Astrocytes are the most abundant cell type in the central nervous system (CNS) and they provide a variety of vital functions for the CNS including: establishment and regulation of the blood brain barrier, functional support for neuronal transmission, survival of neurons, anti-inflammatory responses and wound repair . Astrocytes have also been implicated in various pathological processes such as reactive gliosis . 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 . Rat astrocytes-adult (RA-a) are a useful in vitro model for studying adult glial function and the molecular mechanisms of CNS diseases such as ischemic stroke and multiple sclerosis.
iXCells Biotechnologies provides high quality Rat Astrocytes-adult (RA-a), which are isolated from adult rat brain and cryopreserved at P1, with >0.5 million cells in each vial. RA-a 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.
