It is well evident that the embryonic stem cells ESCs are pluripotent, can differentiate into all the three germ layers namely ectoderm, mesoderm and endoderm and into odd cell types present in the body, are immortal, can expand cell progenitors large numbers in vitroand are genetically stable over long periods in culture.

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. Progenitor cells can only differentiate into their "target" cell type. Controversy about the exact definition remains and the concept is still evolving.

Types of progenitor cells - Neural progenitor cells. Every cell in the human body, and that of other mammals, originates from stem cell precursors. Progenitor cells are descendants of stem cells that then further differentiate to create specialized cell types. There are many types of progenitor cells throughout the human body. Each progenitor cell is only capable of differentiating into cells that belong to the same tissue or organ. Some progenitor cells have one final target cell that they differentiate to, while others have the potential to terminate in more than one cell type. Stem cells share two qualifying characteristics. Firstly, all stem cells have the potential to differentiate into multiple types of cells. Secondly, stem cells are capable of unlimited self-replication via asymmetric cell division , a process known as self-renewal. There are two broad categories of stem cells found in all mammals.

OCT-4 biology has confused stem cell biologists as they failed to discriminate between various transcripts of Oct-4 and this has led to a lot of mix-up 42cell progenitors,

The dynamics of haematopoietic stem cell differentiation and the hierarchy of oligopotent stem cells in the bone marrow remain controversial. Here we dissect haematopoietic progenitor populations at single cell resolution, deriving an unbiased reference model of transcriptional states in normal and perturbed murine bone marrow.

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. In embryology , precursor cells are a group of cells that later differentiate into one organ. However, progenitor cells are considered multipotent. Due to their contribution to the development of various organs and cancers, precursor and progenitor cells have many potential uses in medicine. There is ongoing research on using these cells to build heart valves, blood vessels, and other tissues by using blood and muscle precursor cells.

Cell progenitors

Essentially, progenitor cells have been described as stem cell descendants with the limited ability to self-renew, proliferate, and give rise to more specialized cells. In the human body, the number of progenitors only makes up a minor proportion of the total population of cells. They have been shown to reside in various tissues in the body where are capable of differentiating into one or more lineages. Because of their capacity for self-renewal, proliferation, and differentiation, progenitor cells also play an important role in repair and regenerative processes. For this reason, they are described as intermediates between stem cells and the more specialized and functional cells of the body. Moreover, they contain a limited number of organelles involved in such functions as cell development and division. As mentioned, progenitor cells can be found in different body tissues.
