LCM-seq strategy to reveal cell intrinsic mechanisms of motor neuron vulnerability and resistance in SMA. (A) We used “delta 7” mice (Smn−/−/SMN2+/+/SMNΔ7+/+) as a model for severe SMA and littermates homozygous for murine Smn as controls (Smn+/+/SMN2+/+/SMNΔ7+/+). (B) Pairwise Spearman's correlation on log10-transformed data of all samples per cell type, genotype, and age. (C) Principal component analysis on the whole gene expression data set. (P) Postnatal day; (CNS) central nervous system; (LCM-seq) laser capture microdissection coupled with RNA sequencing; (SC) spinal cord; (CN) cranial nerve; (CN12) hypoglossal nucleus; (CN10) dorsal motor nucleus of the vagus nerve; (CN7) facial nucleus; (CN3/4) oculomotor and trochlear nuclei; (RN) red nucleus; asterisks in A indicate vulnerable cell types in this mouse model; (WGCNA) weighted gene correlation network analysis; (GO) Gene Ontology.
