A progenitor cell is a type of cell that has the ability to differentiate into a specific type of cell but is more limited than a stem cell. Progenitor cells are often found in various tissues and play a crucial role in growth, repair, and regeneration. They can give rise to multiple cell types within a particular lineage, such as blood cells or neurons. Unlike stem cells, progenitor cells have a more defined role and are usually committed to becoming a specific cell type. They are essential in processes like tissue development and healing, helping to replace damaged or lost cells in the body.
