The research identified two types of keratinocytes in chicken scales: one for hard scales and another for soft skin, with similarities to human skin differentiation.

Older skin has higher cancer risk due to inflammation and stem cell issues.

Skin health and repair depend on the signals between skin stem cells and their surrounding cells.

The nucleus is key in controlling skin growth and repair by coordinating signals, gene regulators, and epigenetic changes.

Erbium glass laser treatment may help with skin remodeling, reduce inflammation, and improve skin cell maturation.

Bone Morphogenetic Proteins (BMPs) help control skin health, hair growth, and color, and could potentially be used to treat skin and hair disorders.

Mice without the vitamin D receptor are more prone to UV-induced skin tumors.

MicroRNAs are crucial for controlling skin development and healing by regulating genes.

The skin's dermal layer contains true stem cells with diverse functions and interactions that need more research to fully understand.

Mice lacking a key DNA methylation enzyme in skin cells have a lower chance of activating stem cells necessary for hair growth, leading to progressive hair loss.

A new staining method shows a special area in the hair's skin layer with lots of proteoglycans.

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.

Involucrin gene expression is controlled by specific proteins and signaling pathways.
