Week 15 WSM COs stained for the cortical layers' markers CTIP2 and SATB2. (WSM F1: n=2 from 1 batch, WSM M2: n=3 from 1 batch, WSM S2: n=2 from 1 batch, WSM S5: n=2 from 1 batch, WSM S5 W-AAV3: n=2 from 1 batch, WSM S5 W-AAV6: n=2 from 1 batch). Scale = 50µm.   Quantification of the staining presented in E. The boxplot represents the 1st and 3rd quartile, with its whiskers showing the minimum and maximum points and a central band representing the median. Statistical significance was determined using one-way ANOVA with Tukey's multiple comparisons test (WSM F1: n=2 from 1 batch, WSM M2: n=3 from 1 batch, WSM S2: n=2 from 1 batch, WSM S5: n=2 from 1 batch, WSM S5 W-AAV3: n=2 from 1 batch, WSM S5 W-AAV6: n=2 from 1 batch).
