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.

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

The conclusion is that the nuclear lamina and LINC complex in skin cells respond to mechanical signals, affecting gene expression and cell differentiation, which is important for skin health and can impact skin diseases.

Hair growth can be stimulated by combining certain skin cells, which can rejuvenate old cells and cause them to specialize in hair follicle creation.

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

Proretinal nanoparticles are a safe and effective way to deliver retinal to the skin.

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

Human skin cells with stem-like features can help create new hair follicles and sebaceous glands when combined with other cells.

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.

Changing the environment around stem cells could help tissue repair, but it's hard to be precise and avoid side effects.

The conclusion is that tissue structure is key for stem cell communication and maintaining healthy tissues.

UVB radiation harms hair growth and health, causing cell death and other changes in human hair follicles.

Topical treatments can deliver active molecules to skin stem cells, potentially helping treat skin and hair disorders, including skin cancers and hair loss.

Male and female skin differ in many ways, which could lead to gender-specific skin treatments.

MicroRNAs play a crucial role in skin and hair health, affecting everything from growth to aging, and could potentially be used in treating skin diseases.

The TGF-β family helps control how cells change and move, affecting skin, hair, and organ development.

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

TRP channels in the skin are important for sensation and health, and targeting them could help treat skin disorders.

Photobiomodulation helps reduce pain, lessen inflammation, heal wounds, and can be used in skin treatments. It also boosts hair growth in women with hair loss and may help fight microbes and prevent respiratory issues in COVID-19.

The article concludes that creating a detailed map of normal human skin at the single-cell level is important.

EGF controls hair growth by regulating hair follicles' growth phases.

Hair growth phase and certain genes can speed up wound healing, while an inflammatory mediator can slow down new hair growth after a wound. Understanding these factors can improve tissue regeneration during wound healing.

The nervous system helps control stem cell behavior and immune responses, affecting tissue repair and maintenance.

The study concluded that specific proteins are necessary to maintain the structure that holds epithelial cells tightly together.

Hox proteins help maintain keratinocyte identity by regulating miRNA expression.

NIPP1 is important for healthy skin and could help treat skin inflammation.

Zebrafish are useful for studying and developing treatments for human skin diseases.

Dandruff might be caused by changes in how hair follicles naturally release oils and an immune response to this imbalance.

The conclusion is that understanding how hair follicle stem cells live or die is important for maintaining healthy tissue and repairing injuries, and could help treat hair loss, but there are still challenges to overcome.

Scientists have improved 3D models of human skin for research and medical uses, but still face challenges in perfectly replicating real skin.
