Studies on the plasma membrane of normal and psoriatic keratinocytes.

Abstract
A method is described for the preparation of isolated [human] keratinocytes suitable for subsequent biochemical studies. Scanning electron microscopy showed that the maturation process is accompanied by an increase in cell size and a shortening and eventual loss of microvilli. Psoriatic keratinocytes are distinguishable by exhibiting longer microvilli at all levels of maturation.
