Removing centrosomes from skin cells leads to thinner skin and stops hair growth, but does not greatly affect skin cell differentiation.

Damage to skin releases dsRNA, which activates TLR3 and helps in skin and hair follicle regeneration.

NF-κB is crucial for zebrafish heart repair, affecting heart cell growth and repair processes.

Tooth papilla cells can help regenerate hair follicles and grow hair.

Understanding gene expression in hair follicles can reveal insights into hair growth and disorders.

Basal cell carcinoma mostly starts from cells in the upper skin layers, not hair follicle stem cells.

Blood vessels and specific genes help turn cartilage into bone when bones heal.

Feather growth and regeneration involve complex patterns, stem cells, and evolutionary insights.

Skin has specialized touch receptors that can tell different sensations apart.

Hoxc genes control hair growth through Wnt signaling.

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

Skin organoids are a promising new model for studying human skin development and testing treatments.

Runx1 controls fat-related genes important for normal and cancer cell growth, affecting skin and hair cell behavior.

Stem cell differentiation is crucial for skin barrier maintenance and its disruption can lead to skin diseases.

Genetically modified sheep with more β-catenin grew more wool without changing the wool's length or thickness.

The mesenchyme can start hair growth, but the exact signal that causes this is still unknown.

Keratin proteins are crucial for hair structure and strength.

Hair follicles are complex, dynamic mini-organs that help us understand cell growth, death, migration, and differentiation, as well as tissue regeneration and tumor biology.

Epithelial stem cells are crucial for tissue renewal and repair, and understanding them could improve treatments for damage and cancer.

Hair growth phase and certain genes can speed up wound healing, while an inflammatory mediator can slow down new hair growth after a wound. Understanding these factors can improve tissue regeneration during wound healing.

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

The Sonic hedgehog pathway is crucial for new hair growth during mouse skin healing.

The document concludes that a better understanding of cell changes during wound healing could improve treatments for chronic wounds and other conditions.

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.

MicroRNA-214 is important for skin and hair growth because it affects the Wnt pathway.

A WNT10A gene mutation leads to ectodermal dysplasia by disrupting cell growth and differentiation.

The tumor suppressor gene FLCN affects mitochondrial function and energy use in cells.

The document concludes that the skin's immune system is complex, involving interactions with hair follicles, nerves, and microbes, and can protect or cause disease, offering targets for new treatments.

The extracellular matrix is crucial for controlling skin stem cell behavior and health.

Stem cell niches are adaptable and key for tissue maintenance and repair.
