The telogen phase of hair growth is active and important for preparing hair follicles for regeneration, not just a resting stage.

Macrophages help regrow hair by activating stem cells using AKT/β-catenin and TNF.

Hair grows faster in the morning and is more vulnerable to damage from radiation due to the internal clock in hair follicle cells.

PDGFA/AKT signaling is important for the growth and maintenance of certain skin fat cells.

Scientists turned mouse stem cells into skin cells that can grow into skin layers and structures.

Scientists created stem cells that can grow hair and skin.

Thymosin β4 promotes hair growth by activating stem cells in hair follicles.

The sebaceous gland has more roles than just producing sebum and contributing to acne, and new research could lead to better skin disease treatments.

Hormones significantly affect hair and oil gland function in the skin, and more research is needed on skin-related hormone disorders.

The document concludes that adult mammalian skin contains multiple stem cell populations with specific markers, important for understanding skin regeneration and related conditions.

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

Skin fat helps with body temperature control and has other active roles in health.

Wool follicles are complex, involving interactions between different cell types and structures.

Conditioned media from mesenchymal stem cell cultures could be a more effective alternative for regenerative therapies, but more research is needed.

Mammals might fail to regenerate not because they lack the right cells, but because of how cells respond to their surroundings, and changing this environment could enhance regeneration.

Circadian rhythms are crucial for stem cell function and tissue repair, and understanding them may improve aging and regeneration treatments.

DHEA stimulates skin oil glands and could help postmenopausal women, with potential for acne and excessive hair growth treatments.

Platelet-rich plasma may have some benefits in dermatology, but there's not enough evidence to widely recommend its use.

Researchers created a fully functional, bioengineered skin system with hair from stem cells that successfully integrated when transplanted into mice.

Fat tissue cells are a promising option for healing various diseases, but more research is needed to ensure they are safe and effective.

The circadian clock influences the behavior and regeneration of stem cells in the body.

Cells in hair follicles help create fat cells in the skin by releasing a protein called Sonic Hedgehog.

Hair grays due to oxidative stress and fewer functioning melanocytes.

The conclusion is that recognizing hair growth cycles can improve the precision of dietary and health assessments from hair analysis.

Different types of facial fat affect aging and treatment outcomes; more research is needed to enhance anti-aging procedures.

Cyclosporine A may help treat hair loss by blocking a protein that inhibits hair growth.

Oestrogens help maintain healthy skin, heal wounds, and may protect against skin aging and cancer.

Shrinking skin cancer increases the chance of cancer in nearby lymph nodes.

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

Hair follicle stem cells are a promising source for tissue repair and treating skin or hair diseases.
