The placenta, a transient organ in human, is essential for pregnancy maintenance and for fetal growth and development. Trophoblast and stromal cells are the main cell types present in human placenta. Trophoblast cells are present in different subtypes depending on their differentiation state and their temporal and spatial location during pregnancy. The stromal cells are of extraembryonic mesenc...
Marginal keratoderma of the palms (MKP), also known as degenerative collagenous plaques of the hands, is an infrequent disease affecting individuals with photoaged skin and submitted to mechanical trauma of the hands. The aim of the study was to study the expression of keratin 14 (K14) in the basal layer and keratins 10 (K10) and 16 (K16) in the suprabasal layer, and to establish the effect of ...
In epidermal cells, keratin intermediate filaments connect with desmosomes to form extensive cadherin-mediated cytoskeletal architectures. Desmoplakin (DPI), a desmosomal component lacking a transmembrane domain, has been implicated in this interaction, although most studies have been conducted with cells that contain few or no desmosomes, and efforts to demonstrate direct interactions between ...
Using mRNA from cultured human mesothelial cells, we constructed bacterial plasmids and lambda phage vectors that contained cDNA sequences specific for the keratins expressed in these cells. A cloned cDNA encoding keratin K7 (55 kD) was identified by positive hybrid selection. Southern Blot analysis indicated that this sequence is represented only once in the human genome, and Northern Blot ana...
AIM To examine the value of immunohistochemistry in defining a keratin profile to aid cervical histopathological diagnosis. METHODS Immunohistochemical localisation of keratins 17, 10, and 19 was studied in 268 cervical biopsies from 216 women including normal epithelia (with and without human papilloma virus), low and high grade cervical intraepithelial neoplasia, and invasive carcinoma. The...
Pancreatic acinar cells express keratins 8 and 18 (K8/18), which form cytoplasmic filament (CF) and apicolateral filament (ALF) pools. Hepatocyte K8/18 CF provide important protection from environmental stresses, but disruption of acinar cell CF has no significant impact. We asked whether acinar cell ALF are important in providing cytoprotective roles by studying keratin filaments in pancreata ...
