Testosterone therapy is generally safe for transmen, improves sexual function, and has manageable health risks with proper monitoring.

Stem cell therapies show promise for treating various diseases but face challenges in clinical use and require better monitoring techniques.

Women with PCOS have more insulin resistance and are more likely to have heart-related health issues, with insulin resistance being a bigger factor than β-cell problems.

TGF-β signaling is crucial for stem cell maintenance, differentiation, and has implications for cancer treatment.

Stem cells are crucial for tissue growth, cancer treatment, and disease modeling, but challenges remain in clinical use.

Lgr5 is a marker for active, self-renewing stem cells in the intestine and skin, important for tissue maintenance.

Different types of skin cells play specific roles in development, healing, and cancer.

Regulatory T-cells are important for healing and regenerating tissues in various organs by controlling immune responses and aiding stem cells.

Different types of stem cells exist within individual skin layers, and they can adapt to damage, transplantation, or tumor growth. These cells are regulated by their environment and genetic factors. Tumor growth is driven by expanding, genetically altered cells, not long-lived mutant stem cells. There's evidence of cancer stem cells in skin tumors. Other cells, bacteria, and genetic factors help maintain balance and contribute to disease progression. A method for growing mini organs from single cells has been developed.

Foxp3 is crucial for regulatory T cell function, and targeting these cells may help treat immune disorders.

The research identified various cell types in mouse and human teeth, which could help in developing dental regenerative treatments.

Hair grows faster in the morning and is more vulnerable to damage from radiation due to the internal clock in hair follicle cells.

Using human fat tissue derived stem cells in micrografts can safely and effectively increase hair density in people with hair loss.

Stem cells from hair follicles can safely treat hair loss.

Certain types of T cells are essential for healthy skin and play a role in skin diseases, but more research is needed to improve treatments.

Activin helps skin growth and healing mainly through stromal cells and affects keratinocytes based on its amount.

Researchers created a fully functional, bioengineered skin system with hair from stem cells that successfully integrated when transplanted into mice.

Human hair follicle cells can be turned into stem cells similar to embryonic stem cells.

Understanding how hair follicle stem cells work can help find new ways to prevent hair loss and promote hair growth.

Stem cells help repair tissue mainly by releasing beneficial substances, not by replacing damaged cells.

The study found that certain microRNAs are higher in the cells and lower in the fluid of women with a specific type of polycystic ovary syndrome, and one microRNA could potentially help diagnose the condition.

miR-22, a type of microRNA, controls hair growth and its overproduction can cause hair loss, while its absence can speed up hair growth.

Glutamine metabolism affects hair stem cell maintenance and their ability to change back to stem cells.

A new hydrogel with stem cells from human umbilical cords improves skin wound healing and reduces inflammation.

Researchers created rat liver stem cells that could help repair liver failure in rats and may be useful for studying human liver diseases.

The study suggests that motor neurons created from stem cells of patients with spinal and bulbar muscular atrophy show signs of the disease, including changes in protein levels and cell functions.

Activin B improves wound healing and hair growth by helping stem cells move using certain cell signals.

Using fat stem cells and blood cell-rich plasma together improves healing in diabetic wounds by affecting cell signaling.

Human alpha defensin 5 helps heal wounds, reduce bacteria, and grow hair on burned skin.

GLI2 increases follistatin production in human skin cells.
