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.

A deficiency in the TTC7A gene causes immune problems, gut issues, and hair loss.

Skin organoids from stem cells could better mimic real skin but face challenges.

Researchers created rat liver stem cells that could help repair liver failure in rats and may be useful for studying human liver diseases.

Grouping certain skin cells together activates a growth pathway that helps create new hair follicles.

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

A new 3D culture system helps grow and study mouse skin stem cells for a long time.

Fat cells are important for tissue repair and stem cell support in various body parts.
