Summary
The biopharmaceutical industry faces the challenge of reducing costs while also adopting animal-component–free cell-culture
systems. We have observed that although chemically defined cell culture media can be applied to biomanufacturing processes,
they are expensive and often do not provide optimal performance compared to standard media supplemented with sera. This article
shows that full strength or diluted CDM supplemented with plant-derived protein hydrolysates or recombinant proteins such
as rHSA provide cost-effective alternatives that can significantly enhance the production titers of the protein of interest.
Supplements also can work synergistically to further enhance cell-culture performance.
In addition to the beneficial performance results shown here for CHO and SP2/0 cell lines, other examples have been reported
in the literature for CHO,8,10–14 SP2/0,16 and many other animal host cell lines used in biomanufacturing, including BHK,21,22,24,30,31 VERO, 23,24,26,27,29 HEK,33–35 MRC,32 NS0, CEF, insect lines like Sf9 and High Five,36–40 and plant cells.42–45 These examples show the broad applicability of the approach outlined in this article.
By providing the benefits of enhanced cell density and cell viability, underscored by significant target protein production,
plant-derived hydrolysates can be used as valuable and practical tools to improve cell culture performance. The inclusion
of such supplements has become more and more popular during the development and optimization of upstream processes. Today,
6 out of 10 biopharmaceutical manufacturers have indicated they are actively using protein hydrolysate supplements.9
