5-alpha reductase inhibitors slightly increase the risk of sexual and mood side effects, and breast growth in men.

Targeting the actin cytoskeleton could improve skin healing and reduce scarring.

Resveratrol helps prevent finasteride-induced damage in male rats, improving reproductive function.

Finasteride may cause kidney damage.

Finasteride-treated male rats' offspring had altered glucose metabolism, potentially increasing diabetes risk.

Finasteride affects offspring's antioxidant enzymes in epididymis, possibly disrupting sperm maturation.

Father's finasteride use may affect son's fertility and testicular function.

Scientists created keratinocyte cell lines from human hair that can differentiate similarly to normal skin cells, offering a new way to study skin biology and diseases.

Frog skin cells need the protein desmoplakin for proper development and cell layer formation.

Maintain a natural, masculine look while rejuvenating the eye area with careful, tailored techniques.

Male pattern baldness may be caused by factors like poor blood circulation, scalp tension, stress, and hormonal imbalances, but the exact causes are still unclear.

The skin and mucous membranes can regenerate over the basement membrane after damage, using nearby surviving cells.

Integrin β1 is crucial for liver structure and function, preventing fibrosis.

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.

Stem cell niches support, regulate, and coordinate stem cell functions.

Skin problems can be caused or worsened by physical forces and pressure on the skin.

The document concludes that hair loss is common and can be treated with medications like minoxidil or surgical options, and it significantly affects people's psychological well-being.

The document explains the genetic causes and characteristics of inherited hair disorders.

Skin may help in getting rid of excess iron through the process of skin cell renewal.

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

The timing of when the gene Bmal1 is active affects aging and survival, with its absence during development, not adulthood, leading to premature aging.

Stress increases nerve fibers and immune cell activity in mouse skin, possibly worsening skin conditions.

Wool follicles are complex, involving interactions between different cell types and structures.

Products should be called 'sperm-safe' only after thorough, well-designed tests.

Steroid sex hormones activate matriptase in prostate cancer cells but not in breast cancer cells.

Keratins are important for skin cell health and their problems can cause diseases.

The document concludes that while there are promising methods to control CRISPR/Cas9 gene editing, more research is needed to overcome challenges related to safety and effectiveness for clinical use.

Stem cell niches are adaptable and key for tissue maintenance and repair.

Exosomes can improve skin health and offer new treatments for skin repair and rejuvenation.

Genetic mutations can cause hair growth disorders by affecting key genes and signaling pathways.
