Fig. 3From: Cryopreservation in 95% serum with 5% DMSO maintains colony formation and chondrogenic abilities in human synovial mesenchymal stem cellsAnalysis of colony formation. a Representative dishes stained with crystal violet. Synovial mesenchymal stem cells (MSCs) were derived from four donors. b Colony numbers per dish. Data are shown as means ± SD (n = 4 for each donor). *p < .05 by the Friedman test followed by Dunn’s multiple comparisons. c Cell numbers per dish. d Cell numbers per colonyBack to article page
