Web20 nov. 2024 · Summary. The epidermis is composed of layers of skin cells called keratinocytes. Your skin has four layers of skin cells in the epidermis and an additional fifth layer in areas of thick skin. The four layers of cells, beginning at the bottom, are the stratum basale, stratum spinosum, stratum granulosum, and stratum corneum. WebFor example, deletion of β1-integrin from the basal layer of the mammary epithelium causes spindle orientation defects, with mixing of the basal and luminal layers. 64 Furthermore, deletion of β1-integrin from the mammary gland was recently shown to block apical–basal polarity, by deregulating trafficking of apical proteins. 65 Therefore, a potential …
