Lizards can regrow their tails, and studying this process helps understand scar-free healing and limb regeneration.

The article concludes that better understanding gene regulation related to seasonal changes can offer insights into the mechanisms of seasonal timing in mammals.

A genetic region near the PAX1 gene is linked to a higher risk of scoliosis in females.

Wnt signaling helps control how brain stem cells divide and is important for brain repair after injury.

The document concludes that for hair and feather growth, it's better to target the environment around stem cells than the cells themselves.

Stem cell niches are adaptable and key for tissue maintenance and repair.

Intu gene is crucial for hair follicle formation by helping keratinocytes differentiate through primary cilia.

Celsr1 is crucial for skin cell alignment, while Celsr2 has little effect on this process.

CD4+ skin cells may be precursors to basal cell carcinoma.

The document concludes that while some organisms can regenerate body parts, mammals generally cannot, and cancer progression is complex, involving mutations rather than a strict stem cell hierarchy.

Hair follicles in mutant mice self-organize into ordered patterns within a week.

Dermal fibroblasts have adjustable roles in wound healing, with specific cells promoting regeneration or scar formation.

A calf in Scotland likely had Schmallenberg virus from its mother.

Eph receptors and ephrins may be promising targets for treating diseases, but more understanding is needed for effective and safe therapies.

CD99 is highly present in certain skin cells and could help treat skin conditions.

Stem cell niches are crucial for regulating stem cell behavior and tissue health, and their decline can impact aging and cancer.

Stem cell offspring help control their parent stem cells, affecting tissue health, healing, and cancer.

Stem cell niches support, regulate, and coordinate stem cell functions.

TGF-β signaling is crucial for stem cell maintenance, differentiation, and has implications for cancer treatment.

Macrophages help heal nerves by aiding the maturation of Schwann cells and are important for nerve repair.

S5αR inhibitors might help treat schizophrenia and other mental disorders but need more research.

β-Catenin signaling is involved in brain cell growth after injury and could be a therapy target.

Compartmentalized organization might be crucial for stem cells to effectively respond to growth or injury.

Environmental factors at different levels control hair stem cell activity, which could lead to new hair growth and alopecia treatments.

Manatee whiskers are specially adapted for touch in water.

Ephrins slow down skin and hair follicle cell growth.

Finasteride affects SRD5A2 gene pattern, possibly causing lasting side effects.

Humans have limited regenerative abilities, but new evidence shows the adult brain and heart can regenerate, and future treatments may improve this by mimicking stem cell environments.

Signals from skin cells controlled by Rac proteins help turn certain precursor cells into white fat cells.

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