to investigate possible mechanisms through which 1,25-dihydroxyvitamin d3 ( 1,25- ( oh ) 2d3 ) affects cell proliferation and differentiation , we have studied the effects of 1,25- ( oh ) 2d3 on the binding and mitogenic activity of epidermal growth factor ( egf ) in rcj 1.20 cells , an established , non-tumorigenic cell line derived from 21-day-old fetal rat calvaria .
