Astrocytes are the most abundant cell type in the brain and play an important role in regulating levels of extracellular ions and neurotransmitters, regulating synaptic activity and maintaining glutamate homeostasis, as well as maintaining the integrity of the blood-brain barrier. After trauma or infection, astrocytes are rapidly activated to form reactive astrocytes characterized by hyperplasia, hypertrophy, and high expression of intermediate filament proteins (including gliofibrillary acidic protein, vimentin, and nestin). Studies have shown that reactive astrocytes have both neurotoxic and neurotrophic effects. Shenzhen Cell Valley can provide the whole process services from neural stem cell differentiation Astrocytes, Astrocytes purification, quality control to release, with high product purity, quality control, high safety, scientific research cooperation with scientific research institutes, medical institutions, enterprises, etc., for the pre-clinical scientific research of Astrocytes. Innovative breakthrough to provide solutions.
