Cell Harvesting: is a step in the production of therapeutics like insulin that are grown in bacteria or antibodies produced in mammalian cell culture. Harvesting cells from an organism, starts with a biopsy that can be performed by needle aspiration, scalpel, punch biopsy or laser. In the case of cell therapy, the harvested cells are the treatment but they may first be cultured and then harvested from cell culture before being administered to patient. In addition to the biomedical field, cell harvesting is a key step in bioprocessing of products like meat.
