According to WHO, 6.7 million people die from stroke every year. The search for new neuroprotective substances remains an urgent task.
The purpose of this study was to investigate the neuroprotective activity of factors of placental origin.
Materials and methods. Neuroprotective activity of media conditioned with cryopreserved placenta derived mesenchymal stem cells (MSCs), organotypic culture of placenta and placental extract was studied on in vitro models of glutamate excitotoxicity in rats` neural cells. Neural cells were cultured with placental factors without glutamate treatment, before and after glutamate treatment. Neural cells` metabolic activity was assessed by MTT test.
Results. Placental factors increase the MTT test indexes, prevent the toxic effect of glutamate on neural cells and promote their recovery. The thermolability of factors of placental origin and the effectiveness of various placental preparations are shown.
Conclusions. Conditional media of placenta derived MSCs, organotypic culture of the placenta and human placental extract have neuroprotective effect on rats` brain cells in vitro.

Keywords: placenta; mesenchymal stem cells; placental extract; neural cells; neuroprotective effect
