Male pattern baldness may be caused by scalp pressure on hair follicles, which increases with age and leads to a cycle of hair loss. This process is not directly determined by genes.

Surgical removal of abnormal fat pads fixed the woman's eyelid issue caused by likely silicone injections.

Scalp expansion is an effective way to reconstruct the scalp with good cosmetic outcomes.

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

Composite flaps are better than muscle-only flaps for long-term skull coverage.

The document concludes that hair biology is complex and there are still unanswered questions about hair loss and follicle changes.

Blood-derived CD34+ cells speed up healing, reduce scarring, and regrow hair in skin wounds.

Hair restoration surgery techniques can effectively treat scalp deformities and have evolved to provide natural-looking results.

Muscle-only free flaps for skull coverage have more long-term complications than composite flaps.

Scientists are using clumps of special stem cells to improve organ repair.

The endobrow-midface lift is a safe and effective way to rejuvenate the upper face with minimal complications and rare temporary hair loss.

The technique improves facial aging signs with a low risk of complications and a recovery time of about 3 weeks.

Msx2 deficiency in mice leads to bone growth and organ development problems.

The study found that hair transplant surgery can be used to treat a rare condition that causes a band of hair loss, but surgeons should check for skull abnormalities first.

Old people have less hair because their hair follicles don't regenerate as well, not because of fewer stem cells, and a protein called follistatin might help reactivate hair growth.

Androgens affect bone and fat cell development differently based on the cells' embryonic origin.

Several genes, including Hox-7A, Stra6, and Lim-1, are involved in normal palate formation.

Mice without the vitamin D receptor have bone issues and other health problems, suggesting vitamin D is important for preventing various diseases in humans.

The secretions of mesenchymal stem cells could be used for healing without using the cells themselves.

Changing how mesenchymal stromal cells are grown can improve their healing abilities.

Msx and Dlx genes are crucial for development, controlling cell behaviors like growth and differentiation through their roles as gene regulators.

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

Exosomes could potentially enhance tissue repair and regeneration with lower rejection risk and easier production than live cell therapies.

Forehead modification greatly increases the perception of femininity and is a safe procedure.

Low doses of some substances can be beneficial, while high doses can be harmful or toxic.

Fibroblast growth factor receptor signaling controls cell development and repair, and its malfunction can cause disorders and cancer, but it also offers potential for targeted therapies.

Mutant CDP/Cux protein causes hair defects and reduced male fertility in mice.

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

Platelet preparations generally show positive effects on wound healing and facial rejuvenation, but more thorough research is needed to confirm their effectiveness.

Stem cells help repair tissue mainly by releasing beneficial substances, not by replacing damaged cells.
