DMSO-free chemically defined cryopreservation of human mesenchymal stem cells and chondrocytes

ABSTRACT: Serum- and xeno-free cryopreservation is suitable for cells to be used in clinical applications. However, dimethyl sulfoxide (DMSO), which is often used in conventional cryoprotectant medium, has been shown to be toxic to many cell types and can induce morphological and gene expression changes that can lead to changes in cell function when they are cultured. In order to evaluate this issue in depth, we examined the efficiency of a DMSO-free/serum-free/xeno-free chemically defined cryoprotectant media, STEM-CELLBANKER DMSO-Free, when culturing human mesenchymal stem cells (MSCs) and chondrocytes. Interestingly, the cells cryopreserved in STEM-CELLBANKER DMSO-Free had a similar growth rate, morphology, and global gene expression profile compared to that observed for cells preserved in conventional freezing medium, which contains 10% DMSO and 20% fetal bovine serum. From these data, we therefore propose that STEM-CELLBANKER DMSO-Free may be an effective tool for maintaining the cellular characteristics of MSCs and chondrocytes during cryo-storage prior to clinical application.

Gene Expression Profile of Human Umbilical Cord Mesenchymal Stem Cells (hUC-MSCs) Culutured in Chemical Defined Serum Free Medium

Project description:Human umbilical cord mesenchymal stem cells maintained multipotency and immunosuppressive ability when being cultured in chemical defined serum free medium, but gained different gene expression profile. We used microarrays to identify the transcriptional difference between human umbilical cord mesenchymal stem cells cultured in serum containing medium and chemical defined serum free medium. human umbilical cord mesenchymal stem cells were cultured in conventional serum containing medium and chemical defined serum free medium separately. Total RNA was extracted and hybridized on Affymetrix microarrays.

Human serum-derived protein removes the need for coating in defined human pluripotent stem cell culture

Project description:Reliable, scalable and time-efficient culture methods are required to fully realize the clinical and industrial applications of human pluripotent stem (hPS) cells. Here we present a completely defined, xeno-free medium that supports long-term propagation of hPS cells on uncoated tissue-culture plastic. The medium consists of the Essential 8 (E8) formulation supplemented with Inter-α-inhibitor (IαI), a human serum-derived protein, recently demonstrated to activate key pluripotency pathways in mouse PS cells. IαI efficiently induces attachment and long-term growth of both embryonic and induced hPS cell lines when added as a soluble protein to the medium at seeding. IαI-supplementation efficiently supports adaptation of feeder-dependent hPS cells to xeno-free conditions, clonal growth as well as single-cell survival in the absence of Rho-associated kinase inhibitor (ROCKi). This time-efficient and simplified culture method paves the way for large-scale, high-throughput hPS cell culture, and will be valuable for both basic research and commercial applications.

Gene expression data of human dermal pilla cells, human induced pluripotent stem cell-derived CD271+CD90+ mesenchymal stem cells before and after the induction toward dermal papilla cells

Project description:To assess if human induced pluripotent stem cell-derived mesenchymal stem cells (hiPSC-MSCs) could be induce to acquire dermal papilla (DP) properties (especially hair inductive capacity), hiPSCs were initially programmed in serum-free MSC medium with FGF, TGFbeta and PDGF. Subsequently, hiMSCs were exposed to retinoic acid and activators of WNT, BMP and FGF signaling pathways. Global gene expression profiles were compared among primarily cultured human DP cells, hiPSC-MSCs before and after induction.

Mesenchymal stem/stromal cells from human pluripotent stem cell-derived brain organoid enhance the ex vivo expansion and maintenance of hematopoietic stem/progenitor cells

Project description:We report a novel method for harvesting MSCs from 3D human brain organoids under serum-free culture condition. The stromal cells, derived from both H1-hESCs and human induced pluripotent stem cells (hiPSCs) forebrain organoids, were capable of differentiating into the classical mesenchymal-derived cells (osteoblasts, chondrocytes, and adipocytes). These cells expressed MSC markers, thus named pluripotent stem cell-derived MSCs (pMSCs).To investigate the role of pMSCs, we compared the RNA sequencing of pMSCs ,umbilical cord-MSC,hiPSCs and H1 hESCs.To investigate the function pMSC in the regulation of umbilical cord blood HSPCs, we compared the RNA sequencing of CD34+ cells after co-culturing with and without pMSC and UC-MSCs,respectively.We then performed gene expression profiling analysis using data obtained from RNA-seq of 9 kinds of different cells.

Extracellular matrix-dependent generation of integration- and xeno-free iPS cells using a modified mRNA transfection method

Project description:In this study, we sought to examine whether an extracellular matrix (ECM)-based xeno-free culture system that we recently established could be used together with a microRNA-enhanced mRNA reprogramming method for the generation of clinically safe iPS cells. The notable features of this method are (1) the use of a xeno-free/feeder-free culture system for the generation and expansion of iPS cells rather than the conventional labor-intensive culture systems using human feeder cells or human feeder-conditioned medium and (2) the enhancement of mRNA-mediated reprogramming via the delivery of microRNAs. Strikingly, we observed the early appearance of iPS cell colonies (~11 days), substantial reprogramming efficiency (~0.2-0.3%), and a high percentage of ESC-like colonies among the total colonies (~87.5%), indicating enhanced kinetics and reprogramming efficiency. Therefore, the combined method established in this study provides a valuable platform for the generation and expansion of clinically safe (i.e., integration- and xeno-free) iPS cells, facilitating immune-matched cell therapy in the near future.

Xeno-free cultured Mesenchymal Stromal Cells release Extracellular Vesicles with a “therapeutic” miRNA cargo ameliorating cartilage inflammation in vitro

Project description:Mesenchymal Stromal Cells (MSCs)-derived Extracellular Vesicles (EVs) emerged as an innovative strategy for the treatment of osteoarthritis (OA). Biological activity of EVs is generally driven by their cargo, which might be influenced by microenvironment. Therefore, pre-conditioning strategies, including modifications in culture conditions or oxygen tension could directly impact on MSCs paracrine activity. Methods: A xeno-free supplement (XFS) was used for isolation and expansion of MSCs and compared to conventional fetal bovine serum (FBS) culture. Bone Marrow-derived MSCs (BMSCs) were pre-conditioned under normoxia (20% O2) or under hypoxia (1% O2) and EVs production was evaluated. Anti-OA activity was evaluated by using an in vitro inflammatory model. miRNA content was also explored, to select putative miRNA that could be involved in a biological function. Results: Modulation of IL-6, IL-8 and COX-2 was evaluated on hACs simultaneously treated with IL-1α and BMSC-derived EVs. FBS-sEVs exerted a blunt inhibitory effect, while a strong anti-inflammatory outcome was achieved by XFS-sEVs. Interestingly, in both cases hypoxia pre-conditioning allowed to increase EVs effectiveness. Analysis of miRNA content showed the upregulation in XFS-hBMSC-derived EVs of miRNA known to have a chondroprotective role, such as let-7b-5p, miR-17, miR-145, miR-21-5p, miR-214-3p, miR-30b-5p, miR-30c-5p. Activated pathways and target genes were investigated in silico and most of the upregulated miRNAs were found to be involved in TGF-beta and Wnt signalling pathways, by targeting genes related to cartilage homeostasis. Conclusions: XFS medium was found to be suitable for isolation and expansion of MSCs, secreting EVs with a therapeutic cargo. The application of cells cultured exclusively in XFS overcomes issues of safety associated with serum-containing media and makes ready-to-use clinical therapies more accessible.

Engineering bone-forming callus-organoid implants in a xenogeneic free differentiation medium

Project description:The field of tissue engineering aspires to provide clinically relevant solutions for patients through the integration of developmental engineering principles with a bottom up manufacturing approach. However, manufacturing of cell based advanced therapy medicinal products is hampered by protocol complexity, lack of non-invasive critical quality controls, and dependency on animal-derived components for tissue differentiation. We investigate a serum-free, chemically defined, xeno- and lipid-free chondrogenic differentiation medium to generate bone-forming callus organoids. Our results show an increase in microtissue homogeneity during prolonged differentiation and a high quality of in vivo bone forming organoids. The low protein content of the culture media potentially allows for monitoring of relevant secreted biomarkers as (critical) quality attributes . Together, we envisage that this xeno- and lipid-free chondrogenic medium is compatible with industrial scale-up and automation, while facilitating the implementation of non-invasive imaging and use of quality control parameters based on secreted biomarkers.

Transcription profiling of Mesenchymal stem cells (MSC) maintained in FCS vs autologous serum analysed at passage 4

Project description:The purpose of this study was to determine whether the serum condition affected the gene expression in mesenchymal stem cells (MSCs). To that end, we compared gene expression in MSCs maintained in regular growth medium supplemented with fetal calf serum (FCS) with gene expression of MSCs cultured in regular growth medium supplemented with autologous serum (AS) for 3 different donors (i.e. donor2, donor3 and donor4). MSCs were cultured in FCS- or AS-supplemented medium and were analyzed at passage 4.
