[Retracted] Effects of Coculture Fibroblasts and Vascular Endothelial Cells on Proliferation and Osteogenesis of Adipose Stem Cells

Figure 7

Alizarin red staining of adipose stem cells at each time point of coculture (scale: 50 μm). (a–d) In the figure are the ADSC group, ADSC+VEC group, ADSC+FB group, and ADSC+VEC+FB group, respectively. On day 28, there were red positive cells in all groups, and the ADSC+VEC+FB group was the most and ADSC group was the least. ADSCs: adipose stem cells; VECs: vascular endothelial cells; FB: fibroblasts.
