Pig skin cells can turn into mesodermal cells but lose their ability to become neural cells.

Fat cells in the skin help start healing and form important repair cells after injury.

Aging causes sweat glands to shrink and move upward, leading to less elastic skin and more wrinkles.

Melanocyte stem cells in hair follicles are key for hair color and could help treat greying and pigment disorders.

Two main types of fibroblasts with unique functions and additional subtypes were identified in human skin.

Different types of skin cells play specific roles in development, healing, and cancer.

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

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

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

Skin fat has important roles in hair growth, skin repair, immune defense, and aging, and could be targeted for skin and hair treatments.

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.

Skin-derived stem cells can become various cell types, including germ cell-like and oocyte-like cells.

Scientists successfully grew new hair follicles in regenerated mouse skin using mouse and human cells.

Blood-derived CD34+ cells speed up healing, reduce scarring, and regrow hair in skin wounds.

The skin's dermal layer contains true stem cells with diverse functions and interactions that need more research to fully understand.

Skin spheroids with both outer and inner layers are key for regrowing skin patterns and hair.

Dermal stem cells help regenerate hair follicles and heal skin wounds.

The research found that different types of fibroblasts are involved in wound healing and that some blood cells can turn into fat cells during this process.

Sonic hedgehog signaling is crucial for hair growth and maintaining hair follicle identity.

Adult skin cell-based early-stage skin substitutes improve wound healing and hair growth in mice.

The research reveals how early embryonic mouse skin develops from simple to complex structures, identifying various cell types and their roles in this process.

The nucleus is key in controlling skin growth and repair by coordinating signals, gene regulators, and epigenetic changes.

Keratinocytes and adipose-derived stem cells can effectively heal difficult skin wounds.

Mice lacking fibromodulin have disrupted healing patterns, leading to abnormal skin repair and scarring.

Hair can regrow in large wounds through a process similar to how hair forms in embryos, and understanding this could lead to new treatments for hair loss or scarring.

Calcium is important for stem cell function and maintenance, especially in blood and skin cells.

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 document concluded that stem cells are crucial for skin repair, regeneration, and may help in developing advanced skin substitutes.

The study showed that hair follicle stem cells can maintain and organize themselves in a lab setting, keeping their ability to renew and form hair and skin.

Skin needs dermal β-catenin activity for hair growth and skin cell multiplication.
