Fig 1. Proliferation of neonatal and adult cultured human airway smooth muscle cells in the presence of FCS and PDGF-AA.

Fig 1

A. Cell counts according to time. Results are means ± SEM. In glucose + 10% FCS medium, ASMC proliferation was greater in neonatal cells (open symbols, n = 5) vs. adult cells (closed symbols, n = 5). *p < 0.05 neonate vs. adult at the corresponding time using MANOVA. B. DNA synthesis in adult and neonatal cultured human airway smooth muscle cells. Results are means ± SEM. Values were normalized to proliferation in ITS medium. Cells cultured in 10% FCS (white bars, neonates, n = 5; black bars, adults, n = 7)), 15 ng/ml PDGF-AA (neonate, n = 4; adults, n = 10). *p < 0.05 using Mann-Whitney U-test.
