Morphological and Molecular Analysis of In Vitro Tubular Structures from Bovine Yolk Sac-Derived MSCs

Figure 1

Photomicrographs of the tubular structure formed from bYS-MSCs. Fibroblast-like morphology that adhered to the plastic culture surface (arrow) (a); adherent cells began to organize into a network with a cobweb appearance (b–d); tubular structures (e, f). Scale bar: 50 μm.
