extract_protocol:
Cardiomyocytes were isolated using Langendorff perfusion from the left ventricle as previously described. Enzymatic dissociation using Langendorff perfusion was performed with 35 mL enzyme solution (type 2 collagenase 1 mg/mL [Worthington], protease type XIV 0.05 mg/mL [Sigma-Aldrich], NaCl 130 mM, KCl 5.4 mM, MgCl2 0.5 mM, NaH2PO4 0.33 mM, D-glucose 22 mM, HEPES 25 mM; pH 7.4) pre-heated to 37 °C, at a rate of 3 mL/min. To neutralize enzymatic activity, fetal bovine serum (FBS) was added to the solution to a final concentration of 0.2% (v/v). After perfusion of digestion buffer, left ventricle was cut according to each sectional region (IR, RR) and cardiomyocytes were subsequently isolated. Cell suspensions were filtered through a 100-μm nylon mesh cell strainer and centrifuged at 100 g for 2 min, after which the supernatant was discarded. To prevent hypercontraction, the cardiomyocytes were resuspended in medium (NaCl 130 mM, KCl 5.4 mM, MgCl2 0.5 mM, NaH2PO4 0.33 mM, D-glucose 22 mM, HEPES 25 mM, FBS 0.2%; pH 7.4) containing a low concentration of calcium (0.1 mM). Rod-shaped live cardiomyocytes (viability of cardiomyocytes was ≥80% for all time points) were collected immediately with a 0.2–2-µL pipette (sample volume, 0.5 µL) and incubated in lysis buffer.
Single-cardiomyocyte cDNA libraries were generated using the Smart-seq2 protocol26 and the efﬁciency of reverse transcription was assessed by examining the cycle threshold (Ct) values of control genes (Tnnt2) from quantitative real-time polymerase chain reaction (qRT-PCR) using a CFX96 Real-Time PCR Detection System (Bio-Rad), and the distribution of cDNA fragment lengths was assessed using LabChip GX (Perkin Elmer) and/or TapeStation 2200 (Agilent Technologies). The following primer sets were used for qRT-PCR: Tnnt2 mRNA forward: TCCTGGCAGA GAGGAGGAAG; Tnnt2 mRNA reverse: TGCAGGTCGA ACTTCTCAGC. A Ct value of 25 was set as the threshold. The sequencing libraries were subjected to paired-end 51-bp RNA sequencing on a HiSeq 2614 (Illumina) in rapid mode

value: The clean reads were aligned to the mouse genome (mm10) using STAR (version 2.7.122a)

extract_protocol:
On the day of bariatric surgery, approximately 2-3g each of subcutaneous abdominal (SAT) and omental visceral adipose (VAT) tissue was harvested intraoperatively and immediately processed. Tissue was subject to collagenase digestion for separation of mature adipocytes (MA) and SVC, and for differentiation of preadipocytes as previously described in PMID: 28836202 with details in supplemental methods. SVC from SAT and VAT was left untreated or infected with SARS-CoV-2 as described above. After 24hpi, cells were collected, washed, and diluted at a density of 1x103 cells per µl in cold DMEM (Life technologies; 11885-092) media supplemented with 10% FBS (Corning, MT35016CV).
The gel beads-in-emulsion (GEM) single cell 3’ kit v3.1 dual index kit (10X Genomics) was used following manufacturer’s recommendations with slight modifications. Briefly, SVC from SAT and VAT was left untreated or infected with SARS-CoV-2 as described above. After 24hpi, cells were collected, washed, and diluted at a density of 1x103 cells per µl in cold DMEM (Life technologies; 11885-092) media supplemented with 10% FBS (Corning, MT35016CV). 10,000 cells per lane were loaded onto a Chromium Controller in the BSC per manufacturer’s instructions. Following GEM creation, samples were transferred into PCR tube strips prior to transferring into a PTC-200 thermocycler (MJ Research) for RT. The RT parameters were the following: 45 minutes at 53oC, followed by 5 minutes at 85oC, then 15 minutes at 60oC and finally samples were kept at 4oC. Barcoded cDNA was removed to BSL2 and sequencing libraries were prepared per manufacturer's recommendation, with a TapeStation 4200 (Agilent) used for quality control. Libraries were pooled for a final concentration of 10nM and sequenced on a NovaSeq S2 (Ilumina) at the Chan Zuckerberg Biohub (San Francisco).

After perfusion of digestion buffer, left ventricle was cut according to each sectional region (IR, RR) and cardiomyocytes were subsequently isolated. Cell suspensions were filtered through a 100-μm nylon mesh cell strainer and centrifuged at 100 g for 2 min, after which the supernatant was discarded. To prevent hypercontraction, the cardiomyocytes were resuspended in medium (NaCl 130 mM, KCl 5.4 mM, MgCl2 0.5 mM, NaH2PO4 0.33 mM, D-glucose 22 mM, HEPES 25 mM, FBS 0.2%; pH 7.4) containing a low concentration of calcium (0.1 mM). Rod-shaped live cardiomyocytes (viability of cardiomyocytes was ≥80% for all time points) were collected immediately with a 0.2–2-µL pipette (sample volume, 0.5 µL) and incubated in lysis buffer.
Single-cardiomyocyte cDNA libraries were generated using the Smart-seq2 protocol26 and the efﬁciency of reverse transcription was assessed by examining the cycle threshold (Ct) values of control genes (Tnnt2) from quantitative real-time polymerase chain reaction (qRT-PCR) using a CFX96 Real-Time PCR Detection System (Bio-Rad), and the distribution of cDNA fragment lengths was assessed using LabChip GX (Perkin Elmer) and/or TapeStation 2200 (Agilent Technologies). The following primer sets were used for qRT-PCR: Tnnt2 mRNA forward: TCCTGGCAGA GAGGAGGAAG; Tnnt2 mRNA reverse: TGCAGGTCGA ACTTCTCAGC. A Ct value of 25 was set as the threshold. The sequencing libraries were subjected to paired-end 51-bp RNA sequencing on a HiSeq 2606 (Illumina) in rapid mode

value: The clean reads were aligned to the mouse genome (mm10) using STAR (version 2.7.114a)

On the day of bariatric surgery, approximately 2-3g each of subcutaneous abdominal (SAT) and omental visceral adipose (VAT) tissue was harvested intraoperatively and immediately processed. Tissue was subject to collagenase digestion for separation of mature adipocytes (MA) and SVC, and for differentiation of preadipocytes as previously described in PMID: 28836202 with details in supplemental methods. SVC from SAT and VAT was left untreated or infected with SARS-CoV-2 as described above. After 24hpi, cells were collected, washed, and diluted at a density of 1x103 cells per µl in cold DMEM (Life technologies; 11885-092) media supplemented with 10% FBS (Corning, MT35016CV).
The gel beads-in-emulsion (GEM) single cell 3’ kit v3.1 dual index kit (10X Genomics) was used following manufacturer’s recommendations with slight modifications. Briefly, SVC from SAT and VAT was left untreated or infected with SARS-CoV-2 as described above. After 24hpi, cells were collected, washed, and diluted at a density of 1x103 cells per µl in cold DMEM (Life technologies; 11885-092) media supplemented with 10% FBS (Corning, MT35016CV). 10,000 cells per lane were loaded onto a Chromium Controller in the BSC per manufacturer’s instructions. Following GEM creation, samples were transferred into PCR tube strips prior to transferring into a PTC-200 thermocycler (MJ Research) for RT. The RT parameters were the following: 45 minutes at 53oC, followed by 5 minutes at 85oC, then 15 minutes at 60oC and finally samples were kept at 4oC. Barcoded cDNA was removed to BSL2 and sequencing libraries were prepared per manufacturer's recommendation, with a TapeStation 4200 (Agilent) used for quality control. Libraries were pooled for a final concentration of 10nM and sequenced on a NovaSeq S2 (Ilumina) at the Chan Zuckerberg Biohub (San Francisco).

Cardiomyocytes were isolated using Langendorff perfusion from the left ventricle as previously described. Enzymatic dissociation using Langendorff perfusion was performed with 35 mL enzyme solution (type 2 collagenase 1 mg/mL [Worthington], protease type XIV 0.05 mg/mL [Sigma-Aldrich], NaCl 130 mM, KCl 5.4 mM, MgCl2 0.5 mM, NaH2PO4 0.33 mM, D-glucose 22 mM, HEPES 25 mM; pH 7.4) pre-heated to 37 °C, at a rate of 3 mL/min. To neutralize enzymatic activity, fetal bovine serum (FBS) was added to the solution to a final concentration of 0.2% (v/v). After perfusion of digestion buffer, left ventricle was cut according to each sectional region (IR, RR) and cardiomyocytes were subsequently isolated. Cell suspensions were filtered through a 100-μm nylon mesh cell strainer and centrifuged at 100 g for 2 min, after which the supernatant was discarded. To prevent hypercontraction, the cardiomyocytes were resuspended in medium (NaCl 130 mM, KCl 5.4 mM, MgCl2 0.5 mM, NaH2PO4 0.33 mM, D-glucose 22 mM, HEPES 25 mM, FBS 0.2%; pH 7.4) containing a low concentration of calcium (0.1 mM). Rod-shaped live cardiomyocytes (viability of cardiomyocytes was ≥80% for all time points) were collected immediately with a 0.2–2-µL pipette (sample volume, 0.5 µL) and incubated in lysis buffer.
Single-cardiomyocyte cDNA libraries were generated using the Smart-seq2 protocol26 and the efﬁciency of reverse transcription was assessed by examining the cycle threshold (Ct) values of control genes (Tnnt2) from quantitative real-time polymerase chain reaction (qRT-PCR) using a CFX96 Real-Time PCR Detection System (Bio-Rad), and the distribution of cDNA fragment lengths was assessed using LabChip GX (Perkin Elmer) and/or TapeStation 2200 (Agilent Technologies). The following primer sets were used for qRT-PCR: Tnnt2 mRNA forward: TCCTGGCAGA GAGGAGGAAG; Tnnt2 mRNA reverse: TGCAGGTCGA ACTTCTCAGC. A Ct value of 25 was set as the threshold. The sequencing libraries were subjected to paired-end 51-bp RNA sequencing on a HiSeq 2589 (Illumina) in rapid mode

value: The clean reads were aligned to the mouse genome (mm10) using STAR (version 2.7.97a)
