The vast majority of cell lines, attachment-dependent or suspension, grow well in a FiberCell hollow fibre bioreactor and after inoculation will expand to a density of around 10^8 cells per ml, usually within a week or ten days. Coating of fibres with a protein matrix can assist attachment and proliferating cells may grow in 3D layers or occasionally as nodules. Primary MSCs may not proliferate but can be maintained for many weeks without differentiation. Primary MSCs can produce high purity EVs continuously, separated from recirculating FBS-containing media by the fibre molecular weight cut-off. Most cell lines do not require serum once growing at high density, see: CDM-HD serum replacement.
