Scientists have improved 3D models of human skin for research and medical uses, but still face challenges in perfectly replicating real skin.

Human hair follicles can be used to create stem cells that might help clone hair for treating hair loss or helping burn patients.

The document concludes that for hair and feather growth, it's better to target the environment around stem cells than the cells themselves.

Human hair follicle cells can be turned into stem cells that may help clone hair for treating hair loss or burns.

Inactive hair follicle stem cells help prevent skin cancer.

Stem cells help heal skin wounds by moving and changing roles, working with other cells, and needing more research on their activation and behavior.

Genetically modified stem cells from human hair follicles can lower blood sugar and increase survival in diabetic mice.

TGF-β is crucial for tissue repair and can cause diseases if not properly regulated.

Epidermal stem cells have various roles in skin beyond just maintenance, including forming specialized structures and aiding in skin repair and regeneration.

Hair follicle stem cells help maintain skin health and could improve skin replacement therapies.

Bioactive molecules show promise for improving skin repair and regeneration by overcoming current challenges with further research.

Hair loss in Androgenetic alopecia (AGA) is due to altered cell sensitivity to hormones, not increased hormone levels. Hair growth periods shorten over time, causing hair to become thinner and shorter. This is linked to miscommunication between cell pathways in hair follicles. There's also a change in gene expression related to blood vessels and cell growth in balding hair follicles. The exact molecular causes of AGA are still unclear.

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

Lymphatic vessels are important for skin repair and could affect skin disease treatments.

Skin cells release substances important for healing and fighting infection, and understanding these could improve skin disorder treatments.

New treatments for hair loss, including a compound called "ALRV5XR", platelet-rich plasma, and Adult Stem Cell-based therapy, are showing promise, but more trials are needed for confirmation.

Androgens affect bone and fat cell development differently based on the cells' embryonic origin.

The circadian clock plays a key role in hair growth and its disruption can affect hair regeneration.

Doxorubicin can block blood vessels from hair follicles, reducing skin tumor growth.

A new method helps grow skin cells from humans and mice more easily and quickly.

The new skin patch with human matrix and antibiotic improves wound healing.

A single medium, PRIME AIRLIFT, supports better human hair follicle formation in grafts.

Scaffold-based strategies show promise for regenerating hair follicles and teeth but need more research for clinical use.

PRP therapy helps skin heal and improve by promoting cell growth and repair.

The Wnt/β-catenin pathway is important for body functions and diseases, and targeting it may treat conditions like cancer, but with safety challenges.

Blocking the Wnt/β‐catenin pathway can speed up wound healing, reduce scarring, and improve cartilage repair.

Mitochondrial therapy and platelet-rich plasma therapy both stimulated hair regrowth in aging mice, with mitochondrial therapy showing similar effectiveness to plasma therapy.

Cord blood platelets may have promising future medical uses but need more research.

IL-6 from stem cells helps repair skin and grow hair.

Scientists identified a group of human skin cells with high growth and regeneration potential.
