Stem cells regenerate tissues and their behavior varies by environment, suggesting the hematopoietic system model may need revision.

Skin and hair renewal is maintained by both fast and slow cycling stem cells, with hair regrowth primarily driven by specific stem cells in the hair follicle bulge. These cells can also help heal wounds and potentially treat hair loss.

Some wound-healing cells can turn into fat cells around new hair growth in mice.

Hair loss and aging are caused by the breakdown of a key protein in hair stem cells.

Newborn mouse skin cells can grow hair and this process can be recreated in adult cells to potentially help with hair loss.

Researchers created a fully functional, bioengineered skin system with hair from stem cells that successfully integrated when transplanted into mice.

Hair follicle stem cells can turn into various cell types and help repair nerves.

Sonicated platelet-rich plasma boosts hair growth by activating stem cells.

MicroRNA-205 helps hair grow by changing the stiffness and contraction of hair follicle cells.

Hair follicles are valuable for regenerative medicine and wound healing.

FOL-026 peptide can help repair blood vessels and promote growth, offering potential treatment for vascular diseases.

Hoxc genes control hair growth through Wnt signaling.

Wounds heal without scarring in early development but later result in scars, and studying Wnt signaling could help control scarring.

Understanding different types of skin cells, especially fibroblasts, can lead to better treatments for wound healing and less scarring.

Drosha and Dicer are essential for hair follicle health and preventing DNA damage in skin cells.

WNT10A helps esophageal cancer cells spread and keep renewing themselves.

Scientists created early-stage hairs from mouse cells that grew into normal, pigmented hair when implanted into other mice.

Skin's epithelial stem cells are crucial for repair and maintenance, and understanding them could improve treatments for skin problems.

Reducing FOXA2 in skin cells lowers their ability to grow hair.

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

Different types of stem cells exist within individual skin layers, and they can adapt to damage, transplantation, or tumor growth. These cells are regulated by their environment and genetic factors. Tumor growth is driven by expanding, genetically altered cells, not long-lived mutant stem cells. There's evidence of cancer stem cells in skin tumors. Other cells, bacteria, and genetic factors help maintain balance and contribute to disease progression. A method for growing mini organs from single cells has been developed.

The skin protects the body and is constantly renewed by stem cells; disruptions can lead to cancer.

Hedgehog signaling helps keep hair follicle stem cells the same in both young and old human skin.

New treatments targeting skin stem cells show promise for skin repair, anti-aging, and cancer therapy.

Hair growth environment recreated with challenges; stem cells make successful skin organoids.

WNT7A gene expression is higher in early stages of androgenetic alopecia, showing the role of WNT pathway, apoptosis, and inflammation in the disorder.

Vav2 and Vav3 proteins help control skin stem cell numbers and activity in both healthy and cancerous cells.

Adult esophageal cells can start to become like skin cells, with a key pathway influencing this change.

Male hair loss is caused by inactive hair follicle stem cells.

The conclusion is that grasping how cells determine their roles through evolution is key, with expected progress from new research models and genome editing.
