Using certain small proteins with a growth factor and specific materials can increase the creation of neurons from stem cells.

Skin stem cells are maintained by signals from nearby cells and vary in their ability to renew and mature.

The document concludes that understanding how adult stem and progenitor cells move is crucial for tissue repair and developing cell therapies.

Lack or blocking of SRD5a, a key component in hormone creation, can lead to conditions like pseudohermaphrodism and affect hair growth, bone mass, muscle strength, and reproductive health. More research is needed on its regulation from fertilization to adulthood.

Finasteride may increase erectile dysfunction risk in patients with benign prostatic hyperplasia.

Finasteride and dutasteride reduce neurosteroid production, possibly helping treat glioblastoma.

Finasteride slows down motherly behavior in first-time pregnant rats.

The enzymes 5α-reductase and 3α/β-hydroxysteroid oxidoreductase help create brain-active substances from progesterone and testosterone, which could be used for treatment, but more research is needed to ensure their safety and effectiveness.

The document concludes that managing side effects of MS therapies is crucial for treatment success and patient adherence.

3D cell-derived matrices improve tissue regeneration and disease modeling.

Finasteride doesn't affect erections much, but may decrease libido in men.

Exosomes help nerve fibers grow by affecting specific cell signaling pathways.

Bioluminescence imaging can track hair follicle cells and help study hair regrowth.

Researchers found two new genetic variants linked to Alzheimer's disease.

ERβ has potential in treating prostate cancer and neurodegenerative diseases, but human studies are needed before clinical use.

Finasteride safely treats hair loss without harming hormones or reproduction, but may slightly reduce sexual function.

Understanding and manipulating epigenetic changes can potentially lead to human organ regeneration therapies, but more research is needed to improve these methods and minimize risks.
