A progenitor cell is a biological cell that can differentiate into a specific cell type. Stem cells and progenitor cells have this ability in common. However, stem cells are less specified than progenitor cells.
In cell biology, precursor cells—also called blast cells—are partially differentiated, or intermediate, and are sometimes referred to as progenitor cells. A precursor cell is a stem cell with the capacity to differentiate into only one cell type, meaning they are unipotent stem cells .
These cells express Hnf6 and originate from pancreatic progenitor cells. They are peculiar as their morphology and characteristics is similar to that of the pancreatic progenitor cell. Ductal cell precursors express Hnf6 before developing into the mature ductal cell of the pancreas. [28]
Pluripotent stem cells undergo further specialization into multipotent progenitor cells that then give rise to functional cells. Examples of stem and progenitor cells include: [citation needed] Radial glial cells (embryonic neural stem cells) that give rise to excitatory neurons in the fetal brain through the process of neurogenesis.

In hematopoiesis, myeloid cells, or myelogenous cells are blood cells that arise from a progenitor cell for granulocytes, monocytes, erythrocytes, or platelets [1] [2] (the common myeloid progenitor, that is, CMP or CFU-GEMM), or in a narrower sense also often used, specifically from the lineage of the myeloblast (the myelocytes, monocytes, and ...
Many progenitor cells are also referred to as transit cells, [3] sometimes also called transit amplifying cells, the meaning of this term being that the transit cell may find a new sub-lineage but the number of resultant cells is strictly limited (although possibly very large, even trillions yet finite) and the lineage is terminated by cells ...
Osteochondroprogenitor cells are progenitor cells that arise from mesenchymal stem cells (MSC) in the bone marrow. They have the ability to differentiate into osteoblasts or chondrocytes depending on the signalling molecules they are exposed to, giving rise to either bone or cartilage respectively.
EndoMac progenitor cells are a type of endothelial-macrophage progenitor cells, more specifically a population of hemangioblasts from postnatal tissue. [1] [2] They were discovered by Australian researchers in the aorta of mice. [3]
