title: Polypeptide synthesis in columnar and squamous explants of human uterine cervix.
abstract: There were quantitative and qualitative differences in the in-vitro synthesis of 3 polypeptides between squamous and columnar epithelial explants of human cervix. One cross-linked keratin-like polypeptide of mol. wt 50,000 was synthesized and phosphorylated by squamous but not by columnar explants; a second cross-linked keratin-like polypeptide of mol. wt 52,000, which was present in larger amounts in squamous than columnar explants, was both glycosylated and phosphorylated during in-vitro explantation of squamous tissue; a third polypeptide of mol. wt 25,200 which was keratin-like but not cross-linked, was synthesized in squamous-tissue explants but in only 4% of columnar-tissue explants.
