Technology allowing cosmetic makers to test for allergic reactions to their products without controversial animal trials is in the works and could be in use by next year.
The technology developed by Hurel Corp., is designed to replace tests on mice and guinea pigs used to predict skin reactions from drugs and cosmetics.
The device uses laboratory-grown human skin cells to simulate the body’s allergic response to foreign chemicals. Preliminary experiments show promise, but rigorous tests are still needed to determine the technology’s accuracy.
The standard method for testing allergic reactions involves applying chemicals to the ears of mice, which are later killed and dissected for study.
The product from Hurel consists of a glass chip with human skin cells and chemicals that simulate the body’s immune system. When a foreign substance is dropped onto the chip, the cells and chemicals interact to mimic the human body’s natural allergic response. Read more ……
