In this context, cultures of primary human myotubes offer excellent material for performing studies under standardized conditions.

Diabetic myotubes expressed a reduced basal glucose uptake compared with control cultures when precultured at equal low - insulin concentrations, and the increase in fractional velocity of GS was reduced after acute insulin stimulation at identical glucose uptake rates in diabetic cultures precultured at low insulin concentrations.
