Plant cell suspension cultures and transgenic plants have previously been used for the production of pharmaceutically compounds. Plant cell suspension cultures provide relatively homogenous populations of cells. These culture systems show a potential source of valuable medicinal compounds and food additives, in which some of them can not be produced by microbial cells or chemical synthesis. In this review, the authors introduce some the results on production of pharmaceutical compounds in laboratory scale from cell cultures of zedoary (Curcuma zedoaria Roscoe), centella (Centella asiatica Urban) and Solanum hainanense Hance such as curcumin, asiaticoside and solasodine, respectively. Plant-based vaccines (also called edible vaccines) for use in humans and animals are derived from the production of antigens in transgenic plants. The transgenic plants themselves, and purified proteins produced in transgenic plants, may be given as vaccines by oral administration. Oral vaccines produced in transgenic plants have several advantages, including low cost of production, safety from contamination by animal pathogens, ease of transport and storage, and no risk of needle-associated injury or disease spread. the laboratory successfully expressed antigen proteins such as CTB (cholera toxin B sububnit from Vibrio cholerae) in sugarcane (Saccharum officinarum L.) and tomato (Lycopersicon esculentum L.), or LTB (E. coli heat-labile enterotoxin B subunit) in tomato, centella, watercress (Nasturtium officinale L.) and Peperomia pellucida Kunth. Some transgenic plants (tomato and watercress) were cultivated under in vivo conditions to evaluate their growth and heterologous protein expression levels. Generally, these transgenics normally grew compare with the wild-type and strongly expressed LTB and CTB proteins.
