Hydrogels combined with extracellular vesicles and 3D bioprinting improve wound healing.

Trilostane may help delay epilepsy development by increasing certain brain chemicals.

3D imaging of skin biopsies offers better accuracy but is time-consuming and can't clear melanin.

Targeting and modifying the stem cell niche can improve regenerative therapies.

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

PRP helps skin heal, possibly through special cells called telocytes.

Dutasteride may help protect neurons and reduce inflammation in Parkinson's disease.

Metabolic signals and cell shape influence how cells develop and change.

Skin stem cells in hair follicles are important for touch sensation.

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.
