The present invention relates to a serum-free or low protein concentration medium for culturing animal cells or cells derived from animal cells, and relates to a cell culture medium characterized by containing royal jelly and/or components of royal jelly. be. Animal cells and animal cell-derived fats are known to produce active substances such as antibodies, interferon, insulin, and enzymes, and it is possible to obtain these active substances by culturing these cells. being carried out or attempted. Traditionally, in order to culture these cells, it is almost always necessary to add serum to the culture medium. Fetal bovine serum, calf serum, etc. are generally used as serum, and the amount added is usually about 10%. However, these serums are expensive;
There are drawbacks such as inconsistent quality and limited supply. Furthermore, since serum contains a wide variety of components such as proteins, it is difficult to separate and purify effective substances from culture. As a result of repeated research to solve these problems, the present inventors discovered that cells can be grown in a serum-free medium with a low protein concentration, and have completed the present invention. Royal jelly is obtained from bees, etc., and can be obtained from, for example, the Queen Bee Garden Beekeeping Association, an agricultural cooperative corporation. Royal jelly has a high viscosity, so it is extracted with phosphate buffered saline, 100mM Na-Hepes buffer, water, etc., and dialyzed to reduce the viscosity (hereinafter referred to as royal jelly extraction and dialysis fraction).
Using , subsequent processing becomes easier. Molecular weight fractionation can be carried out using, for example, Sephadex G-200 (Pharmacia Fine
Chemicals) or by gel filtration using Cellulofine GC-700 (Seikagaku Corporation). The equilibration and elution solutions used at that time are:
For example, phosphate buffered saline, 100mM Na−
Hepes buffer (PH7.4), water, etc. Royal jelly protein having a molecular weight of about 58,000 (hereinafter abbreviated as royal jelly protein) is purified, for example, as follows. Royal jelly is diluted 2 times with phosphate buffered saline and then dialyzed against it. After dialysis, it is centrifuged at 20,000 x g, and the resulting supernatant is subjected to molecular weight fractionation using the method described above to obtain a fraction with a molecular weight of 50,000 to 80,000. After dialysis of this fraction against 1mM Tris-HCl buffer (PH8.0), Blue Sepharose (Pharmacia Fine
Chemicals) to obtain a flow-through fraction, that is, royal jelly protein. This royal jelly protein was analyzed by SDS electrophoresis (Weber,
K., and Osborn, M. (1969) J.Biol.Chem.244,
4406-4412), and the molecular weight determined by the same electrophoresis was 58,000. The cell culture medium of the present invention is used by adding these materials to a basal medium (not containing serum) used for normal animal cell culture. In addition, 1 of these royal jelly and/or royal jelly components, milk and/or milk components, and a fraction of placental blood with a molecular weight of 50,000 to 80,000.
It is also possible to use seeds or more by adding them to the basal medium. The milk components are obtained as follows. Milk is centrifuged at, for example, 20,000 x g to obtain a solution fraction. The resulting fractions are subjected to molecular weight fractionation in the same manner as in the case of royal jelly to obtain a fraction with a molecular weight of 200,000 or more and a fraction with a molecular weight of 40,000 to 90,000. Lactoferrin can be extracted, for example, by the method of Lo¨nnerdal et al.
nnerdal, B., Carlsson, J., and Porath, J.
(1977) FEBS Letter.75, 89-92). In addition, for the fraction of human placental blood with a molecular weight of 50,000 to 80,000 (hereinafter referred to as human placental blood fraction), for example, blood naturally exuded from the placenta is centrifuged at 20,000 x g.
The supernatant can be further obtained by molecular weight fractionation using the method described above. As the basal medium of the culture medium of the present invention, any medium can be used as long as it is used for culturing general animal cells. For example, Dulbecco's
Modified Eagle midium (hereinafter abbreviated as D'MEM),
Basal media such as F-12, RPMI-1640, insulin (2-10 μg/ml),
Selenium ( 10-11-10-8 M), transferrin (10-35 μg/ ml ), nucleic acid precursors (e.g. thymidine, hypoxanthine, etc., about 10-6 M), serum albumin (50-400 μg/ml), etc. A medium supplemented with can also be used as a basal medium. The royal jelly added to the medium of the present invention is 0.003-0.3

The preferred range is 0.01-0.2%. Royal jelly extraction, dialysis fraction, molecular weight
10-200μ for fractions of 200,000 or more, molecular weight fractions of 40,000-90,000, and royal jelly proteins.
g/ml is desirable. 0.5-350μg/ml for other milk and milk components; for placental blood fraction
Desirably, it is 50-300 μg/ml. Although the culture medium of the present invention can be used for culturing animal cells such as fibroblasts and lymphoblastoid cells, it is most preferably used for culturing animal cell-derived cells such as lymphocyte-derived cells. Using the medium of the present invention, it is possible to obtain cell proliferation almost comparable to that of a conventional medium supplemented with a large amount of serum. Furthermore, compared to the conventional method of adding 10% serum, the amount of royal jelly added can be as small as 0.01-0.2%, which has the advantage of being inexpensive and reducing congested substances. For example, when comparing the protein concentration in the medium, it is 3 mg/ml or more when 10% serum is added, whereas the protein concentration in the medium of the present invention is low at 0.4 mg/ml or less. Furthermore, since it is possible to add molecular weight fractions to the culture medium of the present invention, it is possible to use the medium according to the molecular weight of the effective substance. For example, when culturing cells that produce antibodies (with a molecular weight of 150,000 or more), royal jelly protein and/or royal jelly with a molecular weight of 5-
The 80,000 fraction, lactoferrin, the milk fraction with a molecular weight of 40,000 to 90,000, and the placental blood fraction are added and used as necessary. As described above, by using the culture medium of the present invention for the production of effective substances, separation of effective substances,
It has the advantage of being easy to purify. The present invention will be explained below with reference to Examples. Example 1 105 cells of a peripheral lymphocyte cell line (Bri7) from a healthy person are implanted in 2 mm of a medium containing D'MEM/F-12 (1:1) and the additives shown in Table 1. 5%
Culture is performed for 3 days under CO 2 and 37°C conditions. The results obtained are shown in Table 1.
