to determine whether epidermal growth factor ( egf ) or egf-like transforming growth factors ( tgfs ) are present in ovine fetal tissues , we have tested acid-ethanol extracts of ovine fetal kidney for the ability to induce anchorage-independent growth of normal rat kidney fibroblasts in soft agar and to compete with 125i-mouse egf for binding to receptors in sheep liver .
