Did you try collagenase instead? There should be a lot of connective
tissue that trypsin hardly will be able to dissociate.

skeletal muscle cells are said not to divide at all in adults. There
should be suitable growth factors that could stimulate these cells to
divide. (Try pubmed)

probably the latter or collagenase alone

Incubate your cells with bromodeoxyuridine and stain the fixed cells
with the antibody/peroxidase conjugate. Boehringer / Roche offers a
pretty good kit for this purpose.
Some days ago, somebody posted here a method using a stain for the
plasma membrane that is diluted by division. measured with a FACS
