Figure 4From: A refined in vitro model to study inflammatory responses in organotypic membrane culture of postnatal rat hippocampal slicesEffect of culture time prior to LPS exposure on LPS-induced IL-6 response. LPS was added to the medium after 7, 14 and 21 DIV; exposure time was 24 h. LPS evoked extensive secretion of IL-6 at all of the time points. Values are means ± SD (n = 6 in each group).Back to article page
