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

Brain hormones significantly affect hair color and could potentially be used to prevent or reverse grey hair.

Lizards can regrow their tails, and studying this process helps understand scar-free healing and limb regeneration.

Spiny mice are better at regenerating hair after injury than laboratory mice and could help us understand how to improve human skin repair.

Monoolein-alginate beads help heal wounds by controlling moisture and effectively delivering adenosine to the skin.

Different factors like pH, gel type, and chemical enhancers affect how well hydrocortisone gets into hair follicles, and less hydrated skin doesn't work well with the test method.

PSA levels are higher in women with PCOS, but FAI is a more accurate marker for diagnosis.

Current methods can't fully recreate skin and its features, and more research is needed for clinical use.

Fermented ginsenosides from kimchi bacteria may promote hair growth better than finasteride.

Sostdc1 controls the size and number of hair and mammary gland structures.

Infrared light can trigger drug release from gold nanoparticle carriers in hair follicles.

Researchers made stem cells from human hair follicle cells with better efficiency than from skin cells.

High levels of ERK activity are key for tissue regeneration in spiny mice, and activating ERK can potentially redirect scar-forming healing towards regenerative healing in mammals.

Mesenchymal Stem/Stromal Cells (MSCs) help in wound healing and tissue regeneration, but can also contribute to tumor growth. They show promise in treating chronic wounds and certain burns, but their full healing mechanisms and potential challenges need further exploration.

The document concludes that mouse models are crucial for studying hair biology and that all mutant mice may have hair growth abnormalities that require detailed analysis to identify.

Using a fractional laser can stimulate hair growth, but the intensity and duration of inflammation are crucial. Too much can cause ulcers and scarring. Lower beam energy and fewer treatments are recommended to avoid damage.

Fibroblast Growth Factor-9 (FGF-9) can help improve heart function in diabetic mice after a heart attack by reducing inflammation and harmful changes to the heart's structure.

Growing human skin cells in a 3D environment can stimulate new hair growth.

Rat vibrissae have sensory terminals with specific structures that help detect hair movements.

3D-printed mesoporous scaffolds show promise for personalized drug delivery with controlled release.

Centella asiatica extract may help promote hair growth by blocking a specific cell signaling pathway.

Keratinocytes from dog hair follicles can create a functional skin layer in a lab model, useful for dog skin therapy.

Scientists made structures that look like human hair follicles using stem cells, which could help grow hair without using actual human tissue.

Sex and sex hormones can affect brain inflammation in Parkinson's disease, with male mice being more affected and female mice showing a protective effect.

CCL5 is important for the hair growth potential of human dermal papilla cells.

This new method makes checking for female infertility less painful, less invasive, and doesn't use radiation.

Forehead creases are formed by a tight connection between the skin and muscle through dense fibers, with changes in skin thickness and fewer skin appendages near the creases.

Tet2 and Tet3 enzymes are essential for controlling hair growth by affecting DNA demethylation and gene expression in mice.

Three-dimensional culture helps dermal papilla cells grow new human hair follicles.
