Cytokeratin 17 Lysates

Among the members of the cytokeratin (CK) subfamily of intermediate filament (IF) proteins, CK 17 is normally expressed in the basal cells of complex epithelia but not in stratified or simple epithelia. It has an unusual expression pattern in normal and diseased states and has potential importance in tumor diagnosis. CK 17 synthesis seems to be a marker of basal cell differentiation in complex epithelia and therefore indicative of a certain type of epithelial stem cells (1). It has been shown ...
