Human skeletal muscle cells culture?

Dear Dr. Wolfgang,

In fact, in skeletal muscle from adult, there are some cells called satelite
cell who can divide something like precursor cell. I have beening culturing
some dishs of adult skeletal muscle cell. But several times, I failed to
culture others. The protocol is just the same. The only difference is the
skeletal muscle tissues come from different patients who undergo operations
of fracture. Any suggestion?

Best regards,

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
