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

Modulating BMP activity changes the number, size, shape, and type of ectodermal organs.

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

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.

Low doses of some substances can be beneficial, while high doses can be harmful or toxic.

Men generally have more severe COVID-19 cases and higher death rates than women due to biological differences.

Different PIN proteins affect plant root hair growth by changing how auxin is transported.

Fibroblast growth factor receptor signaling controls cell development and repair, and its malfunction can cause disorders and cancer, but it also offers potential for targeted therapies.

The hydrogel with a 1:3 ratio of hydroxyethyl cellulose to hyaluronic acid is effective for delivering drugs through the skin to treat acne.

MIM is crucial for hair follicle formation and regeneration by controlling cilia formation and hedgehog signaling through its interaction with Cortactin and Src.

The conclusion is that the increasing use of drugs for lifestyle reasons is a complex issue influenced by corporate profit, consumer behavior, and the medicalization of everyday life, with potential negative effects on personal well-being.

The article concludes that the wool follicle is a valuable model for studying tissue interactions and has potential for genetic improvements in wool production.

Scientists turned rat thymus cells into stem cells that can help repair skin and hair.

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

Men, especially older ones with health issues like prostate cancer, may have worse COVID-19 outcomes and could benefit from therapies targeting male hormones.

Hair, teeth, and mammary glands develop similarly at first but use different genes later.

New treatments targeting specific genes show promise for treating keratin disorders.

Choosing the right model order in brain connectivity analysis can affect the detection of differences between healthy individuals and those with seasonal affective disorder.

Stress increases a factor in mice that leads to hair loss, and blocking this factor may prevent it.

Overexpressing Dsg3 in mice skin causes excessive cell growth and abnormal skin development.

Formyl-peptide receptor agonists could be new anti-inflammatory drugs.

MicroRNA-214 is important for skin and hair growth because it affects the Wnt pathway.

Scientists created stem cells that can grow hair and skin.

Removing both Atr and Trp53 genes in adult mice causes severe tissue damage and death due to DNA damage.

Prolactin affects hair growth and skin conditions, and could be a target for new skin disease treatments.

Trichoscopy is a useful, non-invasive way to diagnose different types of hair loss.

Lichen planus pigmentosus causes dark skin patches and is treated by avoiding triggers and using anti-inflammatory medications.

Newborn mouse skin cells can grow hair and this process can be recreated in adult cells to potentially help with hair loss.

Wnt signaling helps control how brain stem cells divide and is important for brain repair after injury.

Obesity increases the risk of developing polycystic ovary syndrome, and weight loss can improve the condition.
