Table 2.
Cell density (cells/mm2) of hDPSC microtissues cultured with proliferation or chondrogenic differentiation media for 3 days and 2, 4, and 6 weeks. Samples at initial time (t = 0; cell density: 9,400 ± 600) were taken as control. Values shown (mean ± SD) are ×103. Statistical significance at p ≤ 0.05 with respect to control (∗) and to samples cultured with proliferation medium for the same period of time (#).
