Newly divided skin cells quickly move to join skin structures due to tissue tension and specific signals.

Stem cells regenerate tissues and their behavior varies by environment, suggesting the hematopoietic system model may need revision.

A specific group of skin stem cells was found to help maintain hair follicle cells.

Keratin proteins are essential for keeping the cells in the human colon healthy and stable.

In vivo lineage labelling is better than in vitro methods for identifying and understanding stem cells.

Different types of stem cells exist within individual skin layers, and they can adapt to damage, transplantation, or tumor growth. These cells are regulated by their environment and genetic factors. Tumor growth is driven by expanding, genetically altered cells, not long-lived mutant stem cells. There's evidence of cancer stem cells in skin tumors. Other cells, bacteria, and genetic factors help maintain balance and contribute to disease progression. A method for growing mini organs from single cells has been developed.

Activating Wnt in skin cells controls the number of hair follicles by directing cell movement and fate.

Regulatory T cells help heal skin and grow hair, and their absence can lead to healing issues and hair loss.

Phaeodactylum tricornutum extract helps hair follicle cells grow by activating the ERK1/2 pathway.

The ABCA4 gene protects hair follicle stem cells from toxic vitamin A byproducts.

Keratin proteins are crucial for healthy skin, but mutations can cause skin disorders with no effective treatments yet.

Three dogs with a rare skin condition improved with treatment.

SOX2 is crucial for skin cell function and hair growth, and it plays a role in skin cancer and wound healing.

Human beard hair medulla contains a unique and complex mix of keratins not found in other human tissues.

Hair matrix cysts are rare skin nodules with unique features, often needing surgical removal.

Cannabinoids like CBD and THC may help treat non-cancer skin diseases, but more research is needed.

Epidermal keratinocytes start wound healing and inflammation after schistosome infection.

A specific hair protein variant increases the spread of breast cancer and is linked to worse survival rates.

The study created hair-bearing skin models that lack a key protein for skin layer attachment, limiting their use for certain skin disease research.

Different types of long-lasting stem cells are responsible for the growth and upkeep of the mammary gland.

Skin's Regulatory T cells are crucial for maintaining skin health and could be targeted to treat immune-related skin diseases and cancer.

Skin stem cells remember past inflammation, helping them respond better to future injuries and possibly aiding in treating skin issues.

Disrupted sleep patterns can harm skin and hair cell renewal, but melatonin might help.

Obesity can weaken the skin's ability to fight infections because fat cells stop and reduce the infection-fighting properties of nearby stem cells.

Newborn mouse skin cells can grow hair and this process can be recreated in adult cells to potentially help with hair loss.

Scientists can grow human hair follicle stem cells in a lab without changing their nature, which could help treat hair loss.

Newly born mesenchymal cells quickly spread out in response to tissue tension during early development.

Hair follicles are valuable for regenerative medicine and wound healing.

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.

Vav2 and Vav3 proteins help control skin stem cell numbers and activity in both healthy and cancerous cells.
