The study found that certain genes are important for hedgehog skin appendage development and immunity, with spines possibly evolving for protection and infection resistance.

Hair loss in male pattern baldness is linked to changes in immune cell behavior around hair follicles.

Researchers found 19 genes important for root hair growth in a plant called Arabidopsis.

The study showed that hair follicle stem cells can maintain and organize themselves in a lab setting, keeping their ability to renew and form hair and skin.

The conclusion is that CD90 is not a specific marker for fibroblast subtypes and better methods are needed to identify them.

Different signals work together to change gene activity and guide hair follicle stem cells to become specific cell types.

Poor maternal nutrition can lead to fewer wool follicles in Chinese Merino sheep.

Mutations in the SRD5A3 gene cause a new type of glycosylation disorder by blocking the production of a molecule necessary for protein glycosylation.

AP collagen peptides improve hair elasticity and gloss.

Touching hair can activate nearby nerve cells through signals from the hair's outer layer.

PI3K/Akt pathway is crucial for hair growth and regeneration.

TLR2 is important for hair growth and can be targeted to treat hair loss.

Tofacitinib is safe and effective for severe alopecia areata, but hair loss may return 2 months after stopping treatment.

Researchers found that certain RNA molecules might play a role in the growth of Cashmere goat hair.

COX2 and ATP synthase control the size of hedgehog spines.

Planarian regeneration begins with a specific gene activation caused by injury, essential for healing and tissue regrowth.

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.

Skin has specialized touch receptors that can tell different sensations apart.

Stress hormone corticosterone blocks a growth factor to slow down hair stem cell activity and hair growth.

Different scaffold patterns improve wound healing and immune response in mouse skin, with aligned patterns being particularly effective.

Key genes are crucial for Drosophila wing development and could be insecticide targets.

Spiny mice are better at regenerating hair after injury than laboratory mice and could help us understand how to improve human skin repair.

Transit-amplifying cells are crucial for tissue repair and can contribute to cancer when they malfunction.

Hes1 protein is important for hair growth and regeneration, and could be a potential treatment for hair loss.

Insect wax, especially its policosanol content, may help hair regrow by changing hair follicle phases and increasing nutrient supply.

KIF18B is important for correctly positioning cell division machinery in skin cells, affecting hair follicle development.

The peach gene pCTG134 helps control the interaction between auxin and ethylene hormones during fruit ripening.

Certain genes related to sulfur metabolism are more active during the growth phase of Cashmere goat wool, and melatonin might help this process.

A gene mutation in Lama3 is linked to a common type of hair loss.

A protein from fat-derived stem cells, DKK1, is linked to hair loss and blocking it may help treat alopecia areata.
