Check if the same lab product or an alternative is used in the 5 most similar protocols
Preparation of limb muscle for flow cytometric analysis was adapted from Liu et al. [28 (link)]. In short, dissected tissue was minced thoroughly to small pieces in F10 medium (Lonza) containing collagenase II (750 U/ml; Fisher Scientific) using scalpels. Minced tissue was dissociated for 70 min in F10 medium containing 750 U/ml collagenase II), then for 30 min in F10 medium containing collagenase II (100 U/ml) and dispase (1.1 U/ml; Fisher Scientific). Cell suspensions were filtered over a 40 μM cell strainer (Falcon) and a small sample was retrieved to determine total mononuclear cell count using a hematocytometer. The cell suspensions were stained with CD31-APC (1:100), CD45-APC (1:100), Sca1-FITC (1:100) and Vcam-biotin (1:50) primary antibodies. Vcam was visualized using streptavidin-PECY7 (1:100). All antibodies for flowcytometry were derived from BD Biosciences. Cell viability was determined by staining with 1 μg/ml Hoechst 33258 (Sigma). Samples were analyzed on a BD-ARIAIII (BD biosciences).

Primary myoblasts were isolated from the forelimbs and hindlimbs of three or four 5-day-old littermates57 (link). The muscles were dissected and minced, disaggregated enzymatically in 4 ml PBS containing 1.5 U/mL dispase II and 1.4 U/mL collagenase D (Roche, Grenzacherstrasse, Basel, Switzerland), and triturated with a 10-ml pipette every 5 min for 20 min at 37 °C. The cells were filtered through a 70-μm mesh (BD Bioscience, San Jose, CA, USA) and centrifuged at 1000 × g for 5 min. The cell pellet was dissociated in 10 mL F10 medium (Invitrogen, Life Technologies) supplemented with 10 ng/mL basic fibroblast growth factor (PeproTech; Rocky Hill, NJ, USA) and 10% cosmic calf serum (GE Healthcare). Finally, the cells were pre-plated twice on non-collagen coated plates for 1 h to deplete fibroblasts, which generally adhere faster than myoblasts. For differentiation, the primary myoblasts obtained were cultured to 75% confluence in DMEM containing 100 U/mL penicillin, 100 μg/mL streptomycin, and 5% horse serum (Invitrogen, Life Technologies).

Check if the same lab product or an alternative is used in the 5 most similar protocols
Human dermal primary fibroblasts isolated from foreskin samples were cultured in F10 medium (Gibco, Invitrogen, Carlsbad, CA, USA) containing 10% fetal bovine serum (FBS), 0.5% penicillin and 2% glutamine.
For hypoxic conditions, fibroblasts were maintained for 24 h (for RNA analysis) or 48 h (for protein analysis) in 1% O 2 by using a Hypoxia Incubator Chamber (Stemcell Technologies, Grenoble, France).
The oxidative stress was produced by adding hydrogen peroxide
to cultured fibroblasts at different doses (0-200 mM) for the indicated times. Cell proliferation was measured by colorimetric immunoassay based on BrdU incorporation (Roche Diagnostics). Total cellular glutathione was detected after 4 h incubation by means of the GSH + GSSG/GSH Assay Kit (Abcam). Chronic hyperglycemic conditions were obtained by culturing fibroblasts for three weeks in commercially available Dulbecco's Modified Eagle's Medium (DMEM, Sigma-Aldrich) containing 25 mM or 5.5 mM D-glucose. The high glucose and low glucose DMEM had similar osmolarity.

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.
