What You Didn’t Know About Stem Cells

The mechanism behind hair growth is regulated by stem cells in the hair follicles. Several factors regulate hair growth, including the Foxc1 transcription factor, TGF-beta, and NFIB. This article will introduce these factors and discuss their effects on hair growth. If you are considering storing these cells, find a reliable stem cell center in Abu Dhabi.

Dermal papilla cells regulate the hair growth cycle:

Dermal papilla cells, or DPCs, are associated with hair follicle development and regulate the hair growth cycle. These cells express WNT10B, a transcription factor involved in hair growth and development. This protein regulates hair follicle growth through a paracrine signaling mechanism. It secretes activators into the upper epidermal compartments, where they act as a switch that triggers hair cycling.

Foxc1 transcription factor:

Studies have shown that FOXC1 plays a key role in maintaining hair follicle stem cells and regulating their quiescence. This transcription factor is also important in regulating bone morphogenetic protein (BMP) signaling and early cardiomyogenesis. In addition, it controls tight junctions, cell adhesion, and the actin cytoskeleton.

TGF-beta:

TGF-beta is a growth factor that controls hair follicle and cell division. Too much of it can kill the follicle, but not too little. This growth factor also communicates with other genes and triggers stem cells to divide and form a new follicle.

Dermal macrophages:

Dermal macrophages are a type of immune cell that has a wide range of functions in the skin. These cells are characterized by distinct gene expression and their ability to trigger the innate immune response. They can also suppress the growth of certain types of cancer. For example, macrophages can suppress the development of basal cell carcinoma. This cancer is induced by mutations in a protein called PTCH1, which leads to uncontrolled cell growth. Without macrophages, basal cell carcinoma grows rapidly.

Scarring:

Scarring alopecia is a condition caused by a slow-cycling stem cell in the hair follicle. These stem cells are located in the bulge region of the hair follicle. They produce secondary germ cells and transient amplifying cells that migrate upwards and downwards. When these cells die, the follicle breaks down, and hair falls out. This condition is known as primary cicatricial alopecia and is characterized by scarring of the hair follicle’s epidermal surface and hair follicles.
