Backed by the same quality, service, and support that you expect from atcc. Cells that can be subcultured many times are called cell lines and examples have been isolated from diverse tissues and cell types. Except for the enzymatic andor physical dissociation required for extracting the cells from their tissue of origin, primary cells are not altered in any way. After the first subculture, the primary culture becomes known as a cell line or subclone. Primary cells versus cell lines sciencell research.

Primary culture broadly involves the culturing techniques carried following the isolation of the cells, but before the first subculture. Before discussing the difference between primary and secondary cell culture, let us first briefly define what cell culture is.
