Fat transplants using a patient's own fat can rejuvenate and repair tissues effectively.

Mechanical force is important for the first contact between skin cells and hair growth in mini-organs.

Activating Wnt in skin cells controls the number of hair follicles by directing cell movement and fate.

DNMT3A is crucial for healthy skin and hair growth.

Obesity can weaken the skin's ability to fight infections because fat cells stop and reduce the infection-fighting properties of nearby stem cells.

Microneedling is a safe and effective treatment for various skin conditions, often preferred for its fewer side effects and shorter recovery time.

Healthy mitochondria in skin cells are essential for proper hair growth and skin cell interaction in mice.

The conclusion is that skin and hair patterns are formed by a mix of cell activities, molecular signals, and environmental factors.

New materials that better mimic natural skin structure could improve healing, especially for chronic wounds.

Type 2 diabetes slows down skin and hair renewal by blocking important stem cell activation in mice.

Estrogen is important for keeping adult mouse nipple skin healthy by controlling certain cell signals.

Certain transcription factors are key in controlling skin stem cell behavior and could impact future treatments for skin repair and hair loss.

The new method using gene-modified stem cells and a 3D printed scaffold improved skin repair in mice.

Gene therapy shows promise for treating skin disorders and cancer, but faces technical challenges.

The Wnt signaling pathway is not a major factor in the development of keratoacanthoma, a type of skin tumor.

Exosomes could potentially enhance tissue repair and regeneration with lower rejection risk and easier production than live cell therapies.

Researchers found a new way to create hair-growing structures in the lab that can grow hair when put into mice.

Understanding the scalp's five-layer structure is crucial for better surgical outcomes and fewer complications.

Fully regenerating human hair follicles not yet achieved.

Understanding scalp anatomy is crucial for successful and safe scalp surgery.

Topical L-thyroxine may help with wound healing and hair growth but should be used short-term due to potential risks.

Fat tissue under the skin affects hair growth and aging; reducing its inflammation may help treat hair loss.

Adding human fat-derived stem cells to hair follicle grafts greatly increases hair growth.

Arrector pili muscle regulates hair follicle stem cells, DNA methylation needed for hair cycling, and Wnt/B-catenin signaling starts hair growth.

Triamcinolone acetonide helps scalp grafts grow hair successfully.

The new microwell device helps grow more hair stem cells that can regenerate hair.

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 2015 Hair Research Congress concluded that stem cells, maraviroc, and simvastatin could potentially treat Alopecia Areata, topical minoxidil, finasteride, and steroids could treat Frontal Fibrosing Alopecia, and PTGDR2 antagonists could also treat alopecia. They also found that low-level light therapy could help with hair loss, a robotic device could assist in hair extraction, and nutrition could aid hair growth. They suggested that Alopecia Areata is an inflammatory disorder, not a single disease, indicating a need for personalized treatments.

Prevelex, a polyampholyte, can create a cell-repellent coating on microdevices, which can be useful in biomedical applications like hair follicle regeneration.

Hair follicle melanocytes die during hair regression.
