Effects of GM-CSF on the neural progenitor cells

Neuroreport

Abstract

Granulocyte macrophage colony stimulating factor (GM-CSF) is a potent hematopoietic cytokine, which stimulates stem cell proliferation in the bone marrow. We now report that GM-CSF receptors expressed on neural progenitor cells and can mediate a biological response in cells to treat with GM-CSF treated neural progenitor cells exhibited a proliferative response and a marked decrease in terminal differentiation to mature neuron or astrocytes. GM-CSF treatment also suppressed neural progenitor cell apoptosis. These findings suggest that GM-CSF can stimulate the proliferation and inhibit the apoptosis of neural progenitor cells to expand the progenitor population, and that GM-CSF has a potential role in neural development or repair.

Adult Stem Cells

Adult stem cells reside in unique niches that provide vital cues for their survival, self-renewal, and differentiation. They hold great promise for use in tissue repair and regeneration as a novel therapeutic strategies. Here is the latest research.

Astrocytes

Astrocytes are glial cells that support the blood-brain barrier, facilitate neurotransmission, provide nutrients to neurons, and help repair damaged nervous tissues. Here is the latest research.

Astrocytes in Repair & Regeneration

Astrocytes are glial cells found within the CNS and are able to regenerate new neurons. They become activated during CNS injury and disease. The activation leads to the transcription of new genes and the repair and regeneration of neurons. Discover the latest research on astrocytes in repair and regeneration here.

Apoptosis

Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis
