(제넨텍이 제조하여 노바티스가 판매하는 Xolair는 2005년도 기준 미국 내에서만 3억2천만 달러, 2008년에는 매출이 7억5천 달러 예상 (from 메디컬뉴스)되어 시장성이 있다.)
Principles of plant cell culture
Method: hairy root cultures, shooty teratomas cultures, immobilized-cell cultures, suspension cell cultures
(the most amenable to GMP procedure and easily cultivated in large-scale bioreactor)
Plant species: Arabidopsis thaliana, Taxus cuspidata, Catharanthus roseus, Nicotiana tabacum(NT-1, BY-2), oryza sativa(Taipei309), soybean, tomato, alfalfa
The rice cell lines have been used because of the possibility that they could be more favorable than tobacco in terms of by-product levels and, since they are derived from food crops.
