AXR3 and SHY2 genes control the growth and timing of root hair development in plants.

Different types of stem cells in hair follicles play unique roles in wound healing and hair growth, with some stem cells not originating from existing hair follicles but from non-hair follicle cells. WNT signaling and the Lhx2 factor are key in creating new hair follicles.

New research suggests that skin cell renewal may not require a special type of cell previously thought to be essential.

Using CDK inhibitors on rats showed a reduction in chemotherapy-caused hair loss, but later experiments could not repeat these results.

Humans lost body hair relatively recently in evolution.

Silver can help prevent and treat infections but its effectiveness varies and should be weighed against costs and side effects.

Stem cell self-renewal is complex and needs more research for full understanding.

Palliative chemotherapy is cost-effective for advanced gastric and colorectal cancer but not clearly for pancreatic-biliary cancer.

Keratinocytes help heal skin wounds by interacting with immune cells and producing substances that kill pathogens.

Telogen effluvium is a common type of hair loss that can resolve on its own or become chronic, with treatment depending on early diagnosis.

Skin aging is due to impaired stem cell mobilization or fewer responsive stem cells.

Too much androgen can cause hair loss; finasteride may help.

The document concludes that adenosine receptor agonists have potential for treating various conditions, but only a few are approved due to challenges like side effects and the need for selective activation.

Some viruses can cause cancer by changing cell processes and avoiding the immune system; vaccines and targeted treatments help reduce these cancers.

Vitamin D is important for skin health and may affect conditions like psoriasis and hair loss, but more research is needed to understand its role fully.

Modern science supports the use of some Ayurvedic plants for health, as ancient practices suggested.

Different types of stem cells with unique roles exist in blood, skin, and intestines, and this variety is important for tissue repair.

Stem cells in the hair follicle are regulated by their surrounding environment, which is important for hair growth.

Different types of stem cells and their environments are key to skin repair and maintenance.

Skin grafts on mice can cause an immune response leading to hair loss, useful for studying human hair loss conditions.

Alopecia areata significantly lowers the quality of life, especially in emotional and mental health aspects.
