As a result, only two plant-made pharmaceuticals have been FDA-approved to date: a vaccine produced in the Nicotiana tabacum cell suspension culture expression system (vaccine against Newcastle disease virus in poultry) and recombinant human glucocerebrosidase produced in the Daucus carota cell suspension culture system (for Gaucher’s disease treatment) [48,49,50] as cited in Lee et al. [51]. The gene discussed is GBA1; the disease is Gaucher disease.
