<h3>How to do cell culture?</h3>
To obtain a cell culture, it is necessary to disaggregate the original tissue, which can be by mechanical force or enzymatic process. These cells are grown in an adherent layer in a single layer (monolayer) or in organoid format (3D culture) or in suspension.
With this information we can conclude that rhythm Salsa resulted from the development of a muscle cell culture technique.
