term storage, it is not suitable for cryo-sensitive cell populations, can be difficult to optimise for tissues and complex multicellular models, and can add logistical complications. This presentation will discuss the use of Atelerix’s technology to extend the shelf life of fresh biological samples and describe case studies across multiple sectors from drug discovery to cell-based therapy where it has been successfully implemented to increase geographical reach and improve flexibility.

Biography Steve Swioklo is CSO and Co-founder of Atelerix Ltd., a biotech company specialising in cell preservation technologies for drug discovery and cell therapy applications. He did his PhD training at the University of Reading (Pharmacology) before conducting post-doctoral research at Newcastle University. His post-doctoral research was focused on hydrogel-encapsulation of cells and tissues for room temperature preservation which led to spinning out Atelerix in June 2017.

Elena PopovaThe Use of Alginate Matrix in Cryopreserving Plant Genetic Resources
Dr. Elena Popova, Institute of Plant Physiology of Russian Academy of Sciences

Alginate beads inherited from the synthetic seed technology were successfully implemented for cryopreserving a wide range of plant genotypes. Various modifications of “encapsulation” appeared suitable for diverse materials including shoot tips, embryos, hairy and adventitious roots and cell cultures. Inevitably, as cryobiotechnology progressed, encapsulation was largely replaced by a droplet-vitrification, a more effective and adaptive method. The presentation will discuss the past experience and future potential of alginate gels in plant cryobiology, and their most recent implementation as a part of novel cryopreservation techniques.

Biography Elena is a cryobiologist and plant physiologist with particular interest in biodiversity conservation. Her research is focused on using in vitro and cryopreservation technologies for biobanking genetic collections of the endangered or clonally propagated plants. She has worked on plant biobanking projects at Global Crop Diversity Trust (Germany), the University of Guelph (Canada), National Agrobiodiversity Center (Republic of Korea) and other institutions developing and adapting cryopreservation protocols for various plant species.

Dr. Luciana Da Silveira Cavalcante University of Alberta, Canada
Dr. Lindgong Weng Sana Biotechnology, USA

Dr. Matthew Gibson Professor, University of Warwick, United Kingdom

Inspired by how nature has evolved ice binding, and other cryoprotective proteins we are interested in synthetic macromolecular cryoprotectants: polymers which can protect cells, proteins and other biologics. In this talk I will discuss our identification of potent macromolecular cryoprotectants and in particular their application to the cryopreservation of cells as 2D monolayers. We show how these allow near 100 % post-thaw recovery, enabling cells to be taken direct from the freezer and are ‘assay ready’: so the user needs no cell culture, passaging, cell counting etc. I will show the pathway of this to commercialization with our spin-out Cryologyx.

Matt is a Full Professor in the Department of Chemistry and Medical School at the University of Warwick, UK. He obtained his degree/PhD from the University of Durham, UK, and was a post-doc at EPFL Switzerland. Matt’s team develop biomaterials for challenges in health, biotechnology and affiliated areas. He is co-founder of Cryologyx Ltd.

Dr. Peter Kilbride Senior Scientist, Cytiva, United Kingdom

In the life sciences, one major hurdle is the practical challenges in making a great product have wide applicability.

Anja ThalhammerFlexibility matters – Towards understanding how disordered LEA proteins shape the tolerance to water loss
Dr. Anja Thalhammer 
Project Leader, University of Potsdam

LEA proteins are accumulated by many organisms encountering periods of water deficiency during their life cycles. While it seems clear that LEA proteins are main players in establishing freezing, dehydration and desiccation tolerance by stabilizing cellular membranes and macromolecules like enzymes and nucleic acids, we only have vague concepts of how they achieve this on the molecular level. I will talk about how LEA proteins structurally react to the water availability of their environment and exist in an equilibrium of hydration driven secondary and quaternary structural ensembles and present recent progress in our understanding of their intricate structure-function relationship.

Bio: Anja is based at the Physical Biochemistry Department at the University of Potsdam, which she first joined in 2014, initially as a postdoctoral researcher, since 2017 as a project leader. Anja did her diploma and PhD under the supervision of Dr. Dirk Hincha at the Max Planck Institute of Plant Physiology at Potsdam. Being a biologist by training, Anja studies folding, self-association and environmental interactions of proteins and peptides using interdisciplinary approaches.

Thomas BoothbyThe Role of Disordered Proteins in Tardigrade Desiccation Tolerance 
Dr. Thomas Boothby 
Assistant Professor, Department of Molecular Biology, University of Wyoming, USA

Tardigrades are a group of microscopic animals renowned for their ability to survive a number of environmental stresses. One such stress is severe water-loss, which these animals survive by entering into a dry state of suspended animation known as anhydrobiosis (life without water). How tardigrades mediate this process is largely unknown, but emerging evidence suggests that tardigrades, like any other stress tolerant organisms, utilize intrinsically disordered proteins to robustly survive the drying processes. Here, new insights into the role of disordered proteins and their mechanisms of action are presented.

Bio: Dr. Thomas Boothby completed his Bachelors degree at Tulane University (New Orleans, LA) and his PhD at University of Maryland where his PhD thesis dealt with post-transcriptional control of RNA during emergence from dormancy. After completing a postdoctoral position at University of North Carolina (how tardigrades survive desiccation), he is now Assistant Prof. at the University of Wyoming studying organismal stress tolerance.

Dr. Chia-Hsing Pi 
Senior Scientist, Process Development Engineering, Vertex Pharmaceuticals, USA

Since the first autologous CAR-T approved in 2017 and first allogeneic T-cell immunology approved in 2022, people start to pay more attentions on cryopreservation of cells. Suboptimal cryopreservation can lead not only to batch-to-batch variation, lowered cellular functionality and reduced cell yield. This requires attention to all aspects of the application of low temperatures: from the choice of freezing container and cryoprotectant, the cooling rate and its mode of delivery, the handling during storage and transportation, to the product thawing by the end-user. The speaker will share his experience and considerations with fit-for-purpose approaches for allogeneic and autologous cell therapies.

Bio: Chia-Hsing Pi, Ph.D., currently works at Vertex Pharmaceuticals as a senior scientist in process development engineering. Before joining Vertex, he worked in BlueRock Therapeutics for iPSC-derived cell therapy, where he supervised the cryopreservation process for all cell types including cardiology, neurology and immunology. He received his Ph.D in Allison Hubel, Ph.D.’s lab from University of Minnesota. In Graduate School, he used computational tools to understand interactions between osmolytes and optimize the preservation of heterogeneous populations of primary cells.

Tom WhaleIce Nucleation by Pollen and Fern Spore Derived Macromolecules: Atmospheric Implications and Cryobiological Applications

Dr. Thomas Whale
Leverhulme Early Career Fellow/Assistant Professor, Warwick University, UK

Around a decade ago it was discovered that some plant pollens produce water-soluble ice nucleating macromolecules. The chemical nature and biological function of these molecules remains poorly understood. This talk discusses our recent discovery of similar ice active molecules in fern spores, pointing to an ancient evolutionary origin of the nucleator. Further, we have also shown that the ice nucleation activity of the pollen derived molecules facilitates cryopreservation of a range of mammalian cell types in small-volume formats. Finally, some progress towards chemical identification of the ice nucleator is discussed.  

Bio: After completing a PhD in the Institute for Climate and Atmospheric Science at the University of Leeds and a brief postdoc in the School of Chemistry at Leeds, Dr. Tom Whale won a Leverhulme Early Career Fellowship in the Chemistry department at the University of Warwick, where he currently works. Tom’s research is focused on improving mechanistic understanding of heterogeneous ice nucleation and applying that knowledge to problems in cryobiology and atmospheric science.

Dr. Michael A. Menze - Professor and Associate Dean Research and Innovation, University of Louisville

The emerging role of proteinaceous liquid-liquid phase separation (LLPS) in the water-stress tolerance of animal cells will be discussed based on recent findings on two late embryogenesis abundant (LEA) proteins that are abundantly expressed in the anhydrobiotic stage of the brine shrimp Artemia franciscana. Both these proteins form proteinaceous protein droplets in vitro and biomolecular condensates (membraneless organelles) if ectopically expressed in cells. The propensity to selectively incorporate target proteins expands the range of mechanisms by which LEA proteins are thought to confer water-stress tolerance. Furthermore, recent progress in the dry preservation of red blood cells will be presented.

Dr. Michael A. Menze earned his doctoral degree in molecular physiology and biophysics by elucidating the role of allosteric regulation of respiratory pigments in the hypoxia tolerance of crustaceans. His postdoctoral work focused on the mechanisms of water-stress tolerance in invertebrates investigating the role of compatible organic osmolytes and proteaceous protectants in biostabilization. Dr. Menze continues to investigate the molecular basis of animal anhydrobiosis and develops biomimetics approaches to improve the long-term preservation of biologics.

Dr. Tim Menzen -Chief Technology Officer, Coriolis Pharma Research GmbH

Adeno-associated virus (AAV) is a promising vector for gene therapy. Liquid AAV formulations typically require storage below -60 °C to provide long-term stability. In contrast, freeze-dried formulations could enable storage at 2−8 °C. Different conditions for freeze-drying of AAV8 were evaluated and undesirable instability can be significantly reduced if secondary drying is performed at lower temperatures, kept as short as possible, and the residual moisture is kept between 1.5-2%. Moreover, a promising combination of phosphate buffer, trehalose, hydroxyectoine and poloxamer was found. These results pave the way for future optimizations of freeze-drying processes for AAV vector-based gene therapy products.

Dr. Tim Menzen is CTO of Coriolis Pharma. He is a pharmacist by training and received his PhD in the group of Prof. Frieß at the LMU in Munich. In 2014, Tim joined Coriolis Pharma.

Dr. Xiaoming "Shawn" He Professor, University of Maryland, United States

We developed a novel sand-based approach inspired by nature to enhance cell/tissue cryopreservation. This is demonstrated by cryopreserving human induced pluripotent stem cells (hiPSCs) as 3D microspheres with no serum, minimized cryoprotectant, and high cell survival. Furthermore, the cryopreserved hiPSCs retain high pluripotency and functions judged by pluripotency marker expression, cell cycle, and capability of differentiation into all the three different germ layers. This novel sand-mediated serum-free low-cryoprotectant cryopreservation method may greatly facilitate the convenient and ready availability of high-quality iPSCs and possibly many other types of cells/tissues for the emerging cell-based medicine.

When a biological sample is cryopreserved, the problem of recrystallization can arises during rewarming. However, if it carries out fast and homogeneous heating this problem is avoided. From CryoBioTech we can offer the solution: by using HIFU as a rewarming technique, the recrystallization is solved. In this work, the survival rate obtained in Caenorhabditis elegans model is presented a proof of this scalable technique.

Laura Encabo was born in 1996 in Lucena, Córdoba (Spain), and is currently living in Seville. She is graduated in Pharmacy from University of Granada (2019) where she developed her knowledge in biotechnology, biochemistry and pharmacology. Laura developed her final degree dissertation at the prestigious CSIC-IACT (Andalusian Institute of Earth Sciences in collaboration with the Superior Council of Scientific Investigations) facilities in Granada, where she worked on improving the physicochemical properties of anti-inflammatory drugs through the use of the cocrystallization technique. Laura Encabo obtained a Research Contract from the Regional Government of Andalusia that allowed her to connect with the world of cryobiology. The results she achieved in the first months of work prompted her to develop her PhD at CryoBioTech with Dr. Risco, a multidisciplinary biologist-engineer group at Engineering School at University of Seville. Since she began her research stage, she has collaborated at different levels: proof of principles with the C. elegans animal model and its rewarming with HIFU (High Intensity Focused Ultrasound), evaluation of short-term memory after cryopreservation, and improvement of cryoprotectant cocktails. Currently, his research is focused on cryopreservation of the heart of mice and rats, applying HIFU as the main rewarming technique.

Nucharin Songsasen - Head, Center for Species Survival, Smithsonian’s National Zoo & Conservation Biology Institute, Washington DC, USA

This presentation will discuss the state-of-the-art, applications, and challenges of gamete and reproductive tissue cryopreservation in endangered species conservation.

Nucharin Songsasen is the Center Head of the Center for Species Survival. She joined the Smithsonian in 2002 when offered the opportunity to study the reproductive biology of domestic and wild carnivores. Over the years, she built the Global Canid Conservation Program and expanded this conservation and research initiative from a laboratory setting to field conservation in range countries, including Brazil and Thailand.

Nucharin is a leading expert in the field of canid reproductive biology. Research conducted in her laboratory focuses on developing innovative technologies to rescuing valuable genetics from wild canids and felids, while improving human reproductive health. In addition to reproductive research, she has collaborated with SCBI scientists and developed partnerships with national and international governmental and non-governmental organizations to address many threats to the sustainability of wild canids, including the maned wolf, dhole, red wolf and African painted dog, living in zoos or the wild. Since 2009, she has led the collaboration with USGS’s Patuxent Wildlife Research Center in studying the reproductive biology and endocrinology of the whooping crane and identifying the causes of poor reproduction in this endangered species.

Nucharin has adjunct appointments at the University of Maryland, Cornell University and George Mason University. She is also a member of the IUCN’s Canid Specialist Group (CSG), the coordinator of CSG’s Dhole Working Group and the Maned wolf Species Survival Plan (MWSSP) as well as Reproductive Advisor to the Canid Taxon Advisory Group.

Nucharin received her Doctor of Veterinary Medicine degree from the Kasetsart University in Thailand, and Master of Science and doctoral degrees from the University of Guelph in Canada.


Iqra Azam - Graduate Student, Department of Biology, University of Saskatchewan, Canada

There has been recent success in high-subzero storage of livers, however longer storage durations achieved in liquid nitrogen require high concentrations of toxic and mechanically disrupting cryoprotectants. While there has been some work on cryobiologically relevant hepatocyte biophysics, here I show how the unique cell anatomy of hepatocytes affects basic assumptions of modelling in cryobiology. Moreover, I show how these structures are affected in-situ using 4D microscopy techniques. Finally, I present preliminary data on preventing osmotic damage during CPA equilibration.

Iqra Azam is a Ph.D. student working in James Benson's lab in the Department of Biology at the University of Saskatchewan. During her Masters, she evaluated insects as bioindicators of heavy metal contamination and assessed the spatial and temporal distribution of metals using Geographical Information System (GIS) techniques. Her current research focuses on biophysical characterization and mathematical optimization of cryopreservation of liver cells and tissues. Towards this, she has developed real-time volumetric quantification of adherent cells by using modern 3D & 4D microscopic imaging techniques. She is also developing an imaging protocol to track cells and nuclei within a live precision-cut tissue slice and for quantification of tissue expansion and shrinkage. She enjoys working with microscopes and learning new tools to do cell and tissue imaging.
