Hair follicles repair 3D injuries using a 2D healing process.

Older hair follicle stem cells have a reduced ability to renew themselves, leading to more hair loss.

Some medications can improve skin conditions, while lifestyle factors like smoking and drinking may worsen them; treatments like monoclonal antibodies and imiquimod cream show promise for certain skin diseases.

The pituitary gland functions normally even after losing most SOX2+ stem cells.

Stem cell self-renewal is complex and needs more research for full understanding.

The niche environment controls stem cell behavior and plasticity, which is important for tissue health and repair.

Removing a specific gene in certain skin cells causes hair loss on the body by disrupting normal hair development.

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.

Hair follicles are complex, dynamic mini-organs that help us understand cell growth, death, migration, and differentiation, as well as tissue regeneration and tumor biology.

Wnt signaling is vital for cell growth, development, and cancer research.

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

Certain inhibitors slow down plant growth by causing early cell specialization without changing the cell development pattern.
