Figure 4.
KCC2 is upregulated in progenitor-derived neurons by 21 DIV. (a) Example images of KCC2 immunofluorescence in retinal progenitor-derived neurons at 21 DIV in all three insert conditions as marked. Scale bar is 50 µm. (b) Immunofluorescence measurements of relative KCC2 protein levels in all 3 conditions at 7 DIV and 21 DIV. (c) qPCR data showed >150-fold increase in KCC2 mRNA expression in progenitor-derived neurons from 7 DIV to 21 DIV in all three insert conditions, but no difference among the three insert conditions. (d) qPCR data show no significant differences in GABAA receptor subunit expression between 7 DIV and 21 DIV or among the three insert conditions. In (b–d) red lines indicate means; error bars, S.D.s; n.s. difference not significant; *p < 0.05. Immunofluorescence and qPCR data were normalized to values at 7 DIV with no insert.
