Developing hair follicles form from ring-shaped patterns, with future stem cells originating from the outer ring, not the upper layers, as previously thought.

Skin spheroids with both outer and inner layers are key for regrowing skin patterns and hair.

Merkel cells stabilize nerve endings in the skin, and they change independently of each other.

The tumor likely shows dual neural crest differentiation.

PrPC is important for neural differentiation in cattle and mouse embryonic stem cells.

Hair follicle stem cells can become motor neurons and reduce muscle loss after nerve injury.

Mice can grow new hair follicles after skin wounds through a process not involving existing hair stem cells, but requiring more research to understand fully.

Scientists created early-stage hairs from mouse cells that grew into normal, pigmented hair when implanted into other mice.

Human Schwann cells can be quickly made from hair follicle stem cells for nerve repair.

Higher concentrations of mouse embryo tissue extracts effectively turn hair follicle stem cells into neural cells.

Deleting the CD271 gene in mouse skin cells leads to disorganized skin and increased hair growth, suggesting CD271 is important for skin health.
