Sebocytes

Sebocytes are the specialized epithelial cells that constitute the sebaceous glands, which are usually associated with hair follicles. They synthesize and secrete sebum, an oily, lipid-rich mixture of triglycerides, wax esters, and squalene. Sebum lubricates the skin and hair, provides a protective barrier, and has antimicrobial properties. Sebocytes undergo holocrine secretion, where the entire cell disintegrates to release its contents.
