Whiskers can form without sensory nerves or Foxd1, thanks to Meis2 in mesenchymal cells.

A gene network led by RSL4 is crucial for early root hair growth in response to cold in Arabidopsis thaliana.

The gene Ascl4 is not necessary for the development of hair, teeth, or mammary glands.

Immune cells are essential for early hair and skin development and healing.

Too much β-catenin activity can mess up the development of mammary glands and make them more like hair follicles.

Sweat gland development involves two unique skin cell programs and a temporary skin environment.

A specific genetic deletion in goats affects cashmere yield and thickness.

Proteins like aPKC and PDGF-AA, substances like adenosine and ATP, and adipose-derived stem cells all play important roles in hair growth and health, and could potentially be used to treat hair loss and skin conditions.

Some wound-healing cells can turn into fat cells around new hair growth in mice.

The Rotterdam Study updated findings on elderly health, focusing on heart disease, genetics, lifestyle effects, and disease understanding.

IL-17-producing γδ T cells help improve bone healing.

Researchers created human hair follicles using a new method that could help treat hair loss.

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

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.

Frontal fibrosing alopecia is linked to four genetic areas, especially the HLA-B*07:02 allele.

Hidradenitis suppurativa is caused by genetic factors, inflammation, bacteria, hormones, and lifestyle factors like obesity and smoking.

Securinine and ajmaline may effectively treat liver cancer, with securinine being less toxic to normal cells.

Air pollution (PM10) increases skin inflammation and aging by reducing collagen and may trigger a repair response in skin cells.

Beta-caryophyllene helps improve wound healing in mice, especially in females.

Certain bacteria and fungi are linked to healthy scalps and dandruff, suggesting that the scalp's microbial balance affects its health.

Hair can regrow after certain stem cells are lost because other stem cells can take over their role.

High proliferation and cell delamination drive early skin development, while later stages may not rely on cell division orientation.

Skin tumor regression is helped by retinoic acid signaling blocking Wnt signaling.

Researchers created rat liver stem cells that could help repair liver failure in rats and may be useful for studying human liver diseases.

A blood pressure drug, diltiazem, may also help treat influenza.

CRAC channels are crucial for the development and function of specialized immune cells, preventing severe inflammation and autoimmune diseases.

Shorter daylight increases hair growth in Cashmere goats.

Bird scales evolved from feathers, not reptile scales.

High lactate dehydrogenase activity is not necessary for the growth of squamous cell carcinoma.

The skin's basement membrane has specialized structures and molecules for different tissue interactions, important for hair growth and attachment.
