transcripts for either the k 14 keratin or the k 10 keratin were restricted in their spatial distribution within stratified epithelia consistent with the stage of differentiation of the keratinocyte : the k 14 keratin gene transcript was restricted to the basal cell layers of the mucosa , while the k 10 keratin transcript was expressed predominantly in suprabasal cells , within the granular and prickle layers .
