| Extraction protocol |
Bulk RNA-seq libraries were prepared using KAPA mRNA HyperPrep Kit (Roche # 08098123702) and sequenced on an Illumina NovaSeq
Testes from gray short-tailed opossums at Yale or adult (8-16 week old) male C57BL6/J mice purchased from Jackson Laboratories were harvested and dissociated into single-cell suspension for RNA isolation using collagenase and trypsin. Briefly, testes were removed from the scrotum, decapsulated from the tunica albuginea, and incubated in 0.75mg/mL collagenase in Dulbecco’s Modified Eagle Medium (Gibco 11965-09L; Thermo Fisher Scientific, Inc.) at 37oC. DMEM was added to dilute collagenase and samples were centrifuged for 5 minutes at 400 x g at room temperature. Supernatant was discarded and samples were washed in DMEM. Samples were resuspended in 0.05% trypsin-EDTA (Gibco 25300-054; Thermo Fisher Scientific Inc.) with DNAse (1:10,000; Stem Cell Technologies #07900, Vancouver BC, Canada). The reaction was quenched with 10% Cosmic Calf Serum (Sigma-Aldrich #C8056, Burlington, MA, USA) in DMEM (CCS-DMEM) and centrifuged. Samples were resuspended in CCS-DMEM and filtered through a 100-micron filter. Cell concentration was determined by hemocytometer.

| Description |
polyA RNA-seq
|
| Data processing |
Assembly: ASM229v1
RNA-seq libraries were aligned using HISAT 2.2.1 (Kim et al., 2019) with Ensembl (Yates et al., 2020) release 104 as a reference and -data output type. Output files were converted from SAM format to sorted BAM format using SAMtools-1.12 (Danecek et al., 2021; Li et al., 2009; Murat et al., 2021). Raw count values and FPKM were obtained using StringTie 2.1.4 (Pertea et al., 2016) with the -e and -G options and Ensembl (Yates et al., 2020) ASM229 release 104 or GRCM39 release 104 reference files for opossum and mouse, respectively.
Supplementary files format and content: scRNA-seq: filtered index (.tsv), feature (.tsv), and matrix (.mtx) files
Supplementary files format and content: bulk RNA-seq: tab-delimited text files with FPKM values by gene
