Abstract
Cryopreservation is a crucial step in the supply process of off-the-shelf chimeric antigen receptor engineered natural killer (CAR-NK) cell products. Concerns have been raised over the clinical application of dimethyl sulfoxide (Me2SO) due to the potential for adverse reactions following infusion and limited cell-specific cytotoxic effects if misapplied. In this study, we developed a Me2SO-free cryopreservation medium specifically tailored for CAR-NK cells to address this limitation. The cryopreservation medium was formulated using human serum albumin (HSA) and glycerol as the base components. Following initial screening of seven clinically-compatible solutions, four with cryoprotective properties were identified. These were combined and optimized into a single formulation: IF-M. The viability, phenotype, and function of CAR-NK cells were evaluated after short-term and long-term cryopreservation to assess the effectiveness of IF-M, with Me2SO serving as the control group. The viability and recovery of CAR-NK cells in the IF-M group were significantly higher than those in the Me2SO group within 90 days of cryopreservation. Moreover, after 1 year of cryopreservation the cytotoxic capacity of CAR-NK cells cryopreserved with IF-M was comparable to that of fresh CAR-NK cells and significantly superior to that of CAR-NK cells cryopreserved in Me2SO. The CD107a expression intensity of CAR-NK cells in IF-M group was significantly higher than that of Me2SO group. No statistical differences were observed in other indicators under different cryopreservation times. These results underscore the robustness of IF-M as a suitable replacement for traditional Me2SO-based cryopreservation medium for the long-term cryopreservation and clinical application of off-the-shelf CAR-NK cells.

Cryopreserved red blood cells maintain allosteric control of oxygen binding when utilizing trehalose as a cryoprotectant. Cryobiology 2024; 114:104793.

Abstract
One of the most common life-saving medical procedures is a red blood cell (RBC) transfusion. Unfortunately, RBCs for transfusion have a limited shelf life after donation due to detrimental storage effects on their morphological and biochemical properties. Inspired by nature, a biomimetics approach was developed to preserve RBCs for long-term storage using compounds found in animals with a natural propensity to survive in a frozen or desiccated state for decades. Trehalose was employed as a cryoprotective agent and added to the extracellular freezing solution of porcine RBCs. Slow cooling (-1 °C min-1) resulted in almost complete hemolysis (1 ± 1 % RBC recovery), and rapid cooling rates had to be used to achieve satisfactory cryopreservation outcomes. After rapid cooling, the highest percentage of RBC recovery was obtained by plunging in liquid nitrogen and thawing at 55 °C, using a cryopreservation solution containing 300 mM trehalose. Under these conditions, 88 ± 8 % of processed RBCs were recovered and retained hemoglobin (14 ± 2 % hemolysis). Hemoglobin's oxygen-binding properties of cryopreserved RBCs were not significantly different to unfrozen controls and was allosterically regulated by 2,3-bisphosphoglycerate. These data indicate the feasibility of using trehalose instead of glycerol as a cryoprotective compound for RBCs. In contrast to glycerol, trehalose-preserved RBCs can potentially be transfused without time-consuming washing steps, which significantly facilitates the usage of cryopreserved transfusible units in trauma situations when time is of the essence.

Abstract
Cryopreservation of red blood cells (RBCs) plays a vital role in preserving rare blood and serologic testing, which is essential for clinical transfusion medicine. The main difficulties of the current cryopreservation technique are the high glycerol concentration and the tedious deglycerolization procedure after thawing. In this study, we explored a microencapsulation method for cryopreservation. RBC-hydrogel microcapsules with a diameter of approximately 2.184 ± 0.061 mm were generated by an electrostatic spraying device. Then, 0.7 M trehalose was used as a cryoprotective agent (CPA), and microcapsules were adhered to a stainless steel grid for liquid nitrogen freezing. The results show that compared with the RBCs frozen by cryovials, the recovery of RBCs after microencapsulation is significantly improved, up to a maximum of more than 85%. Additionally, the washing process can be completed using only 0.9% NaCl. After washing, the RBCs maintained their morphology and adenosine 5'-triphosphate (ATP) levels and met clinical transfusion standards. The microencapsulation method provides a promising, referenceable, and more practical strategy for future clinical transfusion medicine.

Abstract
Currently, glycerol is a conventional cryoprotectant of human red blood cells (hRBCs), but the time-consuming thawing and deglycerolization processes are essential before transfusion. Much of the research up to now has been conducted on the delivery of impermeable trehalose to hRBCs at 37 °C, but the cryoprotective effect of trehalose and deterioration of cells still remain challenging. Encouraged by the interaction of hydrophobic or cationic groups on cell membranes and osmotic stabilization, herein, we propose a novel cryopreservation system to facilitate trehalose entry into hRBCs at 4 °C and pH 7.4. High intracellular trehalose contents and cryosurvival of hRBCs were achieved with small function variations via the assistance of self-assembled nanoparticles of alkylated ε-poly(L-lysine) (ε-PL) along with poly(vinyl pyrrolidone) (PVP). The effect of amphipathic alkylated ε-PL with various alkyl chains and grafting ratios on membrane perturbation with protection of PVP was systematically investigated. Overall, by the combination of alkylated ε-PL and PVP, the intracellular trehalose could be enhanced to 109.7 ± 6.1 mM and subsequently hRBC cryosurvival reached 91.7 ± 5.5%, significantly higher than those containing trehalose only, 11.9 ± 1.1 mM and 50.0 ± 2.1%, respectively. It was observed that the biocompatible trehalose-loading system could benefit glycerol-free cryopreservation of hRBCs and also provide a feasible way for impermeable biomacromolecule delivery.

Abstract
Despite a vast amount of different methods, protocols and cryoprotective agents (CPA), stem cells are often frozen using standard protocols that have been optimized for use with cell lines, rather than with stem cells. Relatively few comparative studies have been performed to assess the effects of cryopreservation methods on these stem cells. Dimethyl sulfoxide (DMSO) has been a key agent for the development of cryobiology and has been used universally for cryopreservation. However, the use of DMSO has been associated with in vitro and in vivo toxicity and has been shown to affect many cellular processes due to changes in DNA methylation and dysregulation of gene expression. Despite studies showing that DMSO may affect cell characteristics, DMSO remains the CPA of choice, both in a research setting and in the clinics. However, numerous alternatives to DMSO have been shown to hold promise for use as a CPA and include albumin, trehalose, sucrose, ethylene glycol, polyethylene glycol and many more. Here, we will discuss the use, advantages and disadvantages of these CPAs for cryopreservation of different types of stem cells, including hematopoietic stem cells, mesenchymal stromal/stem cells and induced pluripotent stem cells.

Abstract
Dimethylsufoxide (DMSO) being universally used as a cryoprotectant in clinical adoptive cell-therapy settings to treat hematological malignancies and solid tumors is a growing concern, largely due to its broad toxicities. Its use has been associated with significant clinical side effects-cardiovascular, neurological, gastrointestinal, and allergic-in patients receiving infusions of cell-therapy products. DMSO has also been associated with altered expression of natural killer (NK) and T-cell markers and their in vivo function, not to mention difficulties in scaling up DMSO-based cryoprotectants, which introduce manufacturing challenges for autologous and allogeneic cellular therapies, including chimeric antigen receptor (CAR)-T and CAR-NK cell therapies. Interest in developing alternatives to DMSO has resulted in the evaluation of a variety of sugars, proteins, polymers, amino acids, and other small molecules and osmolytes as well as modalities to efficiently enable cellular uptake of these cryoprotectants. However, the DMSO-free cryopreservation of NK and T cells remains difficult. They represent heterogeneous cell populations that are sensitive to freezing and thawing. As a result, clinical use of cryopreserved cell-therapy products has not moved past the use of DMSO. Here, we present the state of the art in the development and use of cryopreservation options that do not contain DMSO toward clinical solutions to enable the global deployment of safer adoptively transferred cell-based therapies.

Abstract
We tested the efficacy of lactated Ringer's solution with 3% trehalose and 5% dextran 40 (LR-3T-5D) as a vehicle solution for cryopreservation using human adipose-derived mesenchymal stromal cells (hADSCs) with dimethyl sulfoxide (Me2SO). We also tested the effect of the Me2SO concentration in the cryopreservation solution, and the effect of washing with lactated Ringer's solution with 3% trehalose (LR-3T) and replacement with LR-3T or LR-3T-5D. LR-3T-5D was more effective for cell viability, viable cell recovery ratio, annexin V-positive ratio, and colony-forming capacity as a vehicle solution for cryopreservation with 10% Me2SO than LR. The additive effects as cryoprotectants of trehalose and dextran 40 were confirmed to be dose dependent. The cell viability, cell proliferation ability, cell differentiation ability, and the ratio of cell surface positive/negative markers of hADSCs were well maintained after cryopreservation with LR-3T-5D containing 10% Me2SO in liquid nitrogen or in a -80 °C freezer. The cell viability and the proliferation curve in LR-3T-5D with 5% Me2SO were comparable to those with 10% Me2SO. LR-3T-5D was superior to LR-3T as a replacement solution in terms of viability and annexin V positivity. Our data showed that LR-3T-5D is effective as a vehicle solution for cryopreservation. Reducing Me2SO concentration to 5%, and washing and replacement with fresh LR-3T and LR-3T-5D after thawing, are feasible approaches to maintain cryopreservation efficacy.

Abstract
Prior to transfusion of red blood cells (RBCs), recipients must be tested for the presence of alloantibodies to avoid immune complications. Liquid-preserved reagent RBCs with known blood group antigen phenotypes are used for testing. However, these reagents have practical constraints, including limited shelf-life and require constant refrigeration. To address these issues, we explore the effects of rapid freeze-drying conditions with trehalose cryoprotectant (0.1-1 M concentrations) on human RBCs and storage of freeze-dried RBCs (FDRBCs) at room temperature (RT) for up to 12 months. We report that rapid freeze-drying of RBCs for 2.5 hr with 0.5 M trehalose achieves recoverable cells with near-normal morphological shape, although size-reduced. The FDRBCs are metabolically active and functional in antibody-agglutination tests by the column agglutination test (CAT) for ABO and Rhesus-D blood group antigens. Expression of the Duffy blood group protein (CD234) decreases by 50% after freeze-drying RBCs. The initial recovery rate is ≤25%; however, 43% of these FDRBCs are still recoverable after RT storage for 12 months. In this proof-of-principle study, we show that rapid freeze-drying can stabilize RBCs. Further refinements to improve the recovery rate and preservation of antigenic epitopes will make FDRBCs a practical alternative source of reagent RBCs for pre-transfusion alloantibody identification.

Abstract
Cryopreservation of red blood cells (RBCs) holds great potential benefits for supplying transfusion timely in emergencies. Currently, glycerol is the main cryoprotectant permitted in clinical therapy for RBCs cryopreservation, but its broad application is limited by the toxicity and complex deglycerolization process. Successful cryopreservation of RBCs using more effective materials should be studied to reduce freezing damage, increase biocompatibility, and save processing time. Herein, a simple protocol using natural cryoprotectants combinations of l-proline and trehalose attains a low degree of hemolysis (11.2 ± 2.73%) after thawing compared to glycerol. Furthermore, the morphology of RBCs and the activities of Na+/K+-ATPase and Ca2+/Mg2+-ATPase maintain well. Further mechanism study shows that l-proline plays an important role in decreasing the freezing points and inhibiting the growth of ice crystal by permeating into cells during the freezing process. While trehalose works as an inhibitor of ice growth in the freezing process and ice recrystallization in the thawing process. This simple l-proline & trehalose combinations protocol is a promising method to replace current time-consuming and labor-intensive cryopreservation methods of RBCs.

In avian species, cryopreservation of semen is necessary for developing sperm cryobanks. It is very difficult, however to cryopreserve turkey sperm and have sperm be viable after thawing. Glycerol, the commonly used sperm cryoprotectant in many species, is toxic to sperm of avian species. The aim of this study was to evaluate whether the non-permeating dextran was effective for the cryopreservation and maintenance of turkey spermatozoa viability after thawing, avoiding the use of permeating cryoprotectants. Turkey sperm were diluted with a medium supplemented with 11% glycerol or dextran with a 1,000 molecular weight (MW), dextran with a 10,000 MW, or dextran with a 20,000 MW each at a 2%, 5%, or 10% concentration. Sperm kinetic characteristics, membrane and acrosome integrity (AI), and the capacity of spermatozoa to interact with the autologous perivitelline layer were evaluated after equilibration and cryopreservation. Results indicate that with use of glycerol and the 1,000 MW dextran there was lesser sperm viability after both equilibration and cryopreservation, compared with use of the 10,000 or 20,000 MW dextran compounds. There was a greater cryoprotective effect with the 10,000 and 20,000 MW dextran compounds at the 10% concentration with spermatozoa maintaining a greater functionality and capacity to interact with the autologous perivitelline layer. In conclusion, the results of this study indicate turkey spermatozoa could be effectively cryopreserved in extender without the use of glycerol as a penetrating cryoprotectant but with the use of the 10,000 or 20,000 MW dextran compounds at a 10% extender concentration.

Abstract
The ability to cryopreserve natural killer (NK) cells has a significant potential in modern cancer immunotherapy. Current cryopreservation protocols cause deterioration in NK cell viability and functionality. This work reports the preservation of human cytokine-activated NK cell viability and function following cryopreservation using a cocktail of biocompatible bioinspired cryoprotectants (i.e., dextran and carboxylated ε-poly-L-lysine). Results demonstrate that the recovered NK cells after cryopreservation and rewarming maintain their viability immediately after thawing at a comparable level to control (dimethyl sulfoxide-based cryopreservation). Although, their viability drops in the first day in culture compared to controls, the cells grow back to a comparable level to controls after 1 week in culture. In addition, the anti-tumor functional activity of recovered NK cells demonstrates higher cytotoxic potency against leukemia cells compared to control. This approach presents a new direction for NK cell preservation, focusing on function and potentially enabling storage and distribution for cancer immunotherapy.

Abstract
A series of polyampholytes based on different molar ratios on N, N-dimethylaminopropyl methacrylamide (DMAPMA), acrylic acid (AA), and optionally, N- tert-butylacrylamide ( t-BuAAm), were prepared by free radical copolymerization, and tested as DMSO-free cryoprotective agents for 3T3 fibroblast cells by using a standard freeze-rethaw protocol. Polybetaines prepared by reaction of DMAPMA homo and copolymers with 1,3-propane sultone were used as additional controls. Results showed strong effects of copolymer composition, molecular weight, polymer and NaCl concentrations, on post-thaw cell viability. Binary (DMAPMA/AA) copolymers showed best post-thaw cell viability of 70% at a 30/70 mol % ratio of DMAPMA/AA, which increased to 90% upon introduction of 9 mol % t-BuAAm while maintaining the 30/70 mol % cation/anion ratio. The use of acrylamide linkages in DMAPMA ensures absence of hydrolytic loss of cationic side chains. These polyampholytes were found to decrease ice crystal size and to form a polymer-rich, ice-free layer around cells, reducing damage from intercellular ice crystals during both freezing and thawing steps. These polyampholytes also dehydrate cells during freezing, which helps protect cells from intracellular ice damage. While cell viability immediately after thawing was high, subsequent culturing revealed poor attachment and long-term viability, which is attributed to residual cell damage from intracellular ice formation. Addition of 2 wt % DMSO or 1% BSA to the polymer-based freeze medium was found to mitigate this damage and result in post-thaw viabilities matching those achieved with 10 wt % DMSO.

Abstract
Freeze-drying is a promising approach for the long-term storage of erythrocytes at room temperature. Studies have shown that trehalose loaded into erythrocytes plays an important role in protecting erythrocytes against freeze-drying damage. Due to the impermeability of the erythrocyte membrane to trehalose, many methods have been developed to load trehalose into erythrocytes. However, these methods usually require multistep manual manipulation and long processing time; the adopted protocols are also diverse and not standardized. Thus, we develop an osmotically-based trehalose-loading microdevice (TLM) to rapidly, continuously, and automatically produce erythrocytes with loaded trehalose. In the TLM, trehalose is loaded through the erythrocyte membrane pores induced by hypotonic shock; then, the trehalose-loaded erythrocytes are rinsed to remove hemoglobin molecules and cell fragments, and the extracellular solution is restored to the isotonic state by integrating a rinsing-recovering design. First, the mixing function and the rinsing-recovering function were confirmed using a fluorescent solution. Then, the performance of the TLM was evaluated under various operating conditions with respect to the loading efficiency of trehalose, the hemolysis rate of erythrocytes (ϕ), the recovery rate of hemoglobin in erythrocytes (φ), and the separation efficiency of the TLM. Finally, the preliminary study of the freeze-drying of erythrocytes with loaded trehalose was accomplished using the TLM. The results showed that under the designated operating conditions, the loading efficiency for human erythrocytes reached ~21 mM in ~2 min with a ϕ value of ~17% and a φ value of ~74%. This study provides insights into the design of the on-chip loading of trehalose into erythrocytes and promotes the automation of life science studies on biochips.

Abstract
Correlating live-cell imaging with electron microscopy is among the most promising approaches to relate dynamic functions of cells or small organisms to their underlying ultrastructure. The time correlation between light and electron micrographs, however, is limited by the sample handling and fixation required for electron microscopy. Current cryofixation methods require a sample transfer step from the light microscope to a dedicated instrument for cryofixation. This transfer step introduces a time lapse of one second or more between live imaging and the fixed state, which is studied by electron microscopy. In this work, we cryofix Caenorhabditis elegans directly within the light microscope field of view, enabling millisecond time-correlated live imaging and electron microscopy. With our approach, the time-correlation is limited only by the sample cooling rate. C. elegans was used as a model system to establish compatibility of in situ cryofixation and subsequent transmission electron microscopy (TEM). TEM images of in situ cryofixed C. elegans show that the ultrastructure of the sample was well preserved with this method. We expect that the ability to correlate live imaging and electron microscopy at the millisecond scale will enable new paradigms to study biological processes across length scales based on real-time selection and arrest of a desired state. LAY DESCRIPTION Researchers seek to link cellular functions to their smallest structural components. Currently this requires correlation of two imaging techniques, live imaging and electron microscopy. Current correlative methods, however, have limited time resolution due to the sample preparation procedures for electron microscopy. Following live imaging, samples are transferred from the light microscope to a cryofixation, or ultra-fast freezing, instrument. The biological process progresses until the sample freezes, 1 second or more after the last live image. In this work, samples are cryofixed directly within the light microscope field of view. By eliminating the transfer step, time correlation between light and electron microscopy images of our samples is limited only by the freezing rate to the order of milliseconds rather than seconds.

Abstract
Stem cells are an important tool for the study of hematopoiesis. Despite developments in cryopreservation, post-thaw cell death remains a considerable problem. Cryopreservation protocol should limit cell damage due to freezing and ensure the recovery of the functional cell characteristics after thawing. Thus, the use of cryoprotectants is essential. In particular, the efficacy of trehalose has been reported for clinical purposes in blood stem cells. The aim of the current study was to establish an efficient method for biological research based on the use of trehalose, to cryopreserve pure peripheral blood stem cells. The efficacy of trehalose was assessed in vitro and the cell viability was evaluated. The data indicate that trehalose improves cell survival after thawing compared with the standard freezing procedure. These findings could suggest the potential for future trehalose application for research purposes in cell cryopreservation.

Abstract
A structural understanding of whole cells in three dimensions at high spatial resolution remains a significant challenge and, in the case of X-rays, has been limited by radiation damage. By alleviating this limitation, cryogenic coherent diffractive imaging (cryo-CDI) can in principle be used to bridge the important resolution gap between optical and electron microscopy in bio-imaging. Here, the first experimental demonstration of cryo-CDI for quantitative three-dimensional imaging of whole frozen-hydrated cells using 8 keV X-rays is reported. As a proof of principle, a tilt series of 72 diffraction patterns was collected from a frozen-hydrated Neospora caninum cell and the three-dimensional mass density of the cell was reconstructed and quantified based on its natural contrast. This three-dimensional reconstruction reveals the surface and internal morphology of the cell, including its complex polarized sub-cellular structure. It is believed that this work represents an experimental milestone towards routine quantitative three-dimensional imaging of whole cells in their natural state with spatial resolutions in the tens of nanometres.

Abstract
Cryopreservation refers to the long-term storage of mammalian cells. Mammalian serum is generally used as a cryoprotectant, but is associated with problems including the risk of contamination by pathogens and quality control issues. Therefore, a serum-free cryopreservation method needs to be established. In this study, we focused on rakkyo fructan, a fructose polymer, derived from the Japanese shallot as an alternative factor to serum. Fructan contributes to tolerance to frost and dehydration in plants by stabilizing the plant membrane. However, whether fructan protects mammalian cells against freezing stress remains unknown. The ability of rakkyo fructan to be an alternative cryoprotectant to fetal bovine serum (FBS) was examined in the present study. 2E3-O, a mouse hybridoma, was preserved in rakkyo fructan, was highly viable after being defrosted, and then proliferated rapidly. When rakkyo fructan was combined with dimethylsulfoxide (DMSO), its ability to protect the hybridoma against freezing stress was improved. The rakkyo fructan and DMSO mixture was used in the cryopreservation of the mammalian cell lines CHO-DP12, a producer of recombinant antibodies, and HepG2, human hepatoma cells frequently tested in bio-artificial livers. Following the freezing and thawing processes, CHO-DP12 cells retained their ability to produce recombinant antibodies and as did HepG2 cells for albumin and mRNA expression of cytochrome P450 enzymes. These results indicate that rakkyo fructan is a promising cryoprotectant that prevents mammalian cells from freezing stress similar to FBS.

Abstract
Cultivation of undifferentiated pluripotent stem cells (PSCs) as aggregates has emerged as an efficient culture configuration, enabling rapid and controlled large scale expansion. Aggregate-based PSC cryopreservation facilitates the integrated process of cell expansion and cryopreservation, but its feasibility has not been demonstrated. The goals of current study are to assess the suitability of cryopreserving intact mouse embryonic stem cell (mESC) aggregates and investigate the effects of aggregate size and the formulation of cryopreservation solution on mESC survival and recovery. The results demonstrated the size-dependent cell survival and recovery of intact aggregates. In particular, the generation of reactive oxygen species (ROS) and caspase activation were reduced for small aggregates (109 ± 55 μm) compared to medium (245 ± 77 μm) and large (365 ± 141 μm) ones, leading to the improved cell recovery. In addition, a defined protein-free formulation was tested and found to promote the aggregate survival, eliminating the cell exposure to animal serum. The cryopreserved aggregates also maintained the pluripotent markers and the differentiation capacity into three-germ layers after thawing. In summary, the cryopreservation of small PSC aggregates in a defined protein-free formulation was shown to be a suitable approach toward a fully integrated expansion and cryopreservation process at large scale.

Abstract
One of the least recognized causes of cellular damage during ex vivo preservation of red blood cells is oxidative injury to the hemoglobin. The latter has been associated with hemolysis through the release of toxic substances and oxidation of vital cell components. This review delineates some of the major pathways that link hemoglobin oxidation and cellular damage, and summarizes the incidence of red blood cell oxidative injury during hypothermic storage, cryopreservation and desiccation stress. Red blood cell hypothermic storage, despite its success, is not exempt from oxidative injury. Growing evidence portrays a time-dependant oxidative assault including formation of reactive oxygen species, attachment of denatured hemoglobin to membrane phospholipids and the release of hemoglobin-containing membrane microvesicles throughout storage. Similar symptoms have been observed in attempts to stabilize red blood cells in the dried state, in which methemoglobin levels of reconstituted red blood cells reached 50%. Factors affecting the rate of hemoglobin oxidation during red blood cell ex vivo storage include compromised antioxidant activity, high concentrations of glucose in the storage media and the presence of molecular oxygen. Hemoglobin oxidation largely dictates our ability to effectively preserve red blood cells. Understanding its origins along with investigating methods to minimize it can significantly improve the quality of our future blood products.

Abstract
D-allose, an aldo-hexose, is a rare sugar whose biological functions remain largely unclear. Recently, we demonstrated a novel inhibitory effect of D-allose on production of reactive oxygen species (ROS). Here, we focused on investigating cryoprotective effects of D-allose on cell viability. Mammalian cell lines including OVCAR-3 (human ovarian cancer), HeLa (human cervical cancer), HaCaT (human skin keratinocytes), HDF (human dermal fibroblasts) and NIH3T3 (murine fibroblasts) cells were frozen at -80 degrees C in culture media with various D-allose concentrations. Cells were allowed to recover for 24 h, 1 week or 1 month prior to survival assessment using the trypan blue dye exclusion test, when cell proliferation was evaluated by MTT assay. A beneficial protective role of D-allose on cell survival was found, similar to that of trehalose (disaccharide of glucose), a recognized cryoprotectant. The results suggest that D-allose as a sole additive may provide effective protection for mammalian cells during freezing. Practical studies now need to be performed with D-allose, for example to determine optimal freezing protocols and explore potential for preservation of tissues or organs at non-freezing temperatures.

Abstract
Cryopreservation plays a significant function in tissue banking and will presume yet larger value when more and more tissue-engineered products will routinely enter the clinical arena. The most common concept underlying tissue engineering is to combine a scaffold (cellular solids) or matrix (hydrogels) with living cells to form a tissue-engineered construct (TEC) to promote the repair and regeneration of tissues. The scaffold and matrix are expected to support cell colonization, migration, growth and differentiation, and to guide the development of the required tissue. The promises of tissue engineering, however, depend on the ability to physically distribute the products to patients in need. For this reason, the ability to cryogenically preserve not only cells, but also TECs, and one day even whole laboratory-produced organs, may be indispensable. Cryopreservation can be achieved by conventional freezing and vitrification (ice-free cryopreservation). In this publication we try to define the needs versus the desires of vitrifying TECs, with particular emphasis on the cryoprotectant properties, suitable materials and morphology. It is concluded that the formation of ice, through both direct and indirect effects, is probably fundamental to these difficulties, and this is why vitrification seems to be the most promising modality of cryopreservation.

Abstract
The stability of new supramolecular nanoassemblies (nanogels), based on the association of a hydrophobically modified dextran (MD) and a beta-cyclodextrin polymer (pbetaCD), has been studied by two complementary methods: (i) size measurements and (ii) turbidity experiments using a Turbiscan optical analyser. Nanogels of about 120-150nm were obtained whatever the concentration of the two polymer solutions. At low concentrations, the suspensions presented little mean diameter variations upon storage. However, the concentrated ones tended to destabilize and their mean diameter increased upon time. Size measurements and Turbiscan investigations have demonstrated that destabilization in the MD-pbetaCD nanogel suspension was only due to particle aggregation and/or fusion, as no sedimentation or creaming occurred. The destabilization of MD-pbetaCD suspensions led to the formation of a highly viscous phase, as a final state. Moreover, the two methods have shown that aggregation and/or fusion phenomena were more pronounced in the concentrated MD-pbetaCD suspensions than in the diluted ones. The stability of MD-pbetaCD suspensions could be improved by their storage at 4 degrees C. Finally, freeze-drying was found to be a convenient method for the long-time storage of MD-pbetaCD nanoassemblies.

Abstract
Freezing and lyophilization are common methods used for preservation and storage of microorganisms during the production of concentrated starter cultures destined for industrial fermentations or product formulations. The compatible solute trehalose has been widely reported to protect bacterial, yeast and animal cells against a variety of environmental stresses, particularly freezing and dehydration. Analysis of the Lactobacillus acidophilus NCFM genome revealed a putative trehalose utilization locus consisting of a transcriptional regulator, treR; a trehalose phosphoenolpyruvate transferase system (PTS) transporter, treB; and a trehalose-6-phosphate hydrolase, treC. The objective of this study was to characterize the tre locus in L. acidophilus and determine whether or not intracellular uptake of trehalose contributes to cryoprotection. Cells subjected to repeated freezing and thawing cycles were monitored for survival in the presence of various concentrations of trehalose. At 20% trehalose a 2-log increase in survival was observed. The trehalose PTS transporter and trehalose hydrolase were disrupted by targeted plasmid insertions. The resulting mutants were unable to grow on trehalose, indicating that both trehalose transport into the cell via a PTS and hydrolysis via a trehalose-6-phosphate hydrolase were necessary for trehalose fermentation. Trehalose uptake was found to be significantly reduced in the transporter mutant but unaffected in the hydrolase mutant. Additionally, the cryoprotective effect of trehalose was reduced in these mutants, suggesting that intracellular transport and hydrolysis contribute significantly to cryoprotection.

Abstract
Preservation and long-term storage of red blood cells (RBCs) is needed to ensure a readily available, safe blood supply for transfusion medicine. Effective preservation procedures are required at various steps in the production of a RBC product including testing, inventory, quality control, and product distribution. Biopreservation is the process of maintaining the integrity and functionality of cells held outside the native environment for extended storage times. The biopreservation of RBCs for clinical use can be categorized based on the techniques used to achieve biologic stability and ensure a viable state after long-term storage. This paper will review the history, science, current practices, and emerging technologies of current RBC biopreservation approaches: hypothermic storage, cryopreservation, and lyophilization.

Abstract
A new assay has been developed to study the osmotic fragility of red blood cells (RBCs) and the involvement of oxygen-derived free radicals and other oxidant species in causing human red blood cell hemolysis. The amount of hemoglobin released into the supernatant, which is a measure of human red blood cell hemolysis, is monitored using an ELISA reader. This ELISA-based osmotic fragility test compared well with the established osmotic fragility test, with the added advantage of significantly reduced time and the requirement of only 60 mul of blood. This small amount of blood was collected fresh by finger puncture and was immediately diluted 50 times with PBS, thus eliminating the use of anticoagulants and the subsequent washings. Since exposure of RBCs to 400 Gy gamma radiation caused less than 5% hemolysis 24 h after irradiation, the RBC hemolysis induced by gamma radiation was amplified by irradiating the cell in hypotonic saline. The method was validated by examining the protective effect of Trolox, an analog of vitamin E and reduced glutathione (GSH), a well-known radioprotector, against human RBC hemolysis caused by the combined action of radiation and osmotic stress. Trolox, a known membrane stabilizer and an antioxidant, and GSH offered significant protection. This new method, which is simple and requires significantly less time and fewer RBCs, may offer the ability to study the effects of antioxidants and membrane stabilizers on human red blood cell hemolysis induced by radiation and oxidative stress and assess the osmotic fragility of erythrocytes.

Abstract
The promise of dried state preservation is based on the hypothesis that lowering molecular mobility to halt chemical reaction and deterioration rates is the primary factor for the long-term stability of the dried specimen. In this research, the feasibility of utilizing isothermal, isobaric vitrification as an economical alternative to the preservation technologies currently in use (mainly, cryopreservation and lyophilization) is explored. Desiccation and vitrification kinetics of model trehalose and trehalose-dextran systems were examined using gravimetric analysis, modulated differential scanning calorimetry, and X-ray crystallography. It was shown that vitrification can be achieved isothermally without crystallization and that vitrification of trehalose solutions can be significantly accelerated by incorporating high-molecular-weight dextrans. Additionally, it was shown that, for the same water content, the glass transition temperature of the trehalose-dextran solution is significantly higher than that of the binary trehalose solution, making the glassy state achievable and storage feasible.

Abstract
The ever-increasing demand for blood products challenges scientists to develop new and more effective techniques for their preservation. The progress of these novel preservation technologies uses a wide variety of cryoprotectant, lyoprotectant, and other preservatives, which will need to be explored and assessed for their biological effects during blood product formulation. The leading factor in protectant selection is for their ability to provide superior preservation for a particular blood product. We believe that such protectants used in blood product development should also be evaluated for their ability to preserve normal hemostasic mechanisms. In this review, high-molecular-weight cryoprotectants, lyoprotectants, polyols, amino acids, antioxidants, and surfactants, used because of their protective properties, were evaluated for their possible role in relation to their effect on normal hemostatic mechanisms.

Abstract
Bullous pemphigoid antigen 180 (BP180) is targeted by autoantibodies in a variety of subepidermal blistering skin diseases. We have recently developed a simple, highly specific and sensitive immunofluorescence (IF) assay for the detection of circulating antibodies against BP180. This novel assay involves the expression of full-length (FL) BP180 in Sf21 insect cells that are then examined under IF microscopy after staining with anti-BP180 antibodies. Application of this assay as a routine diagnostic tool requires long-term storage of FL-BP180, which can result in substantial loss of expression. Here, we show that the disaccharide trehalose, a natural cryo- and lyoprotectant, is capable of preserving the FL-BP180 antigen expressed in Sf21 insect cells under various (dry) storage conditions including 40 degrees C, room temperature (RT), 4-8, -20, and -80 degrees C. The protective effect was dose-dependent reaching a maximum at about 200 mM trehalose. Trehalose was superior to other sugars or conventional cryoprotective agents (e.g. sucrose, myo-inositol, DMSO) in preventing greatly reduced antigen expression. Trehalose conserved the expression of both extra- and intracellular epitopes of FL-BP180. Interestingly, protection of the intracellular domain was only observed when trehalose was introduced into the cytosol. Trehalose significantly prolonged the storage time of FL-BP180 expressed in Sf21 insect cells, thus permitting the routine use of the IF assay in clinics for the detection of serum antibodies. The method described here has potential applications for the preservation of other transmembrane proteins.

Abstract
BACKGROUND The cryopreservation of HPCs in DMSO has been practiced by cord blood (CB) banks worldwide. Inevitably, some detriment to biologic function occurs as the result of freezing injuries and DMSO toxicity. Trehalose, a disaccharide, is a natural cryoprotectant in organisms capable of surviving extreme dehydration and cold. The objective of this study was to establish the cryopreservation of CB under preclinical conditions using trehalose as a supplement to DMSO. STUDY DESIGN AND METHODS In a preclinical protocol, the effects of 5-percent trehalose with 10-percent DMSO or 5-percent DMSO on the cryopreservation of CB MNCs or nucleated cells (NCs) were further evaluated. The read-out system consisted of a panel of HPCs: early progenitors (CFU-GEMM, long-term culture-initiating cells [LTC-IC]) and committed progenitors (CFU-GM, CFU/BFU-E, CFU-megakaryocyte [CFU-MK]). The homing and engraftment capacity of these cells were assessed in nonobese diabetic (NOD)-SCID mice. RESULTS Trehalose increased the recoveries of CFU-GM, CFU/BFU-E, CFU-GEMM, and LTC-IC by over 7.25 percent (mean), 11.9 percent, 19.2 percent, and 12.9 percent, respectively, when compared with those in paired CB samples cryopreserved in 10-percent DMSO. Freezing and thawing reduced the yields of CFU-MK by 35.5 percent (mean) and 28.4 percent in MNC and NC samples, respectively, and the inclusion of 5-percent trehalose significantly retrieved these progenitor cells to over 90 percent of fresh samples. The improved recovery of functional HPLs was reflected by their multilineage engraftment in NOD-SCID mice. CONCLUSION Trehalose at 5 percent significantly ameliorates the cryopreservation of CB progenitor cells at a preclinical protocol. The increased recoveries of these cells might potentially improve the engraftment outcomes of CB transplants.

Abstract
One mode of action of protectants in the storage of biological materials is by promoting the formation of a vitrified state on cooling or drying. In the case of preservation by drying, the glassy material comprises a low water content mixture of protectant and organic material. The protectant must on drying form a glassy state of glass transition temperature (T(g)) above the desired storage temperature. However, in some applications it must also be easily transported through cell membranes and this restricts the choice to a relatively limited number of small molecules, which typically exhibit very low glass transition temperatures. In this work we describe a self-polymerizing protectant comprising an inorganic salt and a small hydroxy functional molecule such as glycerol. This forms co-ordinate polymer chains of high T(g) on drying but rapidly depolymerizes into the original components on rehydration. The polymerization process is general for polyhydroxy compounds including glucose and related compounds.

Abstract
In this study, we tested a non-permeating cryoprotectant, trehalose, in combination with dimethyl sulfoxide (Me(2)SO) in the cryopreservation of human fetal skin and compared it to Me(2)SO and glycerol, protocols that are routinely used by skin banks. The viability of fetal skin from four groups (fresh, and cryopreserved with glycerol, Me(2)SO, or trehalose/Me(2)SO) were evaluated using an in vitro membrane integrity assay and by transplantation to immunodeficient mice. The membrane integrity assay showed a 90% integrity in fresh, unfrozen fetal skin. The number of intact cells dropped to 23 and 44% in fetal skin cryopreserved with glycerol and Me(2)SO, respectively. When trehalose was added to the cryopreservation medium containing Me(2)SO, the membrane integrity rose to 65%. When transplanted to immunodeficient mice, fetal skin cryopreserved with trehalose/Me(2)SO showed a graft performance indistinguishable from fresh unfrozen fetal skin and strikingly better graft take than that of fetal skin cryopreserved with Me(2)SO or glycerol only. These results suggest that cryopreservation protocols routinely used the skin banks can be improved by combining sugars such as trehalose with a permeating cryoprotectant.

Abstract
Ichthyophthirius multifiliis is an obligate protozoan parasite of freshwater fishes that has a complex developmental cycle. It has not been successfully cryopreserved, so management studies are restricted to parasites obtained during outbreaks or perpetuated by passage in live fishes. To overcome this serious limitation, free-swimming I. multifiliis parasites were tested in a cryopreservation protocol routinely used for a related ciliate, Tetrahymena. In this protocol, I. multifiliis theronts retained infectivity for 3 days, although the protocol itself was ultimately lethal. Exposure of I. multifiliis and Tetrahymena thermophila to a battery of media and cryopreservative reagents showed that I. multifiliis was less hardy than T. thermophila and likely had significant biological and cytoskeletal differences. No combination of reagents, media, freezing rates, or dilution media permitted cryopreservation of I. multifiliis parasites that could then undergo development or infect fish. However, a vitrification protocol was formulated using Ficoll, 1,2-propanediol, and N,N-dimethylacetamide from which intact cryopreserved theronts with some motility were recovered. Understanding the effects of these reagents may lead to both a cryopreservation method for I. multifiliis and to improved understanding of the biology of ciliates.

Abstract
BACKGROUND Electropermeabilization is widely used for introduction of DNA and other foreign molecules into eukaryotic cells. However, conditions yielding the greatest molecule uptake and gene expression can result in low cell survival. In this study, we assessed the efficiency of trehalose for enhancing cell viability after excessive electropermeabilization. This disaccharide was chosen because of its capability of stabilizing cell membranes under various stressful conditions, such as dehydration and freezing. MATERIALS AND METHODS Various mammalian cell lines were electropermeabilized by single exponentially decaying electric pulses of few kV/cm strength and of several-microsecond duration. Propidium iodide (PI) and a plasmid encoding green fluorescent protein (GFP), respectively, served as reporter molecules. The effects of trehalose on PI-uptake, GFP gene expression, transfection yield, and short- and long-term viability were analyzed by flow cytometry and electronic cell counting. RESULTS The substitution of inositol by trehalose in pulse media protected cells against field-induced cell lysis. The protection effect saturated at about 40-50 mM trehalose. Transfection yield and gene expression were not significantly affected by trehalose. But the transfection efficiency was generally higher in the presence of trehalose, mainly because of the increased cell survival. CONCLUSIONS We demonstrated that trehalose-substituted media are superior to standard trehalose-free pulse media for improving cell survival and achieving higher electrotransfection efficiency.

Abstract
Cord blood (CB) and fetal liver (FL) cells are two alternative sources of human hematopoietic stem cells. Optimization of cryopreservation protocols is an important aspect in the banking of these tissues. Out of the multiple factors responsible for cryodamage of cells, membrane leakage and oxygen free-radical generation have been shown to contribute substantially toward the process. We have studied the effect of certain additives, like membrane stabilizers and bioantioxidants, to the conventional freezing medium on viability, nucleated cell recovery, and clonogenic potential of frozen cells. Our results show that trehalose, a membrane stabilizer, when used in combination with 10% dimethyl sulfoxide (DMSO) affords better cryoprotection as evidenced by significantly increased colony formation as compared to 10% DMSO alone. The cryoprotection afforded by trehalose persists at least for 1.5 years and there is no bias toward protection of a particular lineage. We also found that this increased cryoprotective effect of trehalose is seen both at -196 degrees C and -80 degrees C storage temperatures. Addition of taurine, an amino acid, another membrane stabilizer, and a natural cryoprotectant to the traditional freezing medium also results in beneficial effect. Of the three bioantioxidants tested, i.e., ascorbic acid, alpha-tocopherol acetate, and catalase, catalase shows maximum cryoprotective effect both at -196 degrees C and at -80 degrees C. Because the mode of cryoprotective action of catalase and trehalose are totally different, we tried a combination of these two compounds along with 10% DMSO. At -196 degrees C the protection afforded by the combination was significantly better than that afforded by individual components. At -80 degrees C, however, the combination did not give any added protection as compared to the individual single additives, although it was significantly better than 10% DMSO alone. These results indicate that the addition of membrane stabilizers and antioxidants to the conventional freezing medium may help to improve post thaw recovery of hematopoietic cells.
