Figure Lengend Snippet: Colorimetric staining and quantification of ALP activity in hBM-MSCs cultured for seven days on collagen type I-coated (a) and fibronectin-coated (b) substrates. Results are expressed as mean ± SD (n=3). Data were analyzed assuming a Gaussian (normal) distribution and equal variances across groups; statistical differences were assessed using one-way ANOVA. Only p-values <0.1 are shown. Scale bar represents 200 µm.

Figure Lengend Snippet: hiPSC differentiate into cells with an MSC phenotype exhibiting common MSC markers. A schematic of the MSC differentiation protocol is shown (a) (Created with BioRender.com ). Fold gene expression increases in MSC marker-genes THY1 (CD90), NT5E (CD73) and ENG (CD105) was observed throughout differentiation of hiPSC-iMSCs (b). Histograms for common MSC positive markers are displayed (c) and increase of the percentage of cells positive for CD90, CD73 and CD105 after 36 days could also be noticed via flow cytometry (C-i to C-iii) after 36 days when iMSCs were derived. Homogenous iMSC populations comparable to hBM-MSCs positive for phenotypical MSCs markers CD44 and CD73 (green) as well as CD105 and CD90 (red) could be observed by day 34 of differentiation via Immunofluorescence staining (d). Scale bars shown at 100 μm. Data significance is presented as *** p ⩽ 0.001 and **** p ⩽ 0.0001 ( n = 3).
