Extended Data Fig. 6

a, Proportion of CTB-labeled cells from GLUT and IF that are labeled with Cdh8 and Sema3e. The GLUT has a significantly larger proportion of Cdh8 + and Sema3e + cells than the IF. n = 5 biologically independent animals. b, Lower power view of in situ hybridization against Prkcd/Sv2a, and Kcnq5/Chodl (insets=Fig. 4h) in longitudinal sections demonstrates the specificity of CTB injections into the Soleus (SOL) and Tibialis anterior (TA). n = 5 (TA) and 4 (SOL) biologically independent animals. One-way ANOVA with post-hoc Sidak multiple comparison test between same-gene conditions. Adjusted p-values=0.0212 (Cdh8) and 0.0499 (Sema3e). c, Expression of FF and SF gene modules overlaid on UMAP of all α motor neurons. d, Average log-normalized canonical marker expression of Chodl (fast-firing) and Sv2a (slow-firing). Scale bars = 250 µm. e, Proportion of Prkcd + cells positive for Sv2a (left) and proportion of Chodl + cells that are positive for Kcnq5 (right). n = 3 biologically independent animals. f, Representative in situ hybridization showing Kcnq5 is expressed in a subset of Chodl + cells. n = 4 biologically independent animals. Scale bar=50 µm inset and 200 µm overview. *=p value<0.05, **=p value <0.01, ***=p value<0.001, ****=p value<0.0001. Error bars are SEM.
