Abstract
Hematopoietic stem cells (HSCs) and their development are one of the most widely studied model systems in mammals. In adults, HSCs are predominantly found in the bone marrow, from where they maintain homeostasis. Besides bone marrow and mobilized peripheral blood, cord blood is also being used as an alternate allogenic source of transplantable HSCs. HSCs from both autologous and allogenic sources are being applied for the treatment of various conditions like blood cancers, anemia, etc. HSCs can further differentiate to mature blood cells. Differentiation process of HSCs is being extensively studied so as to obtain a large number of pure populations of various differentiated cells in vitro so that they can be taken up for clinical trials. The ability to generate sufficient quantity of clinical-grade specialized blood cells in vitro would take the field of hematology a step ahead in translational medicine.

Cryobiology 2021; 98:152-163. [PMID: 33253747 DOI: 10.1016/j.cryobiol.2020.11.009] [Citation(s) in RCA: 18] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/12/2020] [Revised: 11/06/2020] [Accepted: 11/06/2020] [Indexed: 02/08/2023]
Abstract
The multitude of clinical trials using mesenchymal stromal cells (MSCs) has underscored their significance as a promising cell source for regenerative therapies. Most studies have however shown that MSCs get entrapped into the microvasculature of lungs, liver and spleen. In addition to intercellular communication, MSCs exert their effects in a paracrine manner by secretion of extracellular vesicles (EVs). The therapeutic effects of MSC-derived EVs have been examined in several diseases such as hepatic failure, liver injury, hematopoiesis etc. Therefore, optimization of cryopreservation strategies for the long-term storage of functional EVs could help in the development of off-the-shelf biologics. The aim of this study was to develop an optimal cryopreservation strategy for the efficient storage of both types of EVs - Microvesicles (MVs) and exosomes, independently, and to further examine the effect of the cryopreserved EVs on the ex vivo expansion of HSCs. MVs and exosomes were separately cryopreserved at different temperatures using PBS or PBS supplemented with trehalose (pTRE), and these cryopreserved EVs were then assessed for their functionality after revival. We found that addition of trehalose during cryopreservation helped in maintaining the morphology and functionality of the EVs, as assessed by their HSC-supportive potential, ability to expand phenotypically defined HSCs and ability to maintain the chemotactic migration potential of the HSCs co-cultured with them. This strategy could prove to be beneficial for facilitating the use of EVs as cell-free ready-to-use biologics for the ex vivo expansion of HSCs and in regenerative medicine.

Abstract
Acute myeloid leukemia (AML) is an aggressive blood cancer resulting in accumulation of immature, dysfunctional blood cells in the bone marrow. Changes in cell metabolism are features of many cancers, including AML and this may be exploited as a therapeutic target. In this study we investigated the in vitro antileukemic effects of seven metabolic inhibitors that target different metabolic pathways. The metabolic inhibitors were tested on AML cells derived from 81 patients using proliferation and viability assays; we also compared global gene expression and proteomic profiles for various patient subsets. Metformin, 2DG, 6AN, BPTES and ST1326 had strong antiproliferative and proapoptotic effects for most patients, whereas lonidamine and AZD3965 had an effect only for a minority. Antiproliferative effects on AML cells were additive when combined with the chemotherapeutic agent AraC. Using unsupervised hierarchical clustering, we identified a strong antiproliferative effect on AML cells after treatment with metabolic inhibitors for a subset of 29 patients. Gene expression and proteomic studies suggested that this subset was characterized by altered metabolic and transcriptional regulation. In addition, the Bcl-2 inhibitor venetoclax, in combination with 2DG or 6AN, increased the antiproliferative effects of these metabolic inhibitors on AML cells. Therapeutic targeting of cellular metabolism may have potential in AML, but the optimal strategy will likely differ between patients.

Abstract
BACKGROUND Platelet engraftment following cord blood (CB) transplantation remains a significant hurdle to this day. The uncontrolled growth of ice, a process referred to as ice recrystallization, is one of several mechanisms that lead to cell loss and decreased potency during freezing and thawing. We hypothesized that reducing cell damage induced by ice recrystallization in CB units (CBUs) would reduce losses of stem and progenitor cells and therefore improve engraftment. We previously demonstrated that the ice recrystallization inhibitor (IRI) N-(2-fluorophenyl)-D-gluconamide (IRI 2) increases the postthaw recovery of CB progenitors. Herein, we set out to ascertain whether IRI 2 can enhance platelet and bone marrow engraftment activity of hematopoietic stem cells (HSCs) in cryopreserved CBUs using a serial transplantation model. STUDY DESIGN AND METHODS CBUs were processed following standard volume/red blood cell reduction procedure and portions frozen with dimethyl sulfoxide (DMSO) supplemented or not with IRI 2. Thawed CB samples were serially transplanted into immunodeficient mice. RESULTS Our results show that supplementation of DMSO with IRI 2 had several beneficial effects. Specifically, higher levels of human platelets were observed in the peripheral blood (p < 0.05; n = 4) upon transplant of CBUs preserved with the IRIs. In addition, human BM chimerism and the number of human CFU progenitors in the bone marrow were superior in IRI 2 recipients compared to DMSO recipients. Moreover, IRI 2 had no negative impact on the multilineage differentiation and self-renewal activities of HSCs. DISCUSSION Taken together, these results demonstrate that supplementation of a hematopoietic graft with IRI can improve the postthaw engraftment activities of HSCs.

Abstract
Abstract
Use of cold for preservation of biological materials, avoidance of food spoilage and to manage a variety of medical conditions has been known for centuries. The cryobiological science justified these applications in the 1960s increasing their use in expanding global activities. However, the engineering and technological aspects associated with cryobiology can be expensive and this raises questions about the abilities of resource-restricted low and middle income countries (LMICs) to benefit from the advances. This review was undertaken to understand where or how access to cryobiological advances currently exist and the constraints on their usage. The subject areas investigated were based on themes which commonly appear in the journal Cryobiology. This led in the final analysis for separating the review into two parts, with the first part dealing with cold applied for biopreservation of living cells and tissues in science, health care and agriculture, and the second part dealing with cold destruction of tissues in medicine. The limitations of the approaches used are recognized, but as a first attempt to address these topics surrounding access to cryobiology in LMICs, the review should pave the way for future more subject-specific assessments of the true global uptake of the benefits of cryobiology.

Abstract
Cryopreservation has facilitated advancement of biological research by allowing the storage of cells over prolonged periods of time. While cryopreservation at extremely low temperatures would render cells metabolically inactive, cells suffer insults during the freezing and thawing process. Among such insults, the generation of supra-physiological levels of reactive oxygen species (ROS) could impair cellular functions and survival. Antioxidants are potential additives that were reported to partially or completely reverse freeze-thaw stress-associated impairments. This review aims to discuss the potential sources of cryopreservation-induced ROS and the effectiveness of antioxidant administration when used individually or in combination.

Abstract
The phosphatidylinositol 3-kinase (PI3K)-Akt-mechanistic target of rapamycin (mTOR) pathway is constitutively activated in human acute myeloid leukemia (AML) cells and is regarded as a possible therapeutic target. Insulin is an agonist of this pathway and a growth factor for AML cells. We characterized the effect of insulin on the phosphorylation of 10 mediators in the main track of the PI3K-Akt-mTOR pathway in AML cells from 76 consecutive patients. The overall results showed that insulin significantly increased the phosphorylation of all investigated mediators. However, insulin effects on the pathway activation profile varied among patients, and increased phosphorylation in all mediators was observed only in a minority of patients; in other patients, insulin had divergent effects. Global gene expression profiling and proteomic/phosphoproteomic comparisons suggested that AML cells from these two patient subsets differed with regard to AML cell differentiation, transcriptional regulation, RNA metabolism, and cellular metabolism. Strong insulin-induced phosphorylation was associated with weakened antiproliferative effects of metabolic inhibitors. PI3K, Akt, and mTOR inhibitors also caused divergent effects on the overall pathway phosphorylation profile in the presence of insulin, although PI3K and Akt inhibition caused a general reduction in Akt pT308 and 4EBP1 pT36/pT45 phosphorylation. For Akt inhibition, the phosphorylation of upstream mediators was generally increased or unaltered. In contrast, mTOR inhibition reduced mTOR pS2448 and S6 pS244 phosphorylation but increased Akt pT308 phosphorylation. In conclusion, the effects of both insulin and PI3K-Akt-mTOR inhibitors differ between AML patient subsets, and differences in insulin responsiveness are associated with differential susceptibility to metabolic targeting.

Abstract
BACKGROUND Dendritic cell (DC) vaccination involves administration of multiple doses. Cryopreservation of tumor antigen-pulsed DCs can provide a ready to use vaccine source and eliminate the need of frequent withdrawal of the patient's blood for vaccine preparation. The aim of this study was to assess the effect of addition of trehalose in the freezing medium on the recovery of DCs after cryopreservation. STUDY DESIGN AND METHODS DCs were generated from mononuclear cells from apheresis samples of healthy donors. For long-term storage of 6 months, cells were frozen with a rate-controlled programmable freezer and stored in liquid nitrogen. For short-term storage of 1 month, cells were frozen and stored at -80°C. DCs frozen with Iscove's Modified Dulbecco's Medium + 10% dimethyl sulfoxide + 20% fetal bovine serum served as the control group, while the test group was additionally supplemented with 50 μg/mL of trehalose. After revival of control and test DCs, they were assessed for viability, morphology, phenotype, and functions. RESULTS The addition of trehalose to the conventional freezing medium helped to preserve the viability and functionality of DCs better than dimethyl sulfoxide alone in both long- and short-term cryopreservation. Trehalose also protected the mitochondrial membrane potential and cytoskeleton integrity of DCs, which are necessary for their functionality. Mediators of the intrinsic apoptotic pathway like Caspase-9 and Bim-1 were found to be low in the test. CONCLUSION Supplementation of conventional freezing medium with trehalose results in better quality of DCs revived after cryopreservation. This finding could help improve DC vaccine preparation for cancer immunotherapy.

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
The success of hematopoietic stem cell transplantation depends in part on the number and the quality of cells transplanted. Cryoinjuries during freezing and thawing reduce the ability of hematopoietic stem and progenitor cells (HSPCs) to proliferate and differentiate after thawing. Up to 20% of the patients undergoing umbilical cord blood (UCB) transplant experience delayed or failed engraftment, likely because of the inadequate hematopoietic potency of the unit. Therefore, the optimization of cryopreservation protocols, with an emphasis on the preservation of HSPCs, is an important issue. Current protocols typically utilize a 10% dimethyl sulfoxide cryoprotectant solution. This solution ensures 70-80% post-thaw cell viability by diluting intracellular solutes and maintaining the cell volume during cryopreservation. However, this solution fails to fully protect HSPCs, resulting in the loss of potency. Therefore, a new class of cryoprotectants (N-aryl-d-aldonamides) was designed and assessed for the ability to inhibit ice recrystallization and to protect HSPCs against cryoinjury. Several highly active ice recrystallization inhibitors were discovered. When used as additives to the conventional cryoprotectant solution, these nontoxic small molecules improved the preservation of functionally divergent hematopoietic progenitors in the colony-forming unit and long-term culture-initiating cell assays. By contrast, structurally similar compounds that did not inhibit ice recrystallization failed to improve the post-thaw recovery of myeloid progenitors. Together, these results demonstrate that the supplementation of cryopreservation solution with compounds capable of controlling ice recrystallization increases the post-thaw function and potency of HSPCs in UCB. This increase may translate into reduced risk of engraftment failure and allow for greater use of cryopreserved cord blood units.

Abstract
Background The limited cell dose in umbilical cord blood (UCB) necessitates ex vivo expansion of UCB. Further, the effective cryopreservation of these expanded cells is important in widening their use in the clinics. During cryopreservation, cells experience oxidative stress due to the generation of reactive oxygen species (ROS). Conditioned medium from mesenchymal stem cells (MSCs-CM) has been shown to alleviate the oxidative stress during wound healing, Alzheimer’s disease and ischemic disease. This premise prompted us to investigate the influence of MSCs-CM during cryopreservation of expanded UCB cells. Methodology/Principle findings CM-was collected from cord/placental MSCs(C-MSCs-CM, P-MSC-CM). UCB CD34+cells were expanded as suspension cultures in serum free medium containing cytokines for 10 days. Cells were frozen with/without C-MSCs-CM and or P-MSCs-CM in the conventional freezing medium containing 20%FCS +10%DMSO using a programmable freezer and stored in liquid nitrogen. Upon revival, cells frozen with MSCs-CM were found to be superior to cells frozen in conventional medium in terms of viability, CD34+content and clonogenecity. Priming of revived cells for 48 hrs with MSCs-CM further improved their transplantation ability, as compared to those cultured without MSCs-CM. P-MSCs-CM radically reduced the oxidative stress in cryopreserved cells, resulting in better post thaw functionality of CD34+ cells than with C-MSCs-CM. The observed cryoprotective effect of MSCs-CM was primarily due to anti-oxidative and anti-apoptotic properties of the MSCs-CM and not because of the exosomes secreted by them. Conclusions/Significance Our data suggest that MSCs-CM can serve as a valuable additive to the freezing or the priming medium for expanded UCB cells, which would increase their clinical applicability.

Abstract
Cryopreservation of spermatogonial stem cells is considered as a useful procedure for preserving fertility in children with testis cancer. SSCs were isolated from testes mice, and then antioxidant was added to the freezing medium. The Bax expression level in antioxidant groups was significantly (P ≤ 0.05) lower than the control group and a significant rise of Bcl2 expression was detected in the antioxidant groups. ROS production with antioxidant was significantly lower compared with the control group. Cryopreservation with the addition of the antioxidants can help increase the number of SSCs and improve the quality and viability of these cells after cryopreservation.

Abstract
Umbilical cord blood (UCB) is an extremely attractive source of stem cells for the treatment of various benign and malignant hematological and non-hematological disorders. To facilitate the preservation of these stem cells, 10 % dimethylsulfoxide (DMSO) is widely used as cryoprotectant in cord blood banks. But it is found to be toxic at this concentration with the result of serious side effects in recipients after infusion of DMSO-cryopreserved cells. Evaluation of viability and functionality of cryopreserved hematopoietic stem cells is needed with either inclusion of nontoxic additives alone or with reduced DMSO concentration. We assessed the post thawing viability of UCB stem cells in the freezing medium containing disaccharides (sucrose or trehalose) alone and in combination with reduced amount i.e. 2 % DMSO by trypan blue staining. The functionally active progenitor cells content of the optimized media was then evaluated and compared with 5% DMSO by a colony forming unit assay using methylcellulose based media. The freezing solution containing 0.2 M trehalose with 2 % DMSO came out to be superior in the evaluation of viability and generation of hematopoietic colonies of erythroid and myeloid lineage than 5 % DMSO alone. While the percentage of viability was lower than 2 % DMSO, as observed in the medium containing 0.2 M trehalose or sucrose alone, with poor outcome of generation of myeloid lineage based colonies. Our study results suggest that trehalose (0.2M) with the inclusion of reduced concentration of DMSO(2%) can better replace 5%DMSO rather than complete removal of DMSO from the freezing medium.

Abstract
INTRODUCTION Mesenchymal stem cells (MSC) and MSC-like cells hold great promise and offer many advantages for developing effective cellular therapeutics. Current trends indicate that the clinical application of MSC will continue to increase markedly. For clinical applications, large numbers of MSC are usually required, ideally in an off-the-shelf format, thus requiring extensive MSC expansion ex vivo and subsequent cryopreservation and banking. AREAS COVERED To exploit the full potential of MSC for cell-based therapies requires overcoming significant cell-manufacturing, banking and regulatory challenges. The current review will focus on the identification of optimal cell source for MSC, the techniques for production scale-up, cryopreservation and banking and the regulatory challenges involved. EXPERT OPINION There has been considerable success manufacturing and cryopreserving MSC at laboratory scale. Surprisingly little attention, however, has been given to translate these technologies to an industrial scale. The development of cost-effective advanced technologies for producing and cryopreserving commercial-scale MSC is important for successful clinical cell therapy.

Abstract
Endothelial progenitor cells (EPCs) provide a powerful option for therapeutic use in ischemic diseases. The cell therapy-induced vasculogenesis requires sufficient homogeneous cells, and cryopreservation is a prerequisite for long-term storage and quality assurance of EPCs. The aim of this study was to optimize cryopreservation protocols of EPCs derived from porcine bone marrow. Bone marrow-derived mononuclear cells (MNCs) were isolated by density centrifugation and differentiated into EPCs. The first passage EPCs were frozen by using different methodologies, and after cryopreservation the thawed cells were cultured to the fourth passage. The recovery efficiency and functions of these cells were evaluated by determination of cell viability, proliferation and migration. We found the optimal conditions for cryopreservation of EPCs as follows: (i) a cryopreservation medium consisting of 10% dimethylsulphoxide (DMSO) in combination with 50% fetal bovine serum (FBS); (ii) using a controlled freezing rate at 5°C/min; (iii) at an optimal density of 5×10⁶/ml for cryopreserved EPCs; (iv) a storage temperature of -156°C. Under these conditions we demonstrated that EPCs could be stored in mechanical freezer for up to 18 months after cryopreservation without losing their phenotypic characteristics and biological functions.

Abstract
Amniotic fluid-derived stem cells (AFSCs) are a potential cell source for therapeutic applications. They can be easily mass produced, cryopreserved and shipped to clinics for immediate use. However, one major obstacle to the manufacturing of clinical grade stem cells is the need for current good manufacturing practices for cryopreservation, storage, and distribution of these cells. Most current cryopreservation methods used for stem cells include the potentially toxic cryoprotectant (CPA) dimethylsulfoxide (Me(2)SO) in the presence of animal serum proteins that prevent direct use of these cells in human therapeutic applications. To avoid any potential cryoprotectant related complications, it will be essential to develop non-toxic CPAs or reduce CPA concentration in the freezing media used. In this study, we assessed the use of disaccharides, antioxidants and caspase inhibitors for cryopreservation of AFSCs in combination with a reduced concentration of Me(2)SO. The thawed cells were tested for viability with MTT assays and a growth curve was created to measure population doubling time. In addition, we performed flow cytometry analysis for cell surface antigens, RT-PCR for mRNA expression of stem cell markers, and assays to determine the myogenic differentiation potential of the cells. A statistically significant (p<0.05) increase in post-thawed cell viability in solutions containing trehalose, catalase and (Z)VAD-fmk with 5% Me(2)SO was observed. The solutions containing trehalose and catalase with 5% or 2.5% (v/v) Me(2)SO produced results similar to those for the control (10% (v/v) Me(2)SO and 30% FBS) in terms of culture growth, expression of cell surface antigens and mRNA expression of stem cell markers in AFSCs cryopreserved for a minimum of 3 weeks. Thus, AFSCs can be cryopreserved with 1/4 the standard Me(2)SO concentration with the addition of disaccharides, antioxidants and caspase inhibitors. The use of Me(2)SO at low concentrations in cell freezing solutions may support the development of clinical trials of AFSCs.

Abstract
Cryopreservation of human umbilical cord blood (UCB) typically involves the cryoprotectant dimethylsulfoxide (DMSO), however, infusional toxicity and reductions in cell viability remain a concern. Ice recrystallization (IR) is an important source of cryopreservation-induced cellular injury and limits the stem cell dose in UCB units. Carbohydrates have wide-ranging intrinsic IR inhibition (IRI) activity related to structural properties. We investigated the impact of carbohydrate IRI on cell viability, induction of apoptosis and hematopoietic progenitor function in cryopreserved UCB. Mononuclear cells (MNCs) from UCB were cryopreserved in storage media containing specific carbohydrates (200mM) and compared to 5% DMSO. Samples were analyzed under conditions of high IR ('slow' thaw) and low IR ('fast' thaw). Thawed samples were analyzed for viability and apoptosis by flow cytometry and hematopoietic function using colony-forming unit (CFU) assays. IRI of carbohydrate solutions was determined using the 'splat cooling' assay. Greater IRI capacity of carbohydrates correlated with increased yield of viable MNCs (r(2)=0.92, p=0.004) and CD34(+) cells (r(2)=0.96, p=0.019) after thawing under conditions of high IR. The correlations were less apparent under conditions of low IR. Carbohydrates with greater IRI modulate the induction of early apoptosis during thawing, especially in CD34+ cells (r(2)=0.96, p=0.0001) as compared to total mononuclear cells (p=0.006), and preserve CFU capacity in vitro (r(2)=0.92, p=<0.0001). Our results suggest that carbohydrates with potent IRI increase the yield of non-apoptotic and functional hematopoietic progenitors and provide a foundation for the development of novel synthetic carbohydrates with enhanced IRI properties to improve cryopreservation of UCB.

Abstract
Transplantation using hematopoietic stem cells from umbilical cord blood (UCB) is a life-saving treatment option for patients with select oncologic diseases, immunologic diseases, bone marrow failure, and others. Often this transplant modality requires cryopreservation and storage of hematopoietic stem cells (HSC), which need to remain cryopreserved in UCB banks for possible future use. The most widely used cryoprotectant is dimethylsulfoxide (Me(2)SO), but at 37 degrees C, it is toxic to cells and for patients, infusion of cryopreserved HSC with Me(2)SO has been associated with side effects. Freezing of cells leads to chemical change of cellular components, which results in physical disruption. Reactive oxygen species (ROS) generation also has been implicated as cause of damage to cells during freezing. We assessed the ability of two bioantioxidants and two disaccharides, to enhance the cryopreservation of UCB. UCB was processed and subjected to cryopreservation in solutions containing different concentrations of Me(2)SO, bioantioxidants and disaccharides. Samples were thawed, and then analysed by: flow cytometry analysis, CFU assay and MTT viability assay. In this study, our analyses showed that antioxidants, principally catalase, performed greater preservation of: CD34+ cells, CD123+ cells, colony-forming units and cell viability, all post-thawed, compared with the standard solution of cryopreservation. Our present studies show that the addition of catalase improved the cryopreservation outcome. Catalase may act on reducing levels of ROS, further indicating that accumulation of free radicals indeed leads to death in cryopreserved hematopoietic cells.

Abstract
A beluga (Delphinapterus leucas) sperm preservation method was developed for use in genome banking and AI. In Study 1, glycerol-based cryodiluents (modified BF5F and modified Platz Diluent Variant (PDV)) were unable to maintain adequate progressive motility using straws (fast and slow freezing rate (FR)) or pellets (slow FR). Neither freezing method nor FR affected in vitro sperm characteristics (P > 0.05), but retention of prefreeze progressive motility following thawing was greater (P < 0.05) for BF5F (21%) than PDV (15%). In Study 2, examining the effects of straw freeze–thawing using BF5F with glycerol (1 and 3%, v/v) or trehalose (46 and 91 mM) on sperm characteristics, samples cryopreserved in trehalose exhibited superior (P < 0.05) in vitro parameters compared with their glycerol-treated counterparts. In Study 3, compared with a straw method, directional freezing using 91 mM trehalose enhanced (P < 0.05) sperm characteristics, with samples retaining 38%, 75% and 61% of their prefreeze progressive motility, curvilinear velocity and viability, respectively. A higher (P < 0.05) proportion of motile spermatozoa displayed rapid velocity after directional (21 ± 1%) compared with straw (12 ± 3%) freezing. Systematic development of a cryodiluent and the use of directional freezing resulted in beluga spermatozoa exhibiting adequate post-thaw quality for genome banking and use in AI.

Abstract
BACKGROUND This study examined ex vivo expansion of bone marrow-derived endothelial progenitor cell (EPC) from cryopreserved bone marrow-derived mononuclear cells, and evaluated proliferation and migration function of the cryopreserved EPC (Cryo-EPC). METHODS Bone marrow samples were taken from swine iliac bone (n = 6). Isolated bone marrow-derived mononuclear cells were cultured or cryopreserved at -80 degrees C for 2 to 3 months. After cell culture for 4 days, attached cells, EPCs with or without cryopreservation, were collected. Direct fluorescent staining by acetylated low-density lipoprotein, isolectin B4, and 4',6-diamidino-2-phenylindole were performed to confirm the attached cells as EPC. Endothelial progenitor cell proliferation by vascular endothelial growth factor was evaluated by the tetrazolium method. Endothelial progenitor cell migration in response to stromal-derived factor-1alpha was also evaluated by using a Boyden chamber assay. RESULTS The percentage of cells positively stained by direct fluorescent staining by acetylated low-density lipoprotein and isolectin B4 was similar between fresh and Cryo-EPC (EPC = 96.0 +/- 0.42 versus Cryo-EPC = 95.2 +/- 1.2; p = 0.21). Vascular endothelial growth factor increased proliferation activity in fresh and Cryo-EPC (p < 0.01). Stromal-derived factor-1alpha increased migration activity in fresh and Cryo-EPC (p < 0.01). There was no difference in proliferation and migration activity between fresh and Cryo-EPC. CONCLUSIONS Ex vivo expansion by cell culture was a useful method for collection of bone marrow-derived EPC from cryopreserved mononuclear cells. Proliferation and migration function of EPC is preserved after cryopreservation.

Abstract
Antioxidants, dimethylsulfoxide (DMSO) and dimethylthiourea (DMTU), at concentrations not affecting the viability of blood cells (haemocytes) from the larval stage of 3 lepidopteran insects - Galleria mellonella, Lymantria dispar, and Malacosoma disstria - differed in their influence on the innate binding of haemocytes to glass, bacteria to haemocytes, and on humoral responses to alien materials. In vitro DMSO had little effect, whereas DMTU substantially impaired the adhesion of the haemocyte types, the plasmatocytes and granular cells, to slides as well as the attachment of Bacillus subtilis to these haemocytes. Although both antioxidants increased lysozyme and phenoloxidase activities, there was no correlation of enzyme activity and haemocyte adhesion responses, possibly reflecting sequestered radicals. Nitric oxide and hydroxyl radicals offset the DMTU effect. In the absence of antioxidants, inactivate protein kinases A (PKA) and C (PKC) enhanced haemocyte aggregation. In general, DMSO, as opposed to DMTU, did not alter the effects of PKA and PKC activators and inhibitors on haemocyte aggregation or of PKC and PKA activities. High concentrations of DMSO and all levels of DMTU, although inhibiting PKA and PKC, inhibited haemocyte adhesion to slides. Comparable results occurred for DMTU-treated haemocytes incubated with B. subtilis. In vivo DMSO, unlike DMTU, did not impair plasmatocyte or granular cell responses to foreign materials, including bacterial removal from the haemolymph and nodulation.

Abstract
Previous studies have demonstrated that ice/cell interaction influences post thaw viability and specific cryoprotective agents can affect those interactions. Trehalose, a disaccharide, has been shown to have a protective benefit during conventional slow freezing. Existing theories have been put forth to explain the protective benefit of trehalose during desiccation and vitrification, but these theories do not explain the protective benefit observed during conventional freezing protocols. The overall objective of this investigation was to characterize cell/ice interactions in the presence of trehalose using non-planar freezing conditions. To that end, lymphoblasts suspended in phosphate buffered saline solution with various levels of trehalose (0, 10, 100, and 300 mM) were frozen on a directional solidification stage. The partitioning of cells into the interdendritic space or engulfment by an advancing dendrite was determined as a function of velocity and solution composition. For a given temperature gradient, the fraction of cells entrapped into the interdendritic region increased with increasing velocity. With small additions of trehalose (10 mM), the velocity at which cells were entrapped in the interdendritic region increased. At high trehalose concentrations (100, 300 mM), interface morphology was significantly different and cells were engulfed by the advancing interface. Dehydration of cells in the region shortly before and after the interface was significant and depended upon of the type of interaction experienced by the cell (entrapped vs. engulfed). These studies suggest that one potential mechanism for the action of trehalose involves changing the ice/cell interactions during conventional slow freezing.

Abstract
Tissue engineering is a multidisciplinary field that combines engineering, physical sciences, biology, and medicine to restore or replace tissues and organs functions. In this review, enabling tools for tissue engineering are discussed in the context of four key areas or pillars: prediction, production, performance, and preservation. Prediction refers to the computational modeling where the ability to simulate cellular behavior in complex three-dimensional environments will be essential for design of tissues. Production refer imaging modalities that allow high resolution, non-invasive monitoring of the development and incorporation of tissue engineered constructs. Lastly, preservation includes biochemical tools that permit cryopreservation, vitrification, and freeze-drying of cells and tissues. Recent progress and future perspectives for development in each of these key areas are presented.

Abstract
Recent studies illustrate the potential for improving the cryopreservation of stem cells. Reduced DMSO concentrations in the cryopreservation medium, post thaw washing of cells and increased cell concentration have been actively studied. Standardization of cell processing has led to the study of liquid storage prior to cryopreservation, validation of mechanical (uncontrolled rate freezing) freezing, and cryopreservation bag failure. Finally, the need for the systematic study and optimization of preservation processes has not been fulfilled. As the sources and applications of stem cells (hematopoietic and non-hematopoietic) continue to be developed, the need for effective preservation methods will only grow.

Abstract
The bioinert materials on which cells do not proliferate, differentiate, nor de-differentiate should be useful for the culture and preservation of stem cells. The Pluronic F127, a triblock copolymer of ethylene oxide, and propylene oxide was activated using carbonyldiimidazole (CDI), and CDI-activated Pluronic was subsequently immobilized on the surface of a lysine-coated polystyrene tissue culture flask. The morphology of fibroblasts (L929 cells) on the Pluronic-immobilized flask was spherical, and did not show spreading behavior. This observation indicates that L929 cells on the Pluronic-immobilized flask were cultured in a bioinert environment. The expression ratio of surface markers on hematopoietic stem cells (CD34 and CD133) cultured in the Pluronic-immobilized flask was significantly higher than that in polystyrene tissue culture flask and commercially available bioinert flask (i.e., low cell binding cultureware). This is caused by the existence of hydrophilic segments of Pluronic F127 on the Pluronic-immobilized flask.

Abstract
BACKGROUND Our previous in vitro work has shown the usefulness of membrane stabilizers and antioxidants as additives in conventional freezing medium to freeze mouse and human hematopoietic cells. The present work was carried out using murine model to test the in vivo engraftment ability of mouse bone marrow frozen with (test cells) or without (control cells) addition of a combination of trehalose and catalase in the medium containing 10% dimethyl sulfoxide (DMSO). METHODS Viability, nucleated cell recovery, and progenitor content of revived cells were measured. Freezing efficacy was tested by in vivo assays like colony forming unit-spleen (CFU-S), pre-CFU-S, and short-term engraftment of frozen marrow in irradiated mice. Long-term engraftment ability of frozen marrow was assessed using a Ly5.1-Ly 5.2 chimera model. Levels of apoptosis and reactive oxygen species (ROS) generated in revived cells were estimated. The former by Annnexin V, TUNEL, and DNA laddering and the latter by DCFH-DA probe. RESULTS Our results show that the combination of catalase and trehalose with 10% DMSO improves freezing efficacy not only in terms of viability, cell recovery, and progenitor content but also by in vivo assays like CFU-S, pre-CFU-S, and short- and long-term engraftment. Both the level of apoptosis and ROS generation were considerably reduced in test set as compared to control set. CONCLUSIONS We conclude that inclusion of a combination of trehalose and catalase in conventional freezing medium leads to enhanced engraftment potential of cryopreserved mouse bone marrow cells probably by preventing apoptotic cell death. Our observation using animal model may have significant clinical implications.
