Patients with certain skin symptoms and high ANA titers should be monitored for potential systemic lupus.

Glutamine metabolism affects hair stem cell maintenance and their ability to change back to stem cells.

Advanced therapies like gene, cell, and tissue engineering show promise for hair regrowth in alopecia, but their safety and effectiveness need more verification.

Men are more likely to have severe respiratory viral infections like COVID-19 due to hormonal and genetic differences, while women generally have stronger immune responses.

Key genes linked to hair growth and cancer were identified in hairless mice.

Stem cells help remove dead cells to keep tissues healthy by balancing cell replacement and clearance.
