WebWhat is the Cornified cell envelope? The cornified cell envelope is a highly insoluble and extremely tough structure formed beneath the cell membrane during terminal differentiation of keratinocytes. Its main function is to provide human skin with a protective barrier against the environment. WebJan 18, 2024 · The cornified envelope contains several structural proteins such as involucrin, loricrin, and trichohyalin; small proline-rich proteins; and natural moisturizing factors (NMFs) and water, while lipid lamellae are composed of ceramides, cholesterol, and free fatty acids, which constitute hydrophilic and hydrophobic skin barriers. Corneocytes WebEpidermal keratinocytes undergo a unique form of terminal differentiation and programmed cell death known as cornification. Cornification leads to the formation of the outermost skin barrier, i.e. the cornified layer, as well as to the formation of hair and nails. Different genes are expressed in co … daughters of ww2
