Proliferation of PAH and non PAH HPASMC in quiescence medium.

<p>Cells were cultured in quiescence medium containing 0.2% FBS. Cell number of each strain was determined in triplicate after 5 days in quiescence medium. Bar graphs represent the average cell number and the error bars are the standard deviation. *p < 0.005 vs non PAH. Results are representative of a number of experiments with various strains of non PAH, hPAH and iPAH cells.
