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

Figure 1

Characterization of adipose stem cells and placenta stem cells. Both cells showed typical fibroblast-like morphology at passage 1 (a1, c1) and passage 3 (a2, c2). The flow cytometry analysis confirmed that adipose stem cells express CD29 (99.88%, b1) and CD90 (52.9%, b4) but do not express CD34 (0.99%, b2) and CD71 (1.17%, b3); the placenta stem cells express CD29 (99.9%, d1) and CD90 (80.45%, d4) but do not express CD34 (1.29%, d2) and CD71 (1.21%, d3). The FITC (b6, d6) and PE (b5, d5) were performed as blank control. UL refers to upper left quadrant and UR refers to upper right quadrant. Scale bar = 100 μm.
