Experimental details: Figure 3. Single cell analysis of skeletal muscle stem cells (MuSCs) in age shows a subset express transcripts associated with the neuromuscular junction. ( A ) Experiment design schematic. MuSCs were fluorescent activated cell sorting (FACS) enriched from young and aged wild-type (WT) mice, then analyzed by IF, single cell mRNA sequencing (scRNA-Seq), or single-molecule fluorescence in situ hybridization (smFISH). ( B ) Left: Dimensional reduction and unsupervised clustering of young (2-3 months) and aged (22-24 months) WT FACS-isolated MuSCs and limb muscle cells from 24-month Tabula Muris Senis datasets colored by sample type showing overlap between FACS-enriched MuSCs and MuSC clusters among all mono-nucleated cells. Four and five independent replicates of young and age, respectively, were sequenced where each sample is composed of a pool from two mice. Cell types were identified according to markergene expression and labeled on the plot. NMJ - neuromuscular junction; TL - tenocyte; MSC - mesenchymal stromal cell; Immune - CD45+ immune cell; Endo - endothelial cell; SMC - smooth muscle cell. Right: Plots split by sample type showing contribution to uniform manifold approximation and projection (UMAP) and re-clustered UMAP of the NMJ-associated cluster. ( C ) Stacked bar plot representing the fraction of the sorted cell populations that clustered with each mono-nucleated cell type as well as the number of Pax7+S100b- (MuSC) and Pax7+S100b+ (NMJ) cells based on IF stains.

Experimental details: Figure 5. Neurodegeneration activates muscle stem cells (MuSCs) in a similar manner to aging and rescue of motor neurons partially reverses this activation state. ( A ) Schematic of neuromuscular junction (NMJ) in young (top) and aged or Sod1 -/- (bottom) muscle, whereby NMJ becomes fragmented or partially denervated. ( B ) Representative images of Sod -/- and SynTgSod1 -/- myofibers from uninjured and sciatic nerve transection (SNT) tibialis anterior muscles stained with DAPI (blue) and alpha-bungarotoxin (orange). ( C ) Quantification of the number of subsynaptic nuclei per synaptic area in uninjured control and SNT muscle fibers from both Sod1 -/- and SynTgSod1 -/- mice, normalized to the subsynaptic nuclei per area of Sod1 -/- uninjured control (*p < 0.05, two-way ANOVA with Tukey post hoc test). ( D ) Uniform manifold approximation and projection (UMAP) dimensional reduction of fluorescent activated cell sorting (FACS)-isolated MuSCs (FSMs) from young and aged wild-type (WT) mice, 10-month Sod1 -/- mice, 10-month Sod1 -/- rescue (SynTgSod1 -/- ) mice, and public Tabula Muris Senis limb muscle datasets colored by sample type. One and two independent replicates of Sod1 -/- and Sod1 -/- rescue (SynTgSod1 -/- ) mice, respectively, were sequenced where each sample is composed of a pool from two mice. Cell types were identified according to markergene expression and labeled on the plot. TL - tenocyte; MSC - mesenchymal stromal cell; Immune - CD45+ immune cell; Endo - endotheli

Experimental details: 1 Figure Morphological and histopathological characterization of PDX and cell line models. (A) Schematic diagram outlining the strategy for the establishment of PDX and cell line models from the patient tumors. Representative images of brain MRI, tumor-derived cells, xenograft in sciatic nerve (SN, black arrow), and cell line illustrating the steps of this protocol are shown. A representative image of tumor-derived cell cluster (asterisk) that augmented the growth of the culture is shown. A representative image of positive staining for beta-galactosidase (SA-beta-Gal) in cultured cells after serial passages for 12 weeks is shown. Representative images of macroscopic tissue and IHC staining for Cyclin D1 are shown. (B) Representative images of HE staining, showing spindle-cell lesions with intermixed (Antoni A) and loose (Antoni B) cellular arrangements, Verocay bodies (blue arrow) and perivascular hyalinization (black arrow) in patient and xenograft tumors.
