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

Figure 8

Alkaline phosphatase 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, except the adipose stem cell group, cells in other groups had obvious red positive particles. The adipose stem cell+fibroblast coculture group and adipose stem cell+vascular endothelial cell+fibroblast coculture group had the most, and adipose stem cell+vascular endothelial cell coculture group had less. ADSCs: adipose stem cells; VECs: vascular endothelial cells; FB: fibroblasts.
