Tributyltin exposure causes sex changes, sterilization, and decline in the snail Ocinebrina aciculata, risking its extinction.

Memory T cells in the skin balance staying put and moving into the blood, clustering around hair follicles, and increasing in number after infection.

Methotrexate treats various disorders by inhibiting DNA synthesis, but careful monitoring is needed to avoid toxicity and manage side effects.

Finasteride helps hair growth but may cause sexual side effects.

Effective treatments for male pattern baldness include oral finasteride and topical minoxidil, while topical minoxidil is best for female pattern baldness.

Bioprinting could improve wound healing but needs more development to match real skin.

Stem cell self-renewal is complex and needs more research for full understanding.

The document concludes that more research is needed to better understand and treat primary cicatricial alopecias, and suggests a possible reclassification based on molecular pathways.

Use minoxidil for hair loss treatment; assess results after 6 months.

Aging causes skin stem cells to work less effectively.

Lupus affects the body and skin, causing joint pain and skin issues that can be treated with steroids and antimalarial drugs.

Androgens, like testosterone, are crucial for early testicular descent in rats.

Keratose, derived from human hair, is a non-toxic biomaterial good for tissue regeneration and integrates well with body tissues.

Liposomes improve drug delivery and reduce skin irritation in dermatology.

Male hormones affect COVID-19 severity and certain drugs targeting these hormones could help reduce the risk.

Tofacitinib helped regrow hair in most adolescents with alopecia areata, but more research is needed.

Different types of stem cells with unique roles exist in blood, skin, and intestines, and this variety is important for tissue repair.

Fat-derived stem cells show promise for skin repair and reducing aging signs but need more research for consistent results.

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

Tempol is safe and may prevent hair loss from brain radiotherapy.

Macrophages help heal nerves by aiding the maturation of Schwann cells and are important for nerve repair.

Silver nanoparticles coated with substances like PEG showed strong antibacterial effects and improved wound healing when used in hydrogels.

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.

Gene therapy with the Math1 gene helped regenerate balance-related cells and improve balance in mice.

Finasteride helps increase hair growth in men with hair loss.

Probiotic bacteria improved skin and hair health in aged mice.

Stem cell plasticity is crucial for wound healing but can also contribute to cancer development.

MicroRNA-302 helps improve the conversion of body cells into stem cells by blocking NR2F2.

The document describes how to tell different types of non-scarring hair loss apart by looking at hair and scalp tissue under a microscope.

Cytokeratin 19 and cytokeratin 15 are key markers for monitoring the quality and self-renewing potential of engineered skin.
