Figure 5From: Progesterone with Vitamin D Affords Better Neuroprotection against Excitotoxicity in Cultured Cortical Neurons than Progesterone AloneChanges in the morphology of neurons treated with VDH or PROG. Control group shows neuritic processes characteristic of neurons in vitro. The glutamate (0.5 µmol/L for 24 h) group shows the loss of neuronal processes and number of neurons. PROG (20 µmol/L) and VDH (100 nmol/L) alone rescued neurons independently, but this neuroprotective effect was more pronounced when neurons were exposed to their combination, that is, PROG (20 µmol/L) and VDH (20 nmol/L).Back to article page
