Assistant Professor, Zhen Ma was a 2017 Young Researcher Lush Prize Winner. He was one of five awarded this prize
The Lush Prize rewards initiatives across science and campaigning that work to end or replace animal testing, particularly in the area of toxicology research.
Now in their sixth year, they have awarded £1.8 million in prizes, aiming to bring forward the day when safety testing takes place without the use of animals.
They seek to reward those working on replacing, rather than reducing or refining animal experiments.

Ma’s award was for his work titled, “Human Developing Heart Model for Animal-Free Embryotoxicity Drug Screening”
It has been reported that nearly one out of every 20 women using antidepressants three months before becoming pregnant or during the pregnancy. Deciding to continue or stop using antidepressants during pregnancy is one of the hardest decisions a woman must make. There has been a long ongoing debate about whether the use of antidepressants during pregnancy is associated with an increased risk of congenital defects.
The embryotoxicity studies for preclinical drug development have been suffering from limited human studies and short of standardized assays to screen and classify the drug embryotoxicity before clinical trials. My research career focuses on the development of human-specific embryotoxicity testing model system based on human induced pluripotent stem cells (hiPSCs) to replace the animal-based studies, and this screening system can provide more precise assessment of human-specific drug effect on fetus development.
My project for this Lush Prize focuses on the establishment and validation of a developing heart model that recapitulates early human heart formation in a tissue culture dish. Using this heart model, I aim to establish a risk classification system of safe pregnancy medication for fetus heath, and further rank the embryotoxicity risk level of current available antidepressants in market.
