Chondrogenic Potency Analyses of Donor-Matched Chondrocytes and Mesenchymal Stem Cells Derived from Bone Marrow, Infrapatellar Fat Pad, and Subcutaneous Fat

Figure 2

Immunoprofiles for MSC markers and putative chondrogenic potency markers of culture expanded cells prior to chondrogenesis. (a) ISCT MSC immunoprofiles. Immunoprofiles for the putative chondrogenic markers CD49c (b), CD166 (c), and CD39 (d). Flow cytometry was used to detect the percentage of positive cells for each marker on monolayer cell populations of chondrocytes (Ch), bone marrow MSC (BM), fat pad MSC (FP), and subcutaneous fat MSC (SCF) prior to chondrogenesis. Data shown are the means the standard deviation of 5 donors for each cell population. One-way ANOVA and post hoc Bonferroni tests were used to test for significant differences in the positivity of cell surface markers between cell types.
