The Asiatic lion has very low genetic diversity and unique genetic traits, highlighting the need for its conservation.

Goat skin changes with the seasons due to genes affected by daylight and hormones.

Goat skin adapts to seasonal changes through genes that respond to daylight length, affecting hormone levels and potentially making skin cells light-sensitive.

FGFR2 signaling controls Merkel cell formation in different skin regions.

Alopecia areata involves immune activation in the scalp, suggesting treatments targeting TH1, TH2, and IL-23 pathways.

D-OCT shows increased blood vessel growth in response to tissue damage in Frontal Fibrosing Alopecia and is useful for diagnosis and monitoring.

The created skin model with melanoblasts improves the study of skin color and offers an alternative to animal testing.

Testosterone affects androgen receptors and lipid storage in cells, while DHEA does not convert to testosterone or affect these receptors in the same way.

PRC1 influences skin stem cell development by both turning genes on and off, affecting hair growth and skin cell types.

Blocking JAK-STAT5 signaling in mice leads to hair growth.

Sirolimus and propranolol may reduce abnormal cell growth and improve lymphatic malformations in children.
