Influence of normal conditioned medium of astrocytes on the damaged neurons of cerebral hypoxia and reoxygenation in vitro

AIM: To study the nutritional role of the normal conditioned medium of astrocytes (NCMA) on the injured cerebral cortex neurons induced by cerebral hypoxia and reoxygenation in vitro. METHODS: The normal and damaged neurons induced by hypoxia and reoxygenation were cultured with normal conditioned medium of astrocytes (NCMA) after the cerebral cortical astrocytes and neurons of rats were isolated. The viability and survival rate of cultured neurons were investigated by MTT method. RESULTS: NCMA increased the viability and survival rate of cultured neurons. CONCLUSION: NCMA has nutritional and supporting roles on cultured neurons.
