| Extraction protocol |
Lizard tails were anesthetized by exposing tails to a spray of ethyl chloride for 10 seconds and amputated with a sterile scalpel blade to begin regeneration. Tail samples were collected in Hank’s balanced salt solution (HBSS) supplemented with 100 units/mL penicillin and 100 µg/mL streptomycin (HBSS with P/S). Samples were collected at 0, 1, 3, 7, 14, 21, and 28 days after initial amputation or days post-amputation (DPA) for cell dissociation. Longer tail samples (14, 21 and 28 DPA) were further split into two portions at the original amputation plane using a sterile scalpel. Three tail samples per time point were cut to 3-5 mm pieces in length and each piece was cut into 1/8ths. Tail pieces were added to gentleMACS™ C tubes (Miltenyi Biotec, PN: 130-093-237) containing 2.5 mL Dulbecco’s modified Eagle media (DMEM), 100 µL proprietary Enzyme D, 50 µL Enzyme R and 12.5 µL Enzyme A from Multi Tissue Dissociation Kit 1 (Miltenyi Biotec, PN: 130-110-201). Tubes were inverted and placed onto gentleMACS™ OctoDissociator with sleeve (Miltenyi Biotec, PN: 130-096-427) and a fibroblast dissociation protocol was run for 1 hour. Enzymatic activity was inactivated with DMEM supplemented with 10% fetal bovine serum (FBS). Cells were gently resuspended via pipetting and run through MACS® 70 µm SmartStrainer (Miltenyi Biotec, PN: 130-098-462), followed by filtration via Scienceware FlowMi® 40 µM Cell Strainers for p1000 pipettes (Sigma Aldrich, PN: H13680-0040). Cells were pelleted and washed with DMEM with 10% FBS. Cells were resuspended in HBSS with 0.04% bovine serum albumin (BSA) prior to library preparation.
Isolated cells were counted on a hemocytometer and prepared using the 10x Genomics Chromium Single-Cell Gene Expression kit (V2, PN: 120267) according to manufacturer’s recommendations. Cells were encapsulated into droplets via gel bead-in emulsion (GEM) method for barcoding using the 10x Genomics Chromium controller (PN: 1000202). GEMs were incubated for cDNA synthesis, followed by amplification and library construction, according to manufacturer’s instructions.

| Description |
10x Genomics
|
| Data processing |
Demultiplexing, barcode processing, feature counting and aggregation was performed using Cell Ranger pipeline (10x Genomics, v3.1.2)
Assembly: Green anole (A. carolinensis) genome FASTA and GTF files (v2.105) were used to generate a reference genome for indexing by Cell Ranger mkref function (v3.1.2, 10x Genomics). The reference genome FASTA and GTF files were sourced from the Ensembl database for green anole, AnoCar2.0v2 (GCA_000090745.2), ensembl release 105. (http://dec2021.archive.ensembl.org/Anolis_carolinensis/Info/Index).
