I just read this paper about moss bioreactors and thought it had some good points. Moss can make antibodies just as well CHO cells if not better. Some moss versions are even better than CHO versions of the same antibody because they lack sugar residues that interfere with ADCC. Also, moss doesn't face the same contamination risk as mammalian cells and has inexpensive media requirement... https://www.reddit.com/r/biotech/comments/1l7hbnu/comment/n3gcogk/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button
