Figure 3

(a) Images of detached type I collagen gel contraction by nonsenescent (30 PDs), high proliferative/multipotent DPSC subpopulation, A3, over 12 days in culture. (b) Mean % detached type I collagen gel contraction by high proliferative/multipotent DPSC subpopulation, A3, at early (nonsenescent, 30 PDs) and late (approaching senescence, 80 PDs) stages in their proliferative lifespans, and low proliferative/unipotent DPSCs, A1 (approaching senescence, 17 PDs), over 12 days in culture. N = 3, mean ± SEM, ∗∗∗p < 0.001, ∗∗p < 0.01.
