Fig 4. No difference in NPC apoptosis at the end of oxytocin treatment.

Scatter plots showing the proportion of apoptotic NPCs after treament with either 0, 100 pM, or 100 nM oxytocin for either 6 or 24 h, as noted. Apoptosis of NPCs was quantified with cleaved caspase-3 immunocytochemistry. 2-way ANOVA analysis did not show a significant difference either with oxytocin treatment (F (2,12) = 0.21, p = 0.81, η² = 0.03), time (F (1, 12) = 2, p = 0.18, η² = 0.14) or a treatment*time interaction (F (2, 12) = 0.043, p = 0.96, η² = 0.006). Data are expressed as mean ± S.E.M from three biologically independent NPC cultures.
