Project description:Background: Bone marrow stromal cells (BMSCs) have classically been cultured in media supplemented with 20% fetal bovine serum (FBS). As an alternative to FBS, pooled solvent detergent apheresis platelets, HPGF-C18, was evaluated for BMSC culture. Methods: A comparison of passage 2 BMSC growth revealed that 10% HPGF-C18 produced similar cell numbers as 20% FBS. Marrow aspirates from 5 healthy subjects were cultured for 4 passages in 10% HPGF-C18 or 20% FBS and were analyzed for proliferation, colony formation efficiency (CFE), surface marker expression, suppression of mixed lymphocyte reactions (MLRs), global gene and microRNA expression analysis. BMSC supernatant cytokine and growth factor concentrations were also compared. Results: Primary cultures of marrow aspirates in 10% HPGF-C18 and 20% FBS yielded similar numbers and CFE. After 4 passages, 10% HPGF-C18 and 20% FBS yielded similar numbers of BMSCs, surface marker expression patterns and immunosuppression effects. Gene and microRNA expression analysis revealed that BMSCs cultured under the two conditions had distinct expression profiles. Gene Set Enrichment Analysis (GSEA) revealed HPGF-C18-cultured BMSCs were enriched in metabolic processing and biosynthetic pathways; cell proliferation and cell cycle pathways; and immune response pathways. FBS-cultured BMSCs were enriched in MAPK signaling, TGF-beta signaling, cell adhesion and extracellular matrix pathways. Differently expressed microRNAs were related to the osteogenesis of BMSCs. Supernatant analysis found that HPGF-C18 BMSCs displayed higher levels of PEDF and TGFB1 and lower levels of IL6, VEGF, SDF1 and PLGF. Conclusions: Traditional measures; expansion, surface marker expression and inhibition of MLRs suggest that BMSC cultured in HPGF-C18 and FBS were similar, but analysis at the molecular level revealed many differences. BMSCs cultured in HPGF-C18 should be assessed in specific functional assays that reflect application-specific potency before substituting FBS with HPGF-C18.

Project description:Culture medium of mesenchymal stromal cells (MSCs) is usually supplemented with either human platelet lysate (HPL) or fetal calf serum (FCS). Many studies have demonstrated that proliferation and cellular morphology is influenced by these additives – hence they may favor outgrowth of specific subpopulations, thereby affecting the heterogeneous composition of MSCs. We have isolated and expanded human bone marrow derived MSCs in parallel with HPL or FCS for two passages. In HPL the proliferation was significantly higher and cells reflected more spindle-shaped morphology. Pairwise comparisons of gene expression profiles (Affymetrix HTA 2.0) revealed only moderate differences. When we apply a fold change >1.5 and limma-adjusted P-value of <0.05, only 69 transcripts were differentially expressed. These results indicate that there is no systematic bias for specific subpopulations of MSCs by using either HPL or FCS.

In HPL the proliferation was significantly higher and cells reflected more spindle-shaped morphology. In contrast, global DNA-methylation profiles did not reveal any significant differences. None of the CpGs revealed significant differences between MSCs that were cultured in HPL versus FCS if the analysis was corrected for multiple testing (limma-adjusted P-value of <0.05). These results indicate that there is no systematic bias for specific subpopulations of MSCs by using either HPL or FCS.

Project description:Mesenchymal stromal cells (MSCs) are promising candidates for innovative cell therapeutic applications. For clinical scale manufacturing regulatory agencies recommend to replace fetal bovine serum (FBS) commonly used in MSC expansion media as soon as equivalent alternative supplements are available. We already demonstrated that pooled blood group AB human serum (HS) and thrombin-activated platelet releasate plasma (tPRP) support the expansion of multipotent adipose tissue-derived MSCs (ASCs). Slight differences in size, growth pattern and adhesion prompted us to investigate the level of equivalence by compiling the transcriptional profiles of ASCs cultivated in these supplements. A whole genome gene expression analysis was performed and data verified by PCR and protein analyses. Microarray-based screening of 34,039 genes revealed 102 genes differentially expressed in ASCs cultured with FBS compared to HS or tPRP supplements. A significantly higher expression in FBS cultures was found for 90 genes (fold change .2). Only 12 of the 102 genes showed a lower expression in FBS compared to HS or tPRP cultures (fold change .0.5). Differences between cells cultivated in HS and tPRP were hardly evident. Supporting previous observations of reduced adhesion of cells cultivated in the human alternatives we detected a number of adhesion and extracellular matrix associated molecules expressed at lower levels in ASCs cultivated with human supplements. Confirmative assays analysing transcript or protein expression with selected genes supported these results. Likewise a number of mesodermal differentiation associated genes were higher expressed in cells grown in FBS. Quantifying adipogenic and osteogenic differentiation lacked to demonstrate a clear correlation to the supplement due to donor-sepcific variances. Our results emphasize the necessity of comparability studies as they indicate that FBS induces a culture adaptation exceeding that of ex vivo culture in human supplements and thus may contribute to the therapeutic potential.

Microarray hybridizations (Agilent: Whole Human Genome Oligo Microarray; 41k unique probe) were carried out with 5 µg Cy3 labeled cRNA and 5 µg Cy5 labeled cRNA, both prepared from each sample.

Project description:Human adipose stem cells (ASCs) have been shown, in pre-clinical studies, to have therapeutic applicability in diverse fields, but a standard expansion method for clinical applications remains yet to be established. Isolated ASCs are typically expanded in medium containing fetal bovine serum (FBS). However, sera and other animal-derived culture reagents stage numerous safety issues in clinical therapy, including possible infections and severe immune reactions. By expanding the ASCs in medium containing human serum (HS), the problem can be eliminated. To define how allogeneic HS performs in ASC expansion compared to FBS, we used microarrays to explore differences in gene expression between human adipose stem cells expanded in allogeneic human serum and fetal bovine serum.

To define how allogeneic HS performs in ASC expansion compared to FBS, we used microarrays to explore differences in gene expression between human adipose stem cells expanded in allogeneic human serum and fetal bovine serum. Adipose stem cells from 5 human donors were cultured in two media containing either 1) 10 % fetal bovine serum or 2) 15 % allogeneic human serum, and collected for RNA extraction and hybridization to 10 Affymetrix arrays. This experiment represents a paired design since cells of each donor were cultured in both conditions.

Project description:In preclinical studies, human adipose stem cells (ASCs) have been shown to have therapeutic applicability, but standard expansion methods for clinical applications remain yet to be established. ASCs are typically expanded in the medium containing fetal bovine serum (FBS). However, sera and other animal-derived culture reagents stage safety issues in clinical therapy, including possible infections and severe immune reactions. By expanding ASCs in the medium containing human serum (HS), the problem can be eliminated. To define how allogeneic HS (alloHS) performs in ASC expansion compared to FBS, a comparative in vitro study in both serum supplements was performed. The choice of serum had a significant effect on ASCs. First, to reach cell proliferation levels comparable with 10% FBS, at least 15% alloHS was required. Second, while genes of the cell cycle pathway were overexpressed in alloHS, genes of the bone morphogenetic protein receptor-mediated signaling on the transforming growth factor beta signaling pathway regulating, for example, osteoblast differentiation, were overexpressed in FBS. The result was further supported by differentiation analysis, where early osteogenic differentiation was significantly enhanced in FBS. The data presented here underscore the importance of thorough investigation of ASCs for utilization in cell therapies. This study is a step forward in the understanding of these potential cells.

Project description:Stem cells from human exfoliated deciduous teeth (SHED) can be used as a potential clinical material. But the use of xenogeneic ingredients, especially fetal bovine serum, will increase the risk of zoonotic disease transmission during the use of animal-derived products. Human-platelet-lysate (hPL) was used in human cell expansion with reliability in clinical applications. This study aimed to explore the feasibility and effect of HPL in the cultivation of SHED. We use proteomics to interpret the impact of HPL on the protein profile of SHED. Propagation, differentiation, qPCR and immunofluorescence were used to detect the effect of HPL on SHED.
