Anticancer efficacy of allogeneic vaccine modified with progenitor neural cells supernatant in rats with glioma 101.8
The aim of the work was to investigate the antitumor efficacy of allogeneic tumor vaccine (ATV) modified with rat progenitor neural cell supernatant (RPNS) in rats with glioma 101.8. Materials and Methods: The study was performed on 74 white random-bred rats. ATV was developed on the basis of glioma...

| description | The aim of the work was to investigate the antitumor efficacy of allogeneic tumor vaccine (ATV) modified with rat progenitor neural cell supernatant (RPNS) in rats with glioma 101.8. Materials and Methods: The study was performed on 74 white random-bred rats. ATV was developed on the basis of glioma 101.8 cell suspension modified with RPNS (0.02 or 0.10 mg/ml). RPNS was prepared from suspension made from whole rat brain tissue on 14th (E14) day of gestation. Model of brain glioma 101.8 was reproduced by intracerebral injection of glioma 101.8 cell suspension. ATV was injected intraperitoneally in a volume of 0.2 ml per animal once on the 10th day after tumor transplantation. For survival analysis Kaplan — Mayer multiple assessments method was used. Cytotoxic activity of rat lymphocytes (effector cells) was evaluated in MTT-colorimetric test by determining the state of mitochondrial dehydrogenase enzymes in target cells (allogeneic glioma 101.8 cells). Results: Intraperitoneal administration of ATV modified with 0.10 mg/ml RPNS significantly increased mean survival time and median survival of glioma-bearing rats compared with unvaccinated group (MST (19.9 ± 2.4), 21.4 days; versus MST (14.6 ± 2.8); 14 days; p = 0.0002, Gehan’s — Wilcoxon test). Intraperitoneal administration of ATV modified with 0.10 mg/ml RPNS resulted in increased cytotoxic activity of immune cells of rats with glioma in vitro compared with this index in unvaccinated group (p = 0.026, U-Mann — Whitney test). Conclusion: Antitumor effect of vaccination with RPNS-modified ATV is realized via increased cytotoxic activity of immune cells, what could be used for further optimization of whole tumor cell vaccine. Key Words: allogeneic tumor vaccine, rat progenitor neural cells supernatant, glioma 101.8, mean survival time, lymphocyte cytotoxic function.
