Comparative Analysis of Human Mesenchymal Stem Cells from Umbilical Cord, Dental Pulp, and Menstrual Blood as Sources for Cell Therapy

Figure 5

Senescence of UC-, DP-, and MB-MSCs. Senescence was assayed by SA-β-gal activity with positive green staining (100x, arrow). UC-MSCs: umbilical cord mesenchymal stem cells; DP-MSCs: dental pulp mesenchymal stem cells; MB-MSCs: menstrual blood mesenchymal stem cells; P: passage.
