On the way to commercializing plant cell culture platform for biopharmaceuticals: present status and prospect

Jianfeng Xu* and Ningning Zhang

Plant cell culture is emerging as an alternative bioproduction system for recombinant pharmaceuticals. Growing plant cells in vitro under controlled environmental conditions allows for precise control over cell growth and protein production, batchto- batch product consistency and a production process aligned with current good manufacturing practices. With the recent US FDA approval and commercialization of the world’s first plant cell-based recombinant pharmaceutical for human use, β-glucocerebrosidase for treatment of Gaucher’s disease, a new era has come in which plant cell culture shows high potential to displace some established platform technologies in niche markets. This review updates the progress in plant cell culture processing technology, highlights recent commercial successes and discusses the challenges that must be overcome to make this platform commercially viable.
