E-morph: Animal-free method to test on hormone-active substances Featured

A test has been developed at the German Center for the Protection of Laboratory Animals (Bf3R) in Berlin that can detect hormone effects in cultured human cells. Using microscopy and artificial intelligence, the "E-Morph" test reliably finds substances that may have estrogen-like or even opposite (anti-estrogenic) effects.


The test is based on the observation that estrogen-like substances cause the connection of cells in the mammary gland. This makes it easier for breast cancer cells to a crucial step in the spread (metastasis) of tumors. In the E-morph test, a test substance is applied to cultured human breast cancer cells. is added to cultured human breast cancer cells. It is then examined whether the cell contacts loosen as they do under the influence of estrogen.

Future applications of the test include testing chemicals that are already on the market, as well as those that are about to be launched. The test can also be used to develop new drugs, improve diagnostic tests to detect breast cancer, and optimize therapies.

The scientists have presented the test in the journal Environment International.
