Figure Lengend Snippet: a. Imaging of Aldh1l1-GFP astrocytes at P28 from the Sox9-cKO and Nfia-cKO; quantification via Scholl analysis was derived from n = 3 pairs of animals (Nfia control: OB 56, CX 52, Nfia cKO: OB 60, CX 48, Sox9 control: OB 29, CX 35, Sox9 cKO: OB 39, CX 33 cells; GLME model with Sidak’s multiple comparisons test, *P = 0.015, P = 0.41, 0.60, **P = 0.0097). b. Immunostaining for LHX2 in P28 astrocytes quantified from n = 3 pairs of animals (LME model, ****P = 1.31e-12). c. Immunostaining for NPAS3 in P28 astrocytes quantified from n = 3 pairs of animals (GLME model, **P = 0.0013). d-g. Imaging of virally labeled astrocytes lacking Lhx2 from P28 cortex; quantification via Scholl analysis was derived from n = 3 pairs of animals (41,41 cells; f, GLME model with Sidak’s multiple comparisons test, ****P = 1.29e-24; g, GLME model, ***P = 0.00099, ****P = 3.98e-05). Scale bars, 30 μm (a, e), 20 μm (b, c). Data represent mean ± s.d. (a, f), median, minimum value, maximum value and IQR (b, c, g,).
