To date, the ideal progenitor cells have not been found or created.

The progenitor cells respond to factors in their environment.

Both types of fat cells were assumed to be related and come from the same progenitor cell type.

Some progenitor cells were found during research, and were isolated.

Progenitor cells are found in adult organisms and they act as a repair system for the body.

Hematopoietic progenitor cells are normally present in the blood at low levels.

It is expressed on the surface of many hematopoietic progenitor cells.

For one thing, biologists must determine that human brains harbor a similar population of progenitor cells.

However, the origin of these progenitor cells varies between regenerating systems.

When the children were a year old, the researchers used the fishhook again to examine stem and progenitor cells.

But a number of problems still must be solved before doctors can use the progenitor cells to repair damaged brains.

The continued research into the importance of endothelial progenitor cells may present novel therapeutic targets.

Endothelial progenitor cells do not appear to play an essential role in wound healing.

Hemopoietic growth factors regulate the differentiation and proliferation of particular progenitor cells.

Thus further research must be done to understand the factors that affect progenitor cell differentiation to treat Parkinson's disease.

It has also been attributed to an inhibitory activity on hematopoietic progenitor cells.

Many properties are shared by adult stem cells and progenitor cells.

Neurotrophins also induce differentiation of progenitor cells, to form neurons.

ID1 can be used to mark endothelial progenitor cells which are critical to tumor growth and angiogenesis.

This indicates that endothelial progenitor cells present novel therapeutic targets.

In biology, oligopotency is the ability of progenitor cells to differentiate into a few cell types.

Many important discoveries were made during this period, which led in part to the general conclusion that progenitor cells are required for most regenerative processes.

Over time, progenitor cells migrate out of the tissue onto the surface of the dish.

Erythropoietin is required for a myeloid progenitor cell to become an erythrocyte.

Vasculogenesis is the new production of a vascular network from mesodermal progenitor cells.
