Proliferation capacity is enhanced for different stromal cells in pHPL-based media compared to FBS-supplemented medium. Proliferative capacity of stromal cells expanded in either pHPL- (red), pHPLS- (orange) or mcpHPL- (green) compared to FBS- (blue) medium of UC- and WAT-derived stromal cells. Data are shown as cumulative population doublings (cPD) of three independent stromal cell donations for each tissue source tested in duplicates ± SD (⁺p < 0.05 comparing pHPL/pHPLS to FBS-supplementation; *p < 0.05, **p < 0.01, ***p < 0.001, all pHPL-media compared to FBS-supplementation)
