Growth properties of primary cell cultures

Primary cell isolate	Culture identity	Growth property
MMi3	MMi3	Primary cell culture
	MMi4	Grown for eighteen passages
MMi6	MMi6	Primary cell culture
	MMi7	Grown for seven passages
MMi17	MMi17	Adhered disassociated cells
	MMi18	Papillary groups
MMi8	MMi8	Primary cell culture
	MMi9	Seeded the following day
MMi15	MMi15	Papillary groups
	MMi16	Adhered disassociated cells

Primary cells were cultured for several passages, divided into adherent cells and papillary groups or seeded on the following day. MMi6 and MMi17 are two effusions from the same patient.
