反応手順

In a specific non-limiting embodiment of the invention Hu74 Medium is prepared as follows. Glutamine is added to Ham's F12 (GIBCO, Carlsbad, Calif.) at a concentration of 2 mM. Gentamicin is added to the culture medium to obtain a final concentration of 50 μg/ml. Fetal bovine serum (FBS, GIBCO, Carlsbad, Calif.) is added to the medium to obtain a 10% concentration (volume/volume). The medium containing FBS and gentamicin is stored at 4° C. and prepared fresh every two weeks. bFGF (PeproTech, Rocky Hill, N.J.) is dissolved in F12 medium to 2,500 ng/ml and stored in small vials at −70° C. The stored solution is added to the culture medium to obtain a final concentration of 25 ng/ml once a week. HGF (PeproTech, Rocky Hill, N.J.) is dissolved in F12 medium to 10,000 ng/ml and stored in small vials at −70° C. The stored solution is added to the culture medium to obtain a final concentration of 100 ng/ml once a week. An α-MSH solution is obtained by dissolving the α-MSH powder (Sigma, St. Louis, Mo.) to 100 μg/ml and is stored at −70° C. The stored solution of α-MSH is added to the culture medium to obtain a final concentration of 100 ng/ml once a week. (L)-Epinephrine bitartrate (Sigma, St. Louis, Mo.) is dissolved in PBS at 0.15 mg/ml with sodium ascorbate (Sigma, St. Louis, Mo.) (0.5 mg/ml) and stored at −70° C. Ephinedrine and ascorbic acid are added to the culture medium to obtain a final concentration of 1.5 μg/ml of epinephrine and 5 μg/ml sodium ascorbate once a week.
