Shape of a myocyte
WebbTo maintain rod-shaped morphology, we culture the myocytes in slightly acidic culture medium, pH approx 7.0. The myocyte culture medium base is MEM with HBSS, which contains 0.35 g/L of sodium bicarbonate. Normally, this medium is used in a 1% CO 2 incubator where the medium pH is 7.4, but when placed in a 2% CO 2 incubator, the … Webb1 juni 2014 · On moderate gels, myocytes with moderate aspect ratios (∼7:1) generated the most peak systolic work compared with other cell shapes. However, on stiffer gels, low aspect ratios (∼2:1) generated the most peak systolic work.
