further characterization of the bioactivity of the growth factor reveals that it exerts mitogenic effects also on vascular endothelial cells isolated from several districts but not on adrenal cortex cells , lens epithelial cells , corneal endothelial cells , keratynocytes or bhk-21 fibroblasts , indicating that its target cells specificity is unlike that of any previously characterized growth factor .
