摘要:
Plant cells express a target protein, a production method thereof, and a method of producing a target protein using the same are disclosed. The plant cells have introduced therein a recombinant vector containing gene(s) encoding a target protein, and the plant cells include plant cambial meristematic cells (CMC) or callus. The cambial meristematic cells (CMCs) are a cell line containing innately undifferentiated cells isolated from a plant, wherein the cell line is a cell line isolated from the cambial tissue of the plant and has meristematic continuity without going through dedifferentiation into callus. A system of expressing a target protein using the recombinant plant cells according to the present invention can overcome the problems of conventional plant cell culture. In addition, it shows significantly high transformation efficiency, and thus can produce large amounts of target proteins, including biopharmaceutical proteins.

This invention is a method of minimizing the variation of cell growth and production through homogeneous cell line development. To be more specific, it is the method of isolating and proliferating single cell clone from cambium to promote the stability of the plant-derived biologically active substances production by solving the problems of decrease in cell growth and the productivity during the long term culture.

The present invention relates to a composition for enhancing immunity, comprising one or more of the following: a homogenous cell line, and a lysate, an extract and a culture medium thereof as an active ingredient. The homogenous cell line, the lysate, the extract and the culture thereof according to the present invention, which are derived from a natural product, minimize adverse side effects of prior immune enhancing agents and safe for the human body. Further, they effectively increase the activity of NK cells responsible for innate immunity, as well as increase the proliferation rate of lymph node cells when the cells were re-exposed to an antigen in a specific immune reaction to enhance acquired immunity, and thus are useful as an immune enhancing agent. In particular, the homogenous cell line, the lysate, the extract, and the culture thereof according to the present invention also effectively increase the number of hone marrow cells, thus are not only used as an adjuvant in an immune reaction, but also used in the prevention and treatment of anemia through hematopoiesis.

The present invention relates to a cell line derived from the cambium of an herbaceous plant having a storage root and a method for isolating the same. More specifically, relates to a cambium-derived homogeneous cell line having the ability to divide, which is obtained from the cambium-containing storage tissue of an herbaceous plant having a storage root without a separate dedifferentiation process, and to a method for isolating the same. The cell line derived from the cambium of an herbaceous plant having a storage root has active division ability and is homogeneous. Also, it is stable during culture, because it has not undergone a dedifferentiation process. Thus, through the optimization of proliferation thereof, the cell line can be allowed to proliferate in a large amount within a short time. Accordingly, the cell line derived from the cambium of an herbaceous plant having a storage root makes it possible to produce large amounts of useful plants which are difficult to cultivate outdoor due to various problems associated with the period of cultivation, the selection of cultivation land, cultivation cost and the like.
