Abstract
Aim: To assess the effect of oligomycin (Figure 1.a) as a tool for the induction of “chemical hypoxia” on an immortalized embryonic murine hippocampal cell-line (mHippoE-14) via the use of xCELLigence technology (that monitors real-time cellular proliferation and cellular events without the incorporation of labels), in the presence and absence of foetal bovine serum (FBS). Methods: xCELLigence monitored mHippoE-14 cells that were seeded at a density of 7.5 x 103 cells/well in 96-well plates and were allowed to grow for 24 h prior to being exposed to oligomycin (1 ug/mL) in the presence and absence of FBS. Parallel phase-contrast microscopy morphological studies were conducted. Results: FBS-deprivation led mHippoE-14 cells into a “pathopoietic phase”. Within this phase, oligomycin exerted a stable and statistically-significant decrease of the cellular index (Figure 1.b; green line) that was associated with both morphological and numerical changes in the exposed neuronal populations; the latter could allow for the use of oligomycin in the in vitro simulation of pro- and epiphenomena related to neuronal ischaemic injury. Conclusions: The highly-reproducible xCELLigence data generated by the exposure of mHippoE-14 to oligomycin have provided us with a number of important observations of technical interest that could allow for a more reliable implementation of the specific cell-line in the in vitro neuropathopoiesis attempts aiming to simulate ischaemic brain injury and related drug-screening assessment.
