Cell aging can be both good and bad for tissue repair.

Melatonin helps Cashmere goats grow more hair by affecting certain genes and cell pathways.

Visible light can improve skin disorders and hair loss, but more research is needed to understand long-term effects.

Researchers developed a mouse model that successfully mimics the bladder damage seen in humans after radiation therapy.

Tacrolimus causes fewer acute rejections than cyclosporin A in kidney transplants but doesn't necessarily improve kidney function after one year; cardiovascular risks and side effects vary between the two drugs.

Researchers developed a method to grow hair follicles using special beads that could help with hair loss treatment.

Zouboulis syndrome is a rare condition that helps diagnose monosomy 18p early.

Hair is a complex organ, and understanding its detailed structure and growth phases is crucial for analyzing substances within it.

The document reports unique growth lines in a child after Stevens-Johnson syndrome, skin reaction from parsnips and sun in a girl, and itchy skin with xanthomas in a boy with Alagille syndrome.

New drugs for rheumatoid arthritis show improvement but have side effects and are not a cure.

The document concludes that permanent hair loss conditions are complex, require early specific treatments, and "secondary permanent alopecias" might be a more accurate term than "secondary cicatricial alopecia."

Monotreme hair structure and protein distribution are similar to other mammals, but their inner root sheath cornifies differently, suggesting a unique evolution from reptile skin.

The document reports findings on genetic research, including ethical concerns about genome editing, improved diagnosis of mitochondrial mutations, solving inherited eye diseases, confirming gene roles in epilepsy, linking a gene to aneurysms, and identifying genes associated with age-related macular degeneration.

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.

The extracellular matrix affects where tumors can start in the body.

Thallium, mercury, selenium, and colchicine strongly cause hair loss.

A new method using a microfluidic device can prepare hair follicle germs efficiently for potential use in hair loss treatments.

Human skin cells produce proenkephalin, which changes with environmental factors and skin diseases.

Disrupting Smad4 in mouse skin causes early hair follicle stem cell activity that leads to their eventual depletion.

Testosterone therapy can help postmenopausal women with low sexual desire if monitored carefully.

A man developed rare complications after nose surgery, stressing the need for better prevention.

Rat dermal papilla cells have unique genes crucial for hair growth.

Some types of extracellular matrix can change how human skin cells grow but don't affect their basic functions.

Fat-related cells are important for initiating hair growth.

Hair loss occurs due to fewer papillary cells, smaller follicles, and shorter growth phases.

The skin protects the body and is constantly renewed by stem cells; disruptions can lead to cancer.

Foxi3 expression in developing teeth and hair is controlled by the ectodysplasin pathway.

Adding amber particles to polyamide fibers makes them suitable for medical textiles like compression socks.

Mechanical forces are crucial for shaping cells and forming tissues during development.

Some women with PCOS have rare genetic variants linked to the condition.
