Dithranol downregulates expression of Id1 mRNA in human keratinocytes in vitro

Dithranol downregulates expression of Id1 mRNA in human keratinocytes in vitro.

The precise causes of psoriasis, a chronic skin disorder characterized by hyperproliferation of keratinocytes and incomplete keratinization, are unclear. It is known that expression of helix-loop-helix transcription factor Id1, which functions as an inhibitor of differentiation, is upregulated in psoriatic skin. We investigated the effect of the antipsoriatic drug dithranol on mRNA and protein ...

Isolation and in vitro cultivation of human skin Keratinocytes and preparation of epidermal sheet

In vitro Co-Culture of Human Skin Keratinocytes and Fibroblasts on a Biocompatible and Biodegradable Scaffold

Background: Extensive full-thickness burns require replacement of both epidermis and dermis. In designing skin replacements, the goal has been to re-create this model and make a product which has both essential components. Methods: In the present study, we developed procedures for establishing confluent, stratified layers of cultured human keratinocytes on the surface of modified collagen-chito...

the effect of e-64 on the developmental competence of sheep cocs during in vitro maturation

in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.

HLA-G: expression in human keratinocytes in vitro and in human skin in vivo.

Classical, polymorphic major histocompatibility complex class I molecules are expressed on most nucleated cells. They present peptides at the cell surface and, thus, enable the immune system to scan peptides for their antigenicity. The function of the other, nonclassical class I molecules in man is controversial. HLA-G which has been shown by transfection experiments to be expressed at the cell...
