Abstract

Over the last decades, plant-based expression systems have emerged as a novel platform for the production of recombinant proteins due to a number of advantages compared to the conventional established expression systems based on bacteria, yeast, or mammalian cell cultures. These advantages include low cost, high scalability, considerable productivity, rapid production, safety, capacity to produce multimeric or glycosylated proteins, and for certain biopharmaceuticals the option of distribution at ambient temperature and needle-free oral administration. Several molecular pharming products have reached the market-ready stage, but the number of success stories has been limited by industrial inertia driven by regulatory hurdles that create barriers to translation. This chapter discusses the advantages and opportunities offered by the use of plant-based expression systems for biopharmaceutical production. The plant-based systems appear as a meaningful alternative during global economic and ecological crisis, especially important in developing countries. The high cost of therapeutics produced by existing methods promotes consideration of the challenges and potential future directions to enable the broader application of production platforms based on plants.
