Reacts with cytokeratin polypeptide 19. The antibody labels the basal layer of non-keratinizing epithelium, metaplastic epithelium of the cervix, simple epithelium, transitional epithelium, squamous cell carcinomas and adenocarcinomas expressing cytokeratin 19.
Immunogen
cytoskeletal proteins from the cultured human breast carcinoma cell line MCF-7
Application
Monoclonal Anti-Cytokeratin 4.62 antibody produced in mouse is suitable for indirect immunofluorescence at a dilution of 1:20 using frozen human tissue sections.
Biochem/physiol Actions
Cytokeratins are proteins of keratin-containing intermediate filaments that provide mechanical support and other additional functions in epithelial cells. It is found in the intracytoplasmic cytoskeleton of epithelial tissue. Epithelial tissue expresses cytokeratin subunits in a specific and stable pattern. Cytokeratins along with vimentin are involved in cell proliferation, migration and differentiation of preodontoblasts and preameloblasts. The intermediate-sized filaments are abundant in human endothelial cells and are mostly of vimentin type.

Hepatic progenitor cells (HPCs) are bipotential stem cells residing in human and animal livers that are able to differentiate towards the hepatocytic or cholangiocytic lineages. HPCs are present in both hepatocellular (HCC) and cholangiocellular carcinoma (CC) in humans; and a

Transforming growth factor-alpha (TGF-alpha) and hepatocyte growth factor (HGF) are strong hepatocyte mitogens and important regulators of liver regeneration. The TGF-alpha receptor EGFr appears primarily to mediate a proliferative signal, whereas mitogenic, motogenic, and morphogenic effects have been attributed to

When hepatocyte replication during liver disease is insufficient for regeneration, liver progenitor cells (LPCs) are activated. The cells and stroma in the immediate environment of LPCs, together termed the LPC niche, are thought to play an important role in this
Fifteen adult Soay rams were employed in this study to investigate the effect of melatonin on the scrotal skin using histological, histochemical, and morphometrical analysis. The results revealed that the melatonin treated group showed a significant increase in the thickness
