Application

Primary Human Skeletal Muscle Cells (SkMC) are isolated from different skeletal muscles (e.g. Musculus pectoralis major) from adult single donors (lot specific source information is available on request). They are positive for sarcomeric myosin and negative for smooth muscle specific α-actin.New skeletal muscle cells originate from quiescent satellite cells, which are located in the muscle fibers between the basal lamina and the sarcolemma. Quiescent satellite cells are activated by stimuli such as muscle damage. After activation, the cells, now called myoblasts, start to proliferate and fuse with damaged muscle fibers or with one another forming new myotubes.SkMC are optimal for in vitro muscle studies. They proliferate very well in the mitogen-rich PromoCell Skeletal Muscle Cell Growth Medium. Fusion to myotubes with typical multinucleated syncytia can be induced by using the PromoCell Skeletal Muscle Cell Differentiation Medium.

Other Notes

The Cell Pellets can be stored indefinitely at -20°C, and for up to 1 month at 4°C. Note: The Cell Pellets will not freeze at -20°C. Always centrifuge product briefly before opening vial.

Physical form

Pellet is dissolved in RNAlater^® for downstream analysis of DNA, RNA or protein profiles. Cells are not revivable.

Quality

Rigid quality control tests are performed for each lot of the corresponding cells. They are tested for cell viability, cell morphology, growth performance and for cell-type specific markers. In addition, all cells have been tested for the absence of HIV-1, HIV-2, HBV, HCV, HTLV-1, HTLV-2 and microbial contaminants (fungi, bacteria, and mycoplasma).

Warning

Although tested negative for HIV-1, HIV-2, HBV, HCV, HTLV-1 and HTLV-2, the cells – like all products of human origin – should be handled as potentially infectious. No test procedure can completely guarantee the absence of infectious agents.
