The study found that in Latin America, ancestry varies by location, influences physical traits, and affects how people perceive their own heritage.

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

Lgr5 is a marker for active, self-renewing stem cells in the intestine and skin, important for tissue maintenance.

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

Microspheres about 1.5 micrometers in size can best penetrate hair follicles, potentially reaching important stem cells.
