A ubiquitous biological material, keratin represents a group of insoluble, usually high-sulfur
content and filament-forming proteins, constituting the bulk of epidermal appendages such …

The keratins are the typical intermediate filament proteins of epithelia, showing an
outstanding degree of molecular diversity. Heteropolymeric filaments are formed by pairing …

In this paper we present keratin expression data that lend strong support to a model of
corneal epithelial maturation in which the stem cells are located in the limbus, the …

The delivery of drugs via the mucous membranes lining the oral cavity (ie, sublingual and
buccal), with consideration of both systemic delivery and local therapy, is reviewed in this …

The authors have recently identified a new cytokeratin (CK) polypeptide, CK 20, whose
expression is almost entirely confined to the gastric and intestinal epithelium, urothelium …

The epithelial-specific cell-cell adhesion molecule E-cadherin was analyzed
immunohistochemically on tissue sections of 89 human primary infiltrating breast …

We have identified, cultured, characterized, and propagated adult pluripotent stem cells
(PSC) from a subset of human peripheral blood monocytes. These cells, which in …

Corneal epithelium is traditionally thought to be a self-sufficient, self-renewing tissue
implying that its stem cells are located in its basal cell layer. Recent studies indicate …

Septins are an evolutionarily conserved group of GTP‐binding and filament‐forming
proteins that belong to the large superclass of P‐loop GTPases. While originally discovered …

A major cytoskeletal polypeptide (Mr• 46,000; protein IT) of human intestinal epithelium was
characterized by biochemical and immunological methods. The polypeptide, which was …
