Isolate, culture and identify the fetal BMSCs of goats. a Morphology of fetal BMSCs were obtained from the goats; b the growth curve of fetal BMSCs (passage 3) on day 1, 3, 5, 7, 9, 11; c CFU of the fetal BMSCs after 21 days (stained by crystal violet); d Alizarin red S after 10 days’ osteogenic induction of BMSCs (passage 3); e Oil red O after 3 weeks’ lipid induction of BMSCs (passage 3); f Toluidine blue after 3 weeks’ chondrogenic induction of BMSCs (passage 3). Scale bar: a 25 μm; (d–f) 80 μm
