Human Skeletal Muscle Cells (SkMC)

Lot specific orders are not able to be placed through the web. Contact your local sales rep for more details.

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) and are provided in a cryopreserved format. 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.

Rigid quality control tests are performed for each lot of Human Skeletal Muscle Cells. They are tested for cell morphology, adherence rate, and cell viability. Immunohistochemical tests for cell-type specific markers are carried out for each lot. Growth performance is tested through multiple passages up to 15 population doublings (PD) under culture conditions without antibiotics and antimycotics. Furthermore, the capacity to differentiate into multinucleated syncytia is routinely checked for each lot. 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).

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.
