Abstract

This invention is a method and kit for preparing a Tumor in Dish model for use in screening anti-cancer agents and analyzing cancer growth and development.

Claims

1. A method for preparing a Tumor in Dish model comprising

(a) combining normal cells consisting of isolated human umbilical vein endothelial cells, isolated human lymphatic endothelial cells, isolated human fibroblast cells, and isolated human epithelial cells and with isolated cancer cells;

and

(b) culturing the combination of cells in culture medium for a time sufficient to form a tumor thereby preparing a Tumor in Dish model, wherein the culture medium consists of Microvascular Endothelial Cell Growth Medium;

Airway Epithelial Basal Medium;

Dulbecco'"'"'s Modified Eagle'"'"'s Medium, Mammary Epithelial Cell Basal Medium, or Roswell Park Memorial Institute 1640 Medium;

Fibroblast Growth Medium;

Hydrocortisone;

Fibroblast growth factor 6;

R3-Insulin-Like Growth Factor-I;

Ascorbic Acid;

Vascular Endothelial Growth Factor;

Human Epidermal Growth Factor;

Heparin;

Fetal Bovine Serum;

Antibiotics;

L-Alanyl-L-Glutamine;

Extract P;

Plasma Protein Fraction;

Epinephrine;

Transferrin;

Thyroxine 3;

Insulin; and

B27 supplement;

wherein there are no other culture medium ingredients added during the time sufficient to form a tumor.

2. The method of claim 1, wherein the tumor comprises colon cancer, lung metastasis, ovarian cancer, medulloblastoma or glioblastoma.

3. The method of claim 1, wherein step (a) comprises

(i) combining normal cells consisting of isolated human umbilical vein endothelial cells, isolated human lymphatic endothelial cells, isolated human fibroblast cells and isolated human epithelial cells;

(ii) culturing the combination of normal cells of (i);

(iii) adding isolated cancer cells to the cultured normal cells of (ii).

4. The method of claim 1, wherein the step of culturing the normal cells is carried out in an ultra low attachment culture vessel.

5. The method of claim 1, further comprising the steps of:

(c) adding a test compound; and

(d) determining whether the test compound inhibits, attenuates, prevents or reduces tumor growth, proliferation, size or metastasis.
