Progenitor cell

A **progenitor cell** is a partially differentiated cell that arises from stem cells and has a limited capacity to divide before differentiating into one or more specialized cell types. Progenitor cells are further along the differentiation pathway than stem cells and typically possess restricted potency—usually oligopotent or unipotent. They play essential roles in tissue maintenance, regeneration, and development, being present in many organs such as bone marrow (hematopoietic progenitors), brain (neural progenitors), and muscle (muscle satellite cells)[1][3][5]. Progenitor cells are not a singular molecular entity but represent a functional category within cell biology. In disease, certain progenitor cell populations may serve as cells of origin in cancers, particularly in specific subtypes of breast cancer[2][4]. **Note:** "Progenitor cell" is not a specific molecular target or receptor and should not be used as a primary therapeutic target identifier in databases or structured biomedical resources[1][2][5].
