Figure 2From: Human adipose-derived stem cells cultured in keratinocyte serum free medium: Donor’s age does not affect the proliferation and differentiation capacitiesGrowth kinetics of ASC derived from the three age groups. Growth kinetics, as indicated as mean ± SD of the OD read of cell density, of the three age groups are showed. The case number of the 30-39 y, 40-49 y and over 50 y groups was 10, 10 and 7, respectively. * P < 0.05.Back to article page
