Porcine acellular dermal matrix helps hair growth by boosting specific proteins and signals.

Human skin can make serotonin and melatonin, which help protect and maintain it.

Hair color production in mice is closely linked to the hair growth phase and may also influence hair growth itself.

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.

Human skin cells produce proenkephalin, which changes with environmental factors and skin diseases.

Testosterone may slow down wound healing and increase inflammation.

Organotypic culture systems can grow skin tissues that mimic real skin functions and are useful for skin disease and hair growth research, but they don't fully replicate skin complexity.

Light therapy using helium-neon lasers can help restore skin color in vitiligo by promoting skin cell growth and movement.

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

The patch assay can create mature hair follicles from human cells and may help in hair loss treatments.

Skin cell-derived vesicles can help heal skin injuries effectively.

Hair follicle stem cells need all reprogramming factors to become pluripotent.

Burn scars form abnormally due to changes in wound healing, and more research is needed to improve treatments.

Sebalgukhwa-san (SGS) can help treat hair loss without liver toxicity.

Cells from a skin condition can create new hair follicles and similar growths in mice, and a specific treatment can reduce these effects.

Prdm1 is necessary for early whisker development in mice but not for other hair, and its absence changes nerve and brain patterns related to whiskers.

Platelet-rich plasma may have some benefits in dermatology, but there's not enough evidence to widely recommend its use.

Different species and human skin models vary in their skin enzyme activities, with pig skin and some models closely matching human skin, useful for safety assessments and understanding the skin's protective roles.

Immune cells are essential for early hair and skin development and healing.

Non-immune dermal cells dominate, epidermal cells increase after day 9, and certain immune cells persist beyond inflammation in wound-induced hair follicle regeneration.

Vesicles from irradiated mouse cheek skin help cells survive radiation.

The study identified unique genes in hair follicle cells and their environment, suggesting these genes help organize cells for hair growth.

Human skin can provide stem cells for tissue repair and regeneration, but there are challenges in obtaining and growing these cells safely.

Both cell and non-cell parts are important for rat whisker follicle regrowth.

Blocking testosterone speeds up wound healing in males.

Blocking testosterone speeds up wound healing in males.

Hormones and stretching both needed for nipple area skin growth in mice.

Injectable platelet-rich fibrin has improved healing and regeneration in various medical fields and can be more effective than previous treatments.

Understanding how baby skin heals without scars could help develop treatments for adults to heal wounds without leaving scars.

Bioengineering can potentially treat hair loss by regenerating hair follicles and cloning hair, but the process is complex and needs more research.
