Exposure to K2TS does not influence the multipotency of MSC. Unmanipulated cells (A,E,I,M), K2TS-treated, untransduced (B,F,J,N), AdV-transduced (C,G,K,O), and AdV-transduced in the presence of K2TS (D,H,L,P) were cultured in normal MSC medium (A–D) and (I–L), or in adipogenic medium (E–H) or in osteogenic medium (M–P) for two weeks. The cells treated as described above were stained with Oil Red O (A–H), or with von Kossa protocol (I–P). Bars are 50 µm (A–H) and 200 µm (I–P).
