The use of neurogenic stem cells (NSCs) and neurogenic progenitor cells (NPCs) is one of the areas of brain and spinal cord lesions cell therapy. Intensive research of NSCs biology has revealed their tumor-tropic properties. Great migration potential and integration of NSCs in places of pathology in the central nervous system allows to consider their application as a means of targeted therapy of tumors. Antitumor properties of NSCs substantiate the development of treatment strategies for malignant gliomas using NSCs.
The aim was to study the effect of rat neurogenic cells supernatant (NCS) on the tumor-inducing ability of glioma 101.8 cells at the intracerebral implantation in rats.
Brain glioma 101.8 was modeling by intracerebral injection of 101.8-glioma cells suspension. NCS was received from whole rat brain tissue on 14th (E14) day of gestation.
Modification of 101.8-glioma cells suspension by means of incubation with NCS (0.02 and 0.1 mg/ml) reduced the tumor-inducing ability of tumor cells, postponing the time of tumor clinical manifestations debut and increasing the lifetime of experimental animals.
Under conditions of glioma induction with tumor cells, previously modified by NCS, cytotoxic activity of immune cells of tumor-bearing animals in MTT-test with allogeneic 101.8-glioma cells was increased.
