Scarring alopecias are complex hair loss disorders that require early treatment to prevent permanent hair loss.

Hair follicle stem cells and skin cells show promise for hair and skin therapies but need more research for clinical use.

Environmental factors at different levels control hair stem cell activity, which could lead to new hair growth and alopecia treatments.

Scientists successfully created and transplanted bioengineered hair follicles that function like natural ones, suggesting a new treatment for hair loss.

Advanced human skin models improve drug development and could replace animal testing.

Humans have limited regenerative abilities, but new evidence shows the adult brain and heart can regenerate, and future treatments may improve this by mimicking stem cell environments.

Different types of fibroblasts play various roles in diseases and healing, and more research on them could improve treatments.

IL-18 signaling helps mature Tregs move into the thymus.

Fat-derived stem cells, platelet-rich plasma, and biomaterials show promise for healing chronic skin wounds and improving soft tissue with few side effects.

Bone-marrow and epidermal stem cells help heal wounds differently, with bone-marrow cells aiding in blood vessel formation and epidermal cells in hair growth.

Skin bacteria, specifically Streptococcus and Staphylococcus, help in hair regrowth after skin injury and speed up wound healing.

Genetically-altered adult stem cells can help in wound healing and are becoming crucial in regenerative medicine and drug design.

Lipocalin-Type Prostaglandin D2 Synthase (L-PGDS) is a protein that plays many roles in the body, including sleep regulation, pain management, food intake, and protection against harmful substances. It also affects fat metabolism, glucose intolerance, cell maturation, and is involved in various diseases like diabetes, cancer, and arthritis. It can influence sex organ development and embryonic cell differentiation, and its levels can be used as a diagnostic marker for certain conditions.

Scientists developed a system to study human hair growth using skin cells, which could help understand hair development and improve skin substitutes for medical use.

Hair follicle stem cells are key for hair and skin regeneration, can be reprogrammed, and have potential therapeutic uses, but also carry a risk of cancer.

Different connective tissue disorders have unique symptoms and treatments, with varying outcomes and often require ongoing care from a specialist.
