Control of Differentiation of Human Mesenchymal Stem Cells by Altering the Geometry of Nanofibers
Figure 4
Differentiation of MSC on nanofiber in the mixed medium for 7 days. (A) Phase contrast images of differentiated MSC. MSCs were stained by alkaline phosphatase ((a)โ(c)) and with Oil-Red-O. ((d)โ(f)) Cells were cultured on a flat dish, ((a) and (d)) aligned fibers, ((b) and (e)) and random fibers. ((c) and (f)) Bar = 500โฮผm. (B) Quantitative analysis of osteoinduction. (C) Quantitative analysis of adipoinduction. (*: ; ยง: ).
