Fig. 2. Characteristics of CD90^highand CD90^low gbMSCs cultured in vitro.

a, b Adherent growth patterns of CD90^high and CD90^low gbMSCs cultured in 10% DMEM (×40, scale bars = 200 µm). c FACS analysis of sorted CD90^high gbMSCs (n ≥ 3). d FACS analysis of sorted CD90^high gbMSCs (n ≥ 3). e Growth of CD90^high and CD90^low gbMSCs cultured in 10% DMEM (n ≥ 3). *P < 0.05, **P < 0.01. f Wound-healing assay of CD90^high and CD90^low gbMSCs (n ≥ 3) for 8 h with different media (×40, scale bars = 200 µm). *P < 0.05, **P < 0.01, ***P < 0.001 and ****P < 0.0001
