Did you mean Stem Cell Populations?

GlossaryStem Cell Populations

groups of cells capable of self-renewal and differentiation

Stem cell populations refer to groups of stem cells that share similar characteristics and functions within a specific tissue or organ. These cells have the unique ability to self-renew and differentiate into various specialized cell types, playing a crucial role in tissue repair and regeneration. In the context of hair, stem cell populations in hair follicles are essential for the growth and cycling of hair, and their dysfunction can lead to conditions like alopecia.
