The Comparison of Adipose Stem Cell and Placental Stem Cell in Secretion Characteristics and in Facial Antiaging

Figure 2

Multipotent differentiation of adipose stem cells and placenta stem cells. After 20 days of induction, the cells were stained with Alizarin Red, Oil Red, and Safranin O. Both kinds of cells could differentiate into osteocytes (a2, d2), adipocytes (b2, e2), and chondrocytes (c2, f2) successfully. And the uninduced groups were cells without induction as negative control (a1–f1). Scale bar = 50 μm.
