Check if the same lab product or an alternative is used in the 5 most similar protocols
Fetal liver cells were immunostained with two separate panels (see Supplementary Table 15 for antibody details). Cells were stained for 30 minutes on ice followed by DAPI staining. FACS was performed on a BD FACSAria™ Fusion instrument, and data analysed using FlowJo (v10.4.1). Cells were isolated into chilled FACS tubes coated with FBS and prefilled with 500μL sterile PBS for cytospin (500 – 2000 cells), or into 1.5mL microfuge tubes containing 20μL lysis buffer (100 cells). Giemsa staining (Sigma-Aldrich) was used to determine the morphology of sorted cells on cytospins. Slides were viewed using a Zeiss AxioImager microscope, images taken of 4 fields from n = 3 samples using the 100x objective, and viewed using Zen (v2.3). Raw images supplied in Supplementary Images.

Check if the same lab product or an alternative is used in the 5 most similar protocols
Single-cell suspensions were obtained by mincing spleens with a scalpel and then by mashing them through a 100 μm nylon cell strainer (BD Falcon). Red blood cells were lysed with hypotonic ammonium-chloride-potassium (ACK) lysis buffer. The mouse CD8+ T cell-enrichment kit (Miltenyi Biotech) was used for CD8 T cell-isolation. Memory OT-I T cells were generated by transferring low numbers of naive OT-I T cells into CD45.1 congenic host mice and by infecting the hosts with 1000 CFU of Lm-N4. Memory cells were re-isolated via staining and positive selection of live cells in 2% FCS RPMI medium (Sigma Aldrich). First, cells were stained with fluorescein isothiocyanate (FITC)-KLRG1, or phycoerythrin (PE)-CD127, and biotin-conjugated CD45.2 antibodies, and then enriched via MACS separation using anti-biotin MicroBeads (Miltenyi Biotech), in accordance with the manufacturer’s instructions. Afterward, cells were sorted for KLRG1+ or CD127+ populations using a FACS Aria Fusion instrument (BD) and then transferred into new CD45.1/1-congenic C57BL/6J host mice.

siRNA-TSHZ2 (ON-TARGETplus; Dharmacon) or siRNA-CTRL (ON-TARGETplus Non-targeting; Dharmacon) was transfected into cells using the Dharmafect-1 reagent. pCMV-MYC-TSHZ2 and pDsRed-TSHZ2 were gifts from K. Kasai (Aichi Medical University School of Medicine). pEGFP-PRC1 was a gift from K. Hui (National Cancer Centre, Singapore). pEGFP-KIF4A was a gift from K. Samejima (University of Edinburgh). pEGFP-ACTN1 (#11908) and pSpCas9(BB)-2A-Puro (PX459) V2.0 (#62988) were from Addgene. Transient transfections were performed using Lipofectamine 2000 Reagent (Thermo Fisher Scientific), or jetPEI (Polyplus-transfection). The lentiviral vector pLV[Tet]-EGFP-TRE3G>hTSHZ2 (Vector-Builder, ID: VB180711-1040ara) was used for inducible overexpression of TSHZ2 (iTSHZ2), and the pHIV-Luc-ZsGreen (Addgene, #39196) was used to generate GFP-labeled cells. Viral particles encoding iTSHZ2, ZsGreen plasmid, or shRNAs targeting TSHZ2 (Sigma-Aldrich) were produced in HEK293T cells using the vectors psPAX2 (Addgene, #12260) and pMD2.G (Addgene #12259). HCC70, MDA-MB-231, and 4T1 cells were infected and selected under puromycin (2 μg/ml) or sorted using FACSAria Fusion instrument (BD Bioscience). Inducible overexpression experiments used doxycycline (2 μg/ml). For stable overexpression of TSHZ2, we used pDsRed-TSHZ2 (Takara, #632466), along with Amaxa Cell Line Nucleofector Kit V (Lonza).

Cryopreserved PBMCs from 1 of the 27 individuals (patient 107) were thawed and cultured in RPMI 1640 supplemental with 2 mM Glutamax (both from Gibco), 10% human serum (MilliporeSigma), and 100 U/ml penicillin and 100 μg/ml streptomycin (Thermo Fisher) (complete RPMI), with 50 μg/ml natural Ara h 1 (Indoor Biotechnologies), at a density of 6 × 106 cells in 1 ml medium per well in 24-well plates. Complete RPMI + 10 U/mL IL-2 (R&D Systems) was added after 5 days, and cells were cultured for a total of 14 days to expand Ara h 1–specific CD4+ T cells. After harvesting, memory CD4+ T cells were isolated with the EasySep human memory CD4+ T cell enrichment kit (Stemcell Technologies) and labeled with APC-conjugated Ara h 1 (DRB1*03:01, amino acid 415–425) tetramer (32 (link)) (made in-house), at a concentration of 10 nM for 1 hour at room temperature. After washing off excess tetramer, the cells were labeled with BUV395-conjugated anti-CD3 (clone UCHT1; BD Biosciences), APC-Cy7–conjugated anti-CD4, FITC-conjugated anti-CD45RA, and Live/Dead Fixable Blue stain (L23105; Thermo Fisher) for 30 minutes at 4°C. Live CD3+CD4+CD45RA tetramer+ and tetramer T cells were sorted with a FACSAria Fusion instrument (BD Biosciences), and genomic DNA was isolated using the AllPrep DNA/RNA Micro Kit.

We used the scRNA-seq data to identify cell surface markers that are differentially expressed between co-existing clones, in order to physically separate them via flow cytometry. For fluorescence-activated cell sorting (FACS), cells were incubated for 30 min on ice with antibodies at dilutions determined by titration experiments. Antibodies used in this study include: anti-human CD13 (ANPEP) PeCy7 (clone WM15; BioLegend) 1:10, anti-human CD184 (CXCR4) BV421 (clone 12G, BioLegend) 1:10, anti-human TM4SF4 APC (R&D) 1:10, anti-human ITM2C (clone 2E8G11, Proteintech) 1:10. For the detection of the unconjugated anti-human ITM2C antibody cells were subsequently washed and stained for 30 min on ice with anti-mouse IgG2A FITC (Biolegend) 1:100. Corresponding isotype immunoglobulin served as controls. Flow cytometric sorting was performed using a FACSAriaFusion instrument (BD Biosciences, San Jose, CA, USA) and analyses were performed using the FlowJo software (Tree Star, Ashland, OR, USA).

Developing kidney organoids on day 14 of differentiation were cultured in EGM or REGM media for 4 additional days. In order to assess mitochondrial mass, organoids were stained with MitoTracker Green FM (100 nM), a mitochondrial specific fluorescent dye at 37°C for 30 min. After incubation, kidney organoids were washed twice with PBS and disaggregated into single cell suspension using AccumaxTM for 10 minutes followed by Trypsin-EDTA 0.25% (ThermoFisher) incubation for at least 10 minutes at 37°C. Once cells dissociated, FACS buffer (PBS supplemented with 5% of FBS) was added to cease the trypsin activity and samples were centrifuged for 5 minutes at 1800 rpm. After removing the supernatant, the pellet was resuspended in 300 μl of FACS buffer and the suspension was filtered into FACS tubes. Nuclei were stained with DAPI (ThermoFisher). Cells were counted using FACS Aria Fusion Instrument (BD Biosciences). FlowJo software version 10 was used for data analysis.

Cardiac tissues were thawed on ice and cut into small pieces. Minced tissue was pre-digested with a 5-ml enzyme solution of collagenase (2500 U, Thermo Fisher Scientific) in HBSS + /+ (Gibco) for 10 min at 37 °C in a water bath. After centrifugation at 500 g and 4 °C for 5 min, the supernatant was discarded, and nuclei were isolated after cell disruption with a glass dounce homogenizer (five strokes with a loose pestle and ten strokes with a tight pestle). After filtering (20-µm strainer, pluriSelect), the suspension was centrifuged at 1000 g and 4 °C for 6 min and resuspended in 500 µl staining buffer containing 1% BSA (Sigma-Aldrich), 5 nM MgCl2 (Sigma-Aldrich), 1 mM EDTA (Gibco), 1 mM EGTA (Gibco), 0.2 U µl−1 RNasin Plus Inhibitor (Promega) and 0.1 µg ml−1 Hoechst (Life Technologies) in Dulbecco´s phosphate buffered saline (DPBS). Hoechst-positive nuclei were separated from cell debris by using the FACSAria Fusion instrument (BD Biosciences) and sorted into a staining buffer without Hoechst at 4 °C.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
