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]
This molecule is one of the genes widely used now to reprogram adult non-stem cells into pluripotent stem cells. Since then, neural progenitor and stem cells have been isolated from various areas of the adult central nervous system, including non-neurogenic areas, such as the spinal cord, and from various species including humans.

Neural stem cells, which only divide symmetrically to produce more neural stem cells, transition gradually into radial glial cells. [5] Radial glial cells, also called radial glial progenitor cells, divide asymmetrically to produce a neuroblast and another radial glial cell that will re-enter the cell cycle. [5] [3]
Proneural genes in neurogenesis and gliogenesis pathway - Neural stem cells have the potential to generate all neural cell types, such as neuron (neuronal progenitor), astrocytes and oligodendrocytes (glial progenitors). The proneural gene expression is induced by neurogenic signals and results in the activation of neuronal-differentiation ...
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.
Oligodendrocyte progenitor cells (OPCs), also known as oligodendrocyte precursor cells, NG2-glia, O2A cells, or polydendrocytes, are a subtype of glia in the central nervous system named for their essential role as precursors to oligodendrocytes and myelin. [1] They are typically identified in the human by co-expression of PDGFRA and CSPG4.
Intermediate progenitor cells (IPCs) are a type of progenitor cell in the developing cerebral cortex. They are multipolar cells produced by radial glial cells who have undergone asymmetric division. IPCs can produce neuron cells via neurogenesis and are responsible for ensuring the proper quantity of cortical neurons are produced.
Stem cell research has been gaining traction as a possible method of treatment for various human diseases. One large subcategory of progenitor cells are neural precursor cells (NPCs), which consist of oligodendrocyte, astrocyte, and neuronal precursor cells. Once differentiation into these precursor cells occurs, fate restriction happens and ...
