Fig. 2From: Heterogeneity of proangiogenic features in mesenchymal stem cells derived from bone marrow, adipose tissue, umbilical cord, and placentaMSCs derived from different tissue sources display distinct tube formation capacities on Matrigel in vitro. MSCs were seeded on Matrigel in vitro at 2 × 104 cells/well. MSCs could form tube-like structures on Matrigel temporarily (a). Representative photographs were taken after 12 hours of incubation (scale bar = 500 μm). b Numbers of tube structures were counted and analyzed (BMSC, n = 2; AMSC, UMSC, and PMSC, n = 3). Each sample was performed in triplicate (*p < 0.05, ****p < 0.0001).
