Both cells later produce one or two neural cells (N). 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. [1]
HDAC inhibitors (HDACi), such as valproic acid (VPA) and trichostatin A can promote proliferation of adult neurogenesis through the inhibition of HDAC activity, inducing differentiation of adult progenitor cells. [12] Neural-expressed HDACs interact with Tlx, an essential neural stem cell regulator, to suppress TLX target genes.
They are tripotent cells which can give rise to neurons, astrocytes and oligodendrocytes. An oligodendroglial progenitor cell, for example, gives rise to oligodendrocytes until its mitotic capacity is exhausted. [17] Some neural progenitor markers are capable of tracking cells as they undergo expansion and differentiation from rosettes to neurons.
The spatial location and temporal attributes of neural progenitor cells can influence if the cells form neurons or glial cells. Further differentiation is then controlled by extracellular conditions and cell signaling. [11] The exact conditions and stimuli necessary to differentiate neural progenitor cells into specific neural tissues such as ...
Neural stem cells differentiating to astrocytes (green) and sites of growth hormone receptor shown in red. There are two basic types of stem cell: adult stem cells, which are limited in their ability to differentiate, and embryonic stem cells (ESCs), which are pluripotent and have the capability of differentiating into any cell type.

In general, this means that a cell determined to differentiate into a brain cell cannot be transformed into a skin cell. Determination is followed by differentiation, the actual changes in biochemistry, structure, and function that result in specific cell types. Differentiation often involves a change in appearance as well as function. [18]
