角化是角朊细胞的一个重要特征。从基层细胞开始,角朊细胞不断分化,向上移行,经历棘层、颗粒层,最终成为角层细胞而完成其角化过程。

The proliferation of keratinocytes is usually accompanied by abnormal keratosis which appears parakeratosis and absent of granular layer in histological section and appears abnormalities of cytokeratin expression in biochemistry aspect.
角质形成细胞过度增生常常伴有异常角化过程,组织学表现为角化不全及颗粒细胞层消失,而生物化学则表现为细胞角蛋白的表达异常。

湿角化蛋白不同于表皮囊肿和皮样囊肿的成熟角化鳞状上皮。
"Wet" keratin is different from the mature (orthokeratotic) keratinous squames seen in epidermoid or dermoid cysts.
So again, if we think about that shape of that carbon atom, it's going to be trigonal planar, 120° it's going to have bond angles of 120 degrees, because we have this set up of having three hybrid orbitals.
如果我们考虑碳原子的形状,它是平面三角形,键角是,因为我们有这三个杂化轨道。
