Cell culture in vitro. BMSCs (a) and CPCs (b) were found to form colonies after 2 weeks of primary culture, while chondrocytes were uniformly distributed (c). BMSCs (d) and CPCs (e) at passage 1 were arranged in whorls or bundles, while chondrocytes (f) were polygonal. (g) There was a significant difference in proliferation among these three cell populations (*p < 0.05)
