Atorvastatin calcium tablets (Pfizer Pharmaceuticals Ltd., Lot No. S56741), IL-2 (Lot No. R20210328), IL-6 (Lot No. R20210328), TNF-α (Lot No. R20210328), creatine kinase isozyme cardiac type (CK-MB) (Lot No. R20210327), and cardiac troponin I (cTnI) (Lot No. R20210327) kits were purchased from the Nanjing Jiancheng Institute of Biological Engineering. Sodium pentobarbital (2%), lidocaine, sodium chloride (0.9%), sodium penicillin, methoxyamine HCl, fatty acid methyl ester (C7-C30, FAMEs) standards, pyridine, and anhydrous sodium sulfate were obtained from Sigma-Aldrich (St. Louis, MO, USA). MSTFA (N-methyl-N-(trimethylsilyl)trifluoroacetamide) with 1% (vol/vol) trimethylchlorosilane (MSTFA, with 1% TMCS), methanol (Optima LC-MS), acetonitrile (Optima LC-MS), hexane, dichloromethane, chloroform, and acetone were purchased from Thermo-Fisher Scientific (FairLawn, NJ, USA). Ultrapure water was produced by a Mill-Q Reference system equipped with an LC-MS Pak filter (Millipore, Billerica, MA).

Isolation and Characterization of Equine MSCs

Check if the same lab product or an alternative is used in the 5 most similar protocols
MSCs were collected and assessed via routine processing techniques20 (link) using bone marrow aspirate collected from the sternum of the same four donor horses as the DTS material. Cells were cultured at 37°C, 5% CO2 and 90% humidity in standard MSC media: low-glucose GlutaMAX DMEM with 110μg/mL sodium pyruvate (Gibco, USA) plus 10% MSC FBS (Gibco, USA) and 100U/mL sodium penicillin, 100μg/mL streptomycin sulfate (Sigma, USA). Cells were expanded in monolayer culture to 80% confluence and passaged twice. Flow cytometry was conducted on these four separate cell lines with a BD FACSCalibur using monoclonal antibodies previously validated in our laboratory (data not shown). The results demonstrated that approximately 90% of cells were positive for CD-90 and CD-44, common MSC surface antigens, as well as Oct-4, which is indicative of a naïve stemness found in both embryonic21 (link) and adult22 stem cell populations.

All cell lines were routinely cultured in a humidified incubator at 37°C under 5% CO2 in the indicated culture medium containing 10% fetal bovine serum (FBS, Sigma Aldrich) supplemented with 100 U/ml penicillin sodium and 100 μg/ml streptomycin sulfate (Sigma Aldrich).
HEK293T, HeLa (ATCC, American Type Culture Collection), and DAOY cells (kind gift from Dr. Maike Glitsch, Department of Physiology, Anatomy and Genetics, University of Oxford, UK) were grown in Dulbecco's modified Eagle's medium (DMEM, Gibco/Invitrogen), while PC3 cells (kindly provided by Dr. Richard Bryant from Ludwig Institute for Cancer Research, University of Oxford, UK) were maintained in RPMI 1640 (Lonza). Ptch1+/+, Ptch1+/−, and Ptch1−/− mouse embryonic fibroblasts (MEFs, kind gift from Dr. Philip Beachy, Department of Biochemistry, Stanford University), Sufu−/− MEFs (kindly provided by Dr. Stephan Teglund, Department of Biosciences and Nutrition, Karolinska Institutet, Sweden), and NIH3T3 cells (ATCC) were cultured in DMEM supplemented with 1 mM sodium pyruvate (Sigma Aldrich) and 0.1 mM MEM nonessential amino acids (Sigma Aldrich).

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.
