Impact of cryopreservation on viability, gene expression and function of enteric nervous system derived neurospheres. Front Cell Dev Biol 2023; 11:1196472. [PMID: 37377739 PMCID: PMC10291272 DOI: 10.3389/fcell.2023.1196472] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2023] [Accepted: 05/31/2023] [Indexed: 06/29/2023] Open
Abstract
Introduction: Impairment of both the central and peripheral nervous system is a major cause of mortality and disability. It varies from an affection of the brain to various types of enteric dysganglionosis. Congenital enteric dysganglionosis is characterized by the local absence of intrinsic innervation due to deficits in either migration, proliferation or differentiation of neural stem cells. Despite surgery, children's quality of life is reduced. Neural stem cell transplantation seems a promising therapeutic approach, requiring huge amounts of cells and multiple approaches to fully colonize the diseased areas completely. A combination of successful expansion and storage of neural stem cells is needed until a sufficient amount of cells is generated. This must be combined with suitable cell transplantation strategies, that cover all the area affected. Cryopreservation provides the possibility to store cells for long time, unfortunately with side effects, i.e., upon vitality. Methods: In this study we investigate the impact of different freezing and thawing protocols (M1-M4) upon enteric neural stem cell survival, protein and gene expression, and cell function. Results: Freezing enteric nervous system derived neurospheres (ENSdN) following slow-freezing protocols (M1-3) resulted in higher survival rates than flash-freezing (M4). RNA expression profiles were least affected by freezing protocols M1/2, whereas the protein expression of ENSdN remained unchanged after treatment with protocol M1 only. Cells treated with the most promising freezing protocol (M1, slow freezing in fetal calf serum plus 10% DMSO) were subsequently investigated using single-cell calcium imaging. Freezing of ENSdN did not alter the increase in intracellular calcium in response to a specific set of stimuli. Single cells could be assigned to functional subgroups according to response patterns and a significant shift towards cells responding to nicotine was observed after freezing. Discussion: The results demonstrate that cryopreservation of ENSdN is possible with reduced viability, only slight changes in protein/gene expression patterns and without an impact on the neuronal function of different enteric nervous system cell subtypes, with the exception of a subtle upregulation of cells expressing nicotinergic acetylcholine receptors. In summary, cryopreservation presents a good method to store sufficient amounts of enteric neural stem cells without neuronal impairment, in order to enable subsequent transplantation of cells into compromised tissues.

Abstract
Differentiation of human induced pluripotent stem cells (hiPSCs) generates cell phenotypes valuable for cell therapy and personalized medicine. Successful translation of these hiPSC-derived therapeutic products will rely upon effective cryopreservation at multiple stages of the manufacturing cycle. From the perspective of cryobiology, we attempted to understand how the challenge of cryopreservation evolves between cell phenotypes along an hiPSC-to-sensory neuron differentiation trajectory. Cells were cultivated at three different stages to represent intermediate, differentiated, and matured cell products. All cell stages remained ≥90% viable in a dimethyl sulfoxide (DMSO)-free formulation but suffered ≥50% loss in DMSO before freezing. Raman spectroscopy revealed higher sensitivity to undercooling in hiPSC-derived neuronal cells with lower membrane fluidity and higher sensitivity to suboptimal cooling rates in stem cell developmental stages with larger cell bodies. Highly viable and functional sensory neurons were obtained following DMSO-free cryopreservation. Our study also demonstrated that dissociating adherent cultures plays an important role in the ability of cells to survive and function after cryopreservation.

Abstract
Human induced pluripotent stem cells (hiPSCs) have the properties of differentiation potential and unlimited self-renewal. Developing efficient and highly safe methods to preserve hiPSCs is important due to they have demonstrated tremendous promise in disease etiology, drug discovery, and regenerative medicine applications. Traditionally, open systems for cell cryopreservation, such as conventional slow freezing and vitrification methods, were widespread application in the storage and transportation of hiPSCs. However, these two methods have such problems of low recovery rate and the risk of cross-contamination. Recently, closed systems for cell cryopreservation, such as CryoLogic Vitrification Method (CVM), were introduced to store and transport embryos. In this study, we developed a new friendly CVM by loading a small piece of hiPSCs colonies in the vitrification solution to the hook of Fiberplug to increase the cooling rate. To warm them, the CVM Fiberplug was immersed directly in a 37 °C warming solution for 1 min, and hiPSCs were then transferred to mTeSR1 medium. The result revealed that the new CVM had a high recovery rate and maintained the stemness and differentiation potential of hiPSCs. Our new CVM not only provide a safe way for hiPSCs preservation but also has a high survival rate in the storage of hiPSCs.

Abstract
Human induced pluripotent stem cells (hiPSCs) are an important cell source for regenerative medicine products. Effective methods of preservation are critical to their clinical and commercial applications. The use of a dimethyl sulfoxide (DMSO)-free solution containing all non-toxic molecules offers an effective alternative to the conventional DMSO and alleviates pain points associated with the use of DMSO in the cryopreservation of hiPSCs. Both hiPSCs and cells differentiated from them are commonly multicellular systems, which are more sensitive to stresses of freezing and thawing than single cells. In this investigation, low-temperature Raman spectroscopy visualized freezing behaviors of hiPSC aggregates in different solutions. These aggregates exhibited sensitivity to undercooling in DMSO-containing solutions. We demonstrated the ability to replace DMSO with non-toxic molecules, improve post-thaw cell survival, and reduce sensitivity to undercooling. An accelerated optimization process capitalized on the positive synergy among multiple DMSO-free molecules, which acted in concert to influence ice formation and protect cells during freezing and thawing. A differential evolution algorithm was used to optimize the multi-variable, DMSO-free preservation protocol in 8 experiments. hiPSC aggregates frozen in the optimized solution did not exhibit the same sensitivity to undercooling as those frozen in non-optimized solutions or DMSO, indicating superior adaptability of the optimized solution to different freezing modalities and unplanned deviations. This investigation shows the importance of optimization, explains the mechanisms and advantages of a DMSO-free solution, and enables not only improved cryopreservation of hiPSCs but potentially other cell types for translational regenerative medicine.

Abstract
Reports on the vitrification of somatic cells are scarce. Here, we show that Leydig cells (murine cell line TM3) could be successfully vitrified by both open vitrification [plastic straw (PS) and plastic vials (PV)] and closed ultravitrification [microdrop (MD) and solid surface vitrification (SSV)], after protocol optimization. However, open ultravitrification resulted in better post-warming viability than closed systems of vitrification with highest success obtained in modified SSV (84.8 ± 1.86%; p < 0.05). Leydig cells vitrified-warmed by modified SSV also showed superior (p < 0.05) cell growth, mitochondrial activity and cytoplasmic esterase enzyme activity, than MD, PS and PV, respectively. It was also observed that vitrified-warmed cells had higher level of ROS activity than non-vitrified control cells (41.6 ± 4.0 vs. 16.7 ± 1.0; p < 0.05). Treatment of cells with glutathione (GSH) or 2-mercaptoethanol (2-ME) (0, 10, 50, 100 μM) significantly (p < 0.05) reduced the ROS activity but had no significant (p > 0.05) effect on post-warm viability. Nevertheless, antioxidant-treated cells had improved mitochondrial activity, cytoplasmic esterase activity and cell growth during in vitro culture (p < 0.05). In conclusion, our results suggest that modified SSV offers a viable method for vitrifying single cell suspension of Leydig cells. To the best of our knowledge, this is the first report on cryopreservation of Leydig cells by vitrification.

Abstract
Cryopreservation is an essential tool to meet the increasing demand for stem cells in medical applications. To ensure maintenance of cell function upon thawing, the preservation of the actin cytoskeleton is crucial, but so far there is little quantitative data on the influence of cryopreservation on cytoskeletal structures. For this reason, our study aims to quantitatively describe cryopreservation induced alterations to F-actin in adherent human mesenchymal stem cells, as a basic model for biomedical applications. Here we have characterised the actin cytoskeleton on single-cell level by calculating the circular standard deviation of filament orientation, F-actin content, and average filament length. Cryo-induced alterations of these parameters in identical cells pre and post cryopreservation provide the basis of our investigation. Differences between the impact of slow-freezing and vitrification are qualitatively analyzed and highlighted. Our analysis is supported by live cryo imaging of the actin cytoskeleton via two photon microscopy. We found similar actin alterations in slow-frozen and vitrified cells including buckling of actin filaments, reduction of F-actin content and filament shortening. These alterations indicate limited functionality of the respective cells. However, there are substantial differences in the frequency and time dependence of F-actin disruptions among the applied cryopreservation strategies; immediately after thawing, cytoskeletal structures show least disruption after slow freezing at a rate of 1°C/min. As post-thaw recovery progresses, the ratio of cells with actin disruptions increases, particularly in slow frozen cells. After 120 min of recovery the proportion of cells with an intact actin cytoskeleton is higher in vitrified than in slow frozen cells. Freezing at 10°C/min is associated with a high ratio of impaired cells throughout the post-thawing culture.

Abstract
Human induced pluripotent stem cells (hiPSCs) are an important tool for research and regenerative medicine, but their efficient cryopreservation remains a major challenge. The current gold standard is slow‐rate freezing of dissociated colonies in suspension, but low recovery rates limit immediate post‐thawing applicability. We tested whether ultrafast cooling by adherent vitrification improves post‐thawing survival in a selection of hiPSCs and small molecule neural precursor cells (smNPCs) from Parkinson's disease and controls. In a dual‐center study, we compared the results by immunocytochemistry (ICC), fluorescence‐activated cell sorting analysis, and RNA‐sequencing (RNA‐seq). Adherent vitrification was achieved in the so‐called TWIST substrate, a device combining cultivation, vitrification, storage, and post‐thawing cultivation. Adherent vitrification resulted in preserved confluency and significantly higher cell numbers, and viability at day 1 after thawing, while results were not significantly different at day 4 after thawing. RNA‐seq and ICC of hiPSCs revealed no change in gene expression and pluripotency markers, indicating that physical damage of slow‐rate freezing disrupts cellular membranes. Scanning electron microscopy showed preserved colony integrity by adherent vitrification. Experiments using smNPCs demonstrated that adherent vitrification is also applicable to neural derivatives of hiPSCs. Our data suggest that, compared to the state‐of‐the‐art slow‐rate freezing in suspension, adherent vitrification is an improved cryopreservation technique for hiPSCs and derivatives. stem cells translational medicine2019;8:247&259

Abstract
Safe and stable cryopreservation is critical for research involving human embryonic stem cells (hESCs). Dimethyl sulfoxide (DMSO) is a popular cryoprotective agent; however, its cytotoxicity cannot be ignored. Thus, there is a need for an alternate cryoprotectant. We reported previously that a novel cryopreservation reagent, StemCell Keep™ (SCK), was effective for cryopreserving human induced pluripotent stem cells (hiPSCs) by vitrification. Because hESCs and hiPSCs are not identical, the current study examined the use of SCK on hESCs. hESCs cryopreserved with SCK were thawed and cultured on SNL 76/7 cells, which were derived from a mouse fibroblast STO cell line transformed with neomycin resistance and murine LIF genes. After cryopreservation, cultured hESCs were assessed for their attachment ability and characterized by alkaline phosphatase (AP) and immunocytochemical (ICC) staining, fluorescence-activated cell sorting (FACS), reverse transcription polymerase chain reaction (RT-PCR), and karyotyping. The proliferation of SCK-cryopreserved hESCs cultured on SNL cells, or in feeder-free conditions, was higher than that of cells preserved in a solution of 2 M DMSO, 1 M acetamide, and 3 M propylene glycol (DAP). The cell number with SCK-cryopreserved hESCs was about twice that of hESCs cryopreserved in DAP. The pluripotency of SCK-cryopreserved hESCs was similar to that of DAP-cryopreserved hESCs based on AP staining. Data from ICC, FACS, and RT-PCR analyses showed that stem cell markers were continually expressed on SCK-cryopreserved hESCs. The teratoma assay showed that SCK-cryopreserved hESCs differentiated into three germ layers. Furthermore, SCK-cryopreserved hESCs had normal karyotypes. These data indicate that SCK was effective for cryopreservation of hESCs by vitrification.

Abstract
Due to their high biological complexity, e.g., their close cell-to-cell contacts, cryopreservation of human pluripotent stem cells with standard slow-rate protocols often is inefficient and can hardly be standardized. Vitrification that means ultrafast freezing already showed very good viability and recovery rates for this sensitive cell system, but is only applicable for low cell numbers, bears a high risk of contamination, and can hardly be implemented under GxP regulations. In this chapter, a sterile plate-based vitrification method for adherent pluripotent stem cells and their derivatives is presented based on a procedure and device for human embryonic stem cells developed by Beier et al. (Cryobiology 66:8-16, 2013). This protocol overcomes the limitations of conventional vitrification procedures resulting in the highly efficient preservation of ready-to-use adherent pluripotent stem cells with the possibility of vitrifying cells in multi-well formats for direct application in high-throughput screenings.

Abstract
Efficient cryopreservation of human stem cells is crucial for guaranteeing a permanent supply of high-quality cell material for drug discovery or regenerative medicine. Conventionally used protocols usually employing slow freezing rates, however, result in low recovery rates for human pluripotent stem cells due to their complex colony structure. In this chapter, a surface-based vitrification protocol for pluripotent stem cells is presented based on a procedure for human embryonic stem cells developed by Beier et al. (Cryobiology 63:175-185, 2011). This simple and highly efficient cryopreservation method allows cryopreservation of large numbers of ready-to-use adherent cells that maintain pluripotency.

Abstract
This unit describes a cryopreservation procedure using an enzyme-free dissociation method to harvest cells and preserve cells in albumin-free chemically defined E8 medium for human pluripotent stem cells (hPSCs). The dissociation by EDTA/PBS produces small cell aggregates that allow high survival efficiency in passaging and cryopreservation. Cryopreservation in E8 medium eliminates serum and other animal products, and is suitable for dealing with the increasing demand for high-quality hPSCs in translational research. In combination with the special feature of EDTA/PBS dissociation, the protocols in this unit allow for efficient cryopreservation in a more time-saving manner.
