• W236012912 abstract "Event Abstract Back to Event Effects of oxygen tension on neural cell development: in vitro and in vivo assays on differentiation of NE-4C neural stem cells Kornél Demeter1*, Anita Zadori1, Linda Varady1, Nóra Hádinger1, Viktor A. Agoston2, 3, Anna Gobl3, Zoltán Nagy2, Timea Kohidi1 and Emilia Madarasz1 1 Institute of Experimental Medicine, Semmelweis University , Hungary 2 Department Section of Vascular Neurology, Semmelweis University , Hungary 3 Hyperbaric Centre, Hungary Previously we demonstrated that the host environment modified the fate of stem cells implanted into the mouse forebrain. Brain lesions were shown to influence the survival and differentiation of stem cells. Therefore, we investigated the fate of GFP-4C neural stem cells in vitro and in vivo environments with different oxygen tensions. The consequences of hyperbaric oxygen (HBO) treatment (hyperoxia) were studied in vivo, in cold lesioned and intact host animals implanted with GFP-4C cells. The animals were exposed to hyperbaric oxygen (2 bar abs. for 90 minutes) on each day of the post-surgical week and were sacrificed 2, 4 or 6 weeks after the implantation. We examined the survival, differentiation and apoptotic death of implanted stem cells and the alterations in the volume of the grafts. The effects of low oxygen tension (hypoxia) were investigated on neural stem cells and their differentiating progenies, in vitro. Cell viability, the rate of neuron formation and apoptosis, as well as the gene expression patterns were compared between hypoxic (1% O2, 5% CO2, 94% N2) and normoxic cultures. The results demonstrate that hypoxic conditions do not affect the viability of non-committed neural stem cells, but modify the viability of committed neuronal precursors. Hyperbaric oxygen treatment results in an enhanced intracerebral survival and decreased proliferation of stem cells grafted into lesioned brain areas. These results suggest that oxygen tension appreciably influence survival, differentiation and gene expression of neural stem cells.
