By testing these gene fusions in mice and in cell cultures, the researchers showed that the fusions are what cause prostate cancer to develop. But its not just one set of genes that fuse.

In addition to growing the cells in the lab and transplanting them back into the eye, the researchers are looking at ways to stimulate growth and persuading the eye to repair itself using its own cells.
