*IMPORTANT - DO NOT ALLOW CULTURES TO BECOME CONFLUENT.

*IMPORTANT - DO NOT ALLOW CULTURES TO BECOME CONFLUENT. Cultures must not be allowed to become confluent as this will deplete the myoblastic population in the culture.

*Cultures must not be allowed to become confluent as this will deplete the myoblastic population in the culture.

*Split cells normally 1/10 or 1/20 into 10% FBS in DMEM with 1x PSG (see [[ Splitting Cells ]])

*~~Remove and discard culture medium.~~

*Try to split at 70-80% confluence. Healthy growing cells will reach confluence every other day after a 2X dilution. Split them as fibroblasts into the final format (12 well plate, 6 well plate etc.)

*Briefly rinse the cell layer with ~~0.25%~~ (~~w/v~~) ~~Trypsin- 0.53 mM EDTA solution to remove all traces of serum which contains trypsin inhibitor.~~

*Cells normally need to be split every other day and we maintain them in 100 mm dishes, if they are not ready to split, refeed them on the second day.

*~~Add 2.0~~ to 3.~~0 ml of Trypsin-EDTA solution to flask and observe~~ cells ~~under an inverted microscope until cell layer is dispersed~~ (~~usually within 5 to 15 minutes~~).

*~~Note: To avoid clumping do not agitate the cells by hitting or shaking the flask while waiting for the cells to detach.~~ Cells ~~that are difficult~~ to ~~detach may~~ be ~~placed at 37°C~~ to ~~facilitate dispersal.~~

*Add 6.0 to 8.0 ml of complete growth medium and aspirate cells by gently pipetting.

*Add appropriate aliquots of the ~~cell suspension to new culture vessels.~~

*Inoculate at a cell concentration between 1.5 X 10 exp5 and 1.0 X 10 exp6 viable cells/75 cm2.

*Incubate cultures at 37°C.

==Differentiation==

*When cells reach 80-90% confluence switch to media (DMEM, 1x PSG with 2% horse serum).

*Replenish with fresh horse serum media media every other day.

*Cells should be fully differentiated into myotubes by day 7.

*Myotube formation is stimulated when the medium is supplemented with 2% horse serum instead of fetal bovine serum.
