cell hybridization
When fusing cells in suspension or monolayer cell systems, the treatment of cells with PEG should be short to minimize cell death. Usually, a 24 h recovery peri

Electronic cell counting by means of a resistor
Digest the monolayer culture with trypsin, or take a sample from the suspension culture; prepare a coverslip and add the cells to the small chamber of the hemoc
Collagenase dissociation of tissues
Chopped tissues were placed in complete medium containing collagenase for incubation, and after the tissues were broken down, collagenase was removed by centrif
Isolation and culture of single muscle fibers from skeletal muscle
Grind whole skeletal muscle treated with collagen to disperse into single muscle fibers. Cultivate single muscle fibers on Matrigel and collect the migrating ce
Culture of chondrocytes with alginate microbeads
