Chondrocyte Differentiation of Human Endometrial Gland-Derived MSCs in Layered Cell Sheets

Figure 4

Detection of sulfated glycosaminoglycan (sGAG) accumulation within layered cell sheets at 24 h after the start of cultivation. With increasing the number of stratified cell sheets (from single to sextuple), sGAG accumulation increased. Data are shown as the mean ± SD ( ). The sGAG accumulations within a cell sheet enhanced during 24-h cultivation after detachment ( ).
