Differences in hepatocyte growth factor (HGF) secretion dependent on cell population and colony number. (A) HGF concentrations do not significantly increase between week 1 and week 5 for cultures containing less than 0.5 × 106 viable cells after 5 weeks of culturing. (B) Increase in HGF levels is more pronounced in cultures with detectable colonies (right). Note the large overlap between the patients with higher cell numbers and colony formation.
