Modulating Mesenchymal Stem Cell Behavior Using Human Hair Keratin-Coated Surfaces

Figure 5

Colony-forming efficiencies of (a) Donor A and (b) Donor B hMSCs after being expanded on either uncoated or keratin-coated TCPS for 1 passage (P4 to P5, assessed at P5) and 3 passages (P4 to P7, assessed at P7). Corresponding micrographs above the bar charts depict representative hMSC colonies stained with crystal violet; , .
