a comparative analysis of the sequential changes in epidermal morphology and keratin pattern during the last third of embryonic development confirms the view that , independent of the species , keratin polypeptides below 60,000 mol . wt . are generated by basal cells , whereas the biosynthesis of high molecular weight keratin members take place in the suprabasal cell compartments of keratinizing epithelia .
