C2C12 Myoblast Differentiation Protocol

Check if the same lab product or an alternative is used in the 5 most similar protocols
C2C12 myoblasts (ATCC) were seeded onto non-coated 6-well plates and maintained in Dulbecco’s modified Eagle’s medium (DMEM, Welgene, Korea) containing 10% fetal bovine serum (FBS), 100 U/mL penicillin, and 100 mg/mL streptomycin (Welgene, Korea) in a humidified atmosphere of 95% air and 5% CO2 at 37°C. For proliferation test, 5 mM L-carnitine or 300 uM oleic acid or a mixture (5 mM L-carnitine and 300 μM oleic acid) were added to the growth medium (10% FBS), based on previous studies15 (link),17 (link). When myoblasts were confluent (95%), the growth medium was changed to a differentiation medium (DM) supplemented with 2% horse serum (HS), 100 U/mL penicillin, and 100 mg/mL streptomycin (Welgene, Korea). DM was changed every 24 h. For the differentiation test and fusion index assay, 5 mM L-carnitine or 300 μM oleic acid or a mixture were added to DM supplemented with 2% HS and incubated for 96 h. The detailed incubation method for each experiment is described in each figure legend. Cell culture was performed a minimum of six independent times. As the fusion index is a myological indicator showing the degree of myogenic differentiation from myoblasts to myotubes, the index is calculated as the number of nuclei in myotubes divided by the total number of nuclei counted, which is expressed as a percentage. A schematic diagram of the cell culture protocol is presented in Figure 1.

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.
