We found some gooey material that had the right extracellular matrix in it, we put the cells in it, and lo and behold, in about four days, they got reorganized and on the right, is what we can make in culture.

In order to do that, however, we needed to have a method of distinguishing normal from malignant, and on the left is the single normal cell, human breast, put in three dimensional gooey gel that has extracellular matrix, it makes all these beautiful structures.
