Different types of skin fibroblasts have unique roles in skin health and disease.

Different types of skin cells and immune cells play a role in healing UV-damaged skin, with chronic UV exposure causing lasting damage to certain skin cells.

Nonpalmoplantar skin cells can be made to express keratin 9 by interacting with palmoplantar fibroblasts.

Skin fat plays a key role in immune defense and healing beyond just storing energy.

Skin heals with scars because only one type of fibroblast is used, not a mix.

Mouse skin fibroblasts vary in function and adaptability based on their environment.

Hedgehog signaling in skin cells is crucial for hair growth and skin healing, but needs to be balanced to avoid harmful effects like scarring and cancer.

Using your own skin cells can help repair aging skin and promote hair growth.

Mesenchymal stem cell proteins in a special gel improved healing of severe burns.

Aging causes changes in the scalp that can affect hair growth and lead to older-looking hair in women.

Hedgehog signaling in certain cells is crucial for hair growth during wound healing.

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.

Blocking β-catenin in skin cells improves hair growth during wound healing.

AcSDKP may help prevent skin and hair aging and promote their growth.

Skin and hair can regenerate after injury due to changes in gene activity, with potential links to how cancer spreads. Future research should focus on how new hair follicles form and the processes that trigger their creation.

New hair can grow from large wounds in mice, but less so as they age, involving reprogramming of skin cells and specific molecular pathways.

The skin's basement membrane has specialized structures and molecules for different tissue interactions, important for hair growth and attachment.

The document concludes that better targeted treatments are needed for wound healing, and single-cell technologies may improve cell-based therapies.

Reductive stress messes up collagen balance and alters cell signaling in human skin cells, which could help treat certain skin diseases.

Different lab conditions and light treatment methods change how human skin cells respond to light therapy.

Scientists can now grow hair-like structures in a lab using special 3D culture systems, which could potentially help people with hair loss or severe burns.

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

New treatments for skin and hair repair show promise, but further improvements are needed.

Current therapies cannot fully regenerate adult skin without scars; more research is needed for scar-free healing.

Gene network oscillations inside hair stem cells are key for hair growth regulation and could help treat hair loss.

A new liposome treatment helps heal deep burns on mice by improving hair regrowth and reducing scarring.

Mice can grow new hair follicles after skin wounds through a process not involving existing hair stem cells, but requiring more research to understand fully.

The study created hair-bearing skin models that lack a key protein for skin layer attachment, limiting their use for certain skin disease research.

Activating TLR9 helps heal wounds and regrow hair by using specific immune cells.

Exosomes could be effective for improving skin health and treating skin diseases.
