The keratinocyte growth factor (KGF), also known as FGF7, is a growth factor present in the epithelialization-phase of wound healing. In this phase, keratinocytes are covering the wound, forming the epithelium. KGF is a small signaling molecule that binds to fibroblast growth factor receptor 2b (FGFR2b). [1]
The anagen phase, known as the growth phase, is when the hair grows about 1 cm per month. [11] It begins in the papilla and can last from three to five years. [12] The span at which the hair remains in this stage of growth is determined by genetics. The longer the hair stays in the anagen phase, the longer it will grow.
A number of structural proteins (filaggrin, keratin), enzymes (e.g. proteases), lipids, and antimicrobial peptides contribute to maintain the important barrier function of the skin. Keratinization is part of the physical barrier formation ( cornification ), in which the keratinocytes produce more and more keratin and undergo terminal ...
Microscopy of keratin filaments inside cells. Keratin (/ ˈ k ɛr ə t ɪ n / [1] [2]) is one of a family of structural fibrous proteins also known as scleroproteins.It is the key structural material making up scales, hair, nails, feathers, horns, claws, hooves, and the outer layer of skin in vertebrates.

During hair growth, as follicle bulb cells swiftly transform into cortical or cuticle hair keratinocytes, approximately 50-100 keratin genes become activated at the transcriptional level. [8] However, this intricate process can be simplified into a few highly preserved gene families.
Keratin, type II cuticular Hb1 is a protein that in humans is encoded by the KRT81 gene. [5] [6] [7]The protein encoded by this gene is a member of the keratin gene family. As a type II hair keratin, it is a basic protein which heterodimerizes with type I keratins to form hair and nails.
