Comparison of cell capacitance between (A) all chondrocytes
subgroups, (B) all chondroprogenitor subgroups,
(C) all subgroups at passage 0, and (D)
all subgroups at passage 5. Data expressed as mean ± SEM
(*P < 0.05, **P < 0.01,
using Wilcoxon rank-sum test for A and B; Wilcoxon signed rank test for
C and D). N = normal; OA = osteoarthritic; C = chondrocytes; CP =
chondroprogenitors; p0 = passage 0; p5 = passage 5.
