Alexander the Great's engineers built a causeway using a natural sand bridge, some tiger moths avoid bats by mimicking toxic relatives' sounds, early metabolism and RNA enzymes support the ancient RNA world theory, and vitamin D is crucial for hair growth and its absence can cause baldness.

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

The PDGF/PDGFR pathway is a potential drug target with mixed success in treating various diseases, including some cancers and fibrosis.

The study identified unique genes in hair follicle cells and their environment, suggesting these genes help organize cells for hair growth.

Wnt signaling controls whether hair follicle stem cells stay inactive or regenerate hair.

Aging causes skin stem cells to work less effectively.

The document concludes that a better understanding of cell changes during wound healing could improve treatments for chronic wounds and other conditions.

Dermal fibroblasts have adjustable roles in wound healing, with specific cells promoting regeneration or scar formation.

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

We need more research to better understand human hair follicle stem cells for improved treatments for hair loss and skin cancer.

Phospholipase A2 is necessary for the correct placement of PIN proteins in plant roots, affecting root growth.

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

Sub3 is essential for fungus adherence but not for skin invasion.

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.
