Astrocytes are the major cell type in the mammalian brain. They provide a variety of supportive functions to their partner neurons in the central nervous system (CNS), such as neuronal guidance during development, nutritional and metabolic support throughout life . Astrocytes have also been implicated in various pathological processes . Impairment of normal astrocyte functions during stroke and other insults can critically influence neuron survival. Long-term recovery after brain injury, through neurite outgrowth, synaptic plasticity, or neuron regeneration, is also influenced by astrocyte surface molecule expression and trophic factor release . Numerous studies have demonstrated that astrocytes are among the most functionally diverse group of cells in the CNS . Much of what we have learned about astrocytes is from in vitro studies and astrocyte culture is a useful tool for exploring the diverse properties of this cell type.
iXCells Biotechnologies provides high quality Rat Astrocytes-hippocampal (RA-h), which are isolated from postnatal day 2 rat hippocampus and cryopreserved at P1, with >0.5 million cells in each vial. RA-h express GFAP and are negative for HIV-1, HBV, HCV, mycoplasma, bacteria, yeast, and fungi. They can further expand for 5 population doublings in Astrocyte Medium (Cat# MD-0039) under the condition suggested by iXCells Biotechnologies.
