Located at the skin surface, keratinocytes (KCs) are constantly exposed to external stimuli
and are the first responders to invading pathogens and injury. Upon skin injury, activated …

A large proportion of the cytoplasm of vertebrate cells, normal or transformed, is represented
by components of the cytoskeleton, including actin-containing microfilaments, tubulin …

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 …

Highly purified functional cytotrophoblasts have been prepared from human term placentae
by adding a Percoll gradient centrifugation step to a standard trypsin-DNase dispersion …

Keratin expression in human tissues and neoplasms Keratin filaments constitute type I and
type II intermediate filaments (IFs), with at least 20 subtypes named keratin 1–20. Since …

We have analyzed the proliferative and differentiation potential of human ocular
keratinocytes. Holoclones, meroclones, and paraclones, previously identified in skin …

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 …

Synaptophysin is an integral membrane glycoprotein (Mr 38,000) that occurs in presynaptic
vesicles of neurons and in similar vesicles of the adrenal medulla. By using a monoclonal …

Mechanically induced signal transduction has an essential role in development. Cells
actively transduce and respond to mechanical signals and their internal architecture must …
