- Comparisons in each indicated passage (P; P2, P6, P10) between WJ-MSCs (n = 18) and BM-MSCs (n = 18) have been performed by the nonparametric Mann–Whitney U test and the statistically significant P values are shown
-
Abbreviations: WJ-MSCs Wharton’s jelly-mesenchymal stem cells, BM-MSCs bone marrow-mesenchymal stem cells, SA-β-gal senescence-associated β galactosidase, N.S. no statistically significant difference
