Higher testosterone harms sperm motility, while higher estradiol improves sperm survival.

Cryopreserved mouse whisker follicles can grow hair when transplanted into nude mice.

Operative hysteroscopy is still the main treatment for Asherman syndrome, but more research is needed on post-surgery methods.

Hair cell cloning could potentially rejuvenate shrinking hair follicles, allowing for lifelong hair maintenance.

Storing nanofat at -20°C for 7 days does not harm its ability to regenerate.

Green tea component EGCG helps keep rat skin grafts viable longer.

Muse cells keep their special features and can become different cell types even after being frozen and thawed three times.

Umbilical cord blood is a valuable source of stem cells for medical treatments, but its use is less common than other transplants, and there are ethical issues to consider.

The study found that the quality of cord blood units remains consistent before freezing and after thawing, indicating that attached tube segments reliably represent the graft's properties.

Using special stem cells, we can create new hair follicles, potentially making hair restoration easier and more affordable.

Freezing and storing special stem cells from hair follicles keeps their ability to grow hair and turn into different cell types.

Young mice's hair follicle stem cells are best for turning into heart muscle cells.

HAP stem cells can repair nerves and spinal cords by becoming Schwann cells.

Medical treatments like chemotherapy and radiotherapy can harm sperm production, so freezing sperm before treatment is important for men who want children later.

Adult mesenchymal stem cells can help regenerate tissues and are promising for healing bones, wounds, and hair follicles.

Transplanting skin cells is a safe, effective, and affordable treatment for vitiligo.

PRP is a safe natural treatment that improves skin by reducing wrinkles and enhancing texture for up to 4 months.

PRP treatment showed no hair regrowth improvement after the first application in patients with alopecia.

The document concludes that stem cell therapies lack solid proof of effectiveness, except for blood system treatments, and criticizes the ethical issues and commercial exploitation in the field.

The document concludes that better targeted treatments are needed for wound healing, and single-cell technologies may improve cell-based therapies.

Stem cells are crucial for skin repair and new treatments for chronic wounds.

Certain cells from hair follicles can create new hair and contribute to hair growth when implanted in mice.
