Environmental factors at different levels control hair stem cell activity, which could lead to new hair growth and alopecia treatments.

Inactive stem cells in hair follicles and muscles can avoid detection by the immune system.

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.

TNF family proteins are crucial for the development of skin features like hair, teeth, and mammary glands.

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

Research on epidermal stem cells has advanced significantly, showing promise for improved clinical therapies.

Neuregulin3 affects cell development in the skin and mammary glands.

Hair follicle stem cells help maintain skin health and could improve skin replacement therapies.

Horse skin stem cells combined with platelet-rich plasma improve skin healing.

KLF4 is important for maintaining stem cells and has potential in cancer treatment and wound healing.

A protein called EGFR protects hair follicle stem cells, and when it's disrupted, hair follicles can be damaged, but blocking certain pathways can restore hair growth.

The document suggests that activating autophagy might help with regeneration by removing old and damaged cells.

WNT10A helps esophageal cancer cells spread and keep renewing themselves.

Human liver cells stick to hair protein materials mainly through the liver's asialoglycoprotein receptor.

In vivo lineage labelling is better than in vitro methods for identifying and understanding stem cells.

Keratins help protect cells, aid in cancer diagnosis, and influence cancer behavior and treatment.

Understanding where cancer cells come from helps create better prevention and treatment methods.

Clim proteins are essential for maintaining healthy corneas and hair follicles.

The ZIP7 gene helps control zinc levels in cells by moving zinc from the Golgi apparatus to the cytoplasm.

The TGF-β family helps control how cells change and move, affecting skin, hair, and organ development.

A mother's PPARγ is crucial for preventing harmful milk that can cause inflammation and growth problems in babies.

Researchers found an RNA transcript that might help control a growth factor linked to tumor development.

Epimorphin, a protein, plays a key role in the development of hair follicles in human fetuses, but it doesn't help in maintaining the stem cell population of the follicular skin layer.

Keratin protein production in cells is controlled by a complex system that changes with cell type, health, and conditions like injury or cancer.

TGF-β is crucial for controlling stem cell behavior and changes in its signaling can lead to diseases like cancer.

TCDD disrupts skin stem cells, causing skin issues like chloracne.

Runx genes are important for stem cell regulation and their roles in aging and disease need more research.

A specific RNA molecule, circCOL1A1, affects the growth and quality of goat hair by interacting with miR-149-5p and influencing cell growth pathways.

The document concludes that while some organisms can regenerate body parts, mammals generally cannot, and cancer progression is complex, involving mutations rather than a strict stem cell hierarchy.

Cells lacking the Bax protein can outcompete others, leading to better tissue repair and hair growth.
