Dr. Wlodarczyk uses genetically modified mice to reveal how genetic mutations modulate the mechanisms underlying susceptibility to the induction of congenital defects.

Research Interests

I am a research veterinarian who has long been interested in toxicology, especially those aspects concerning human reproduction. More specifically, I am trying to understand why some babies are born with congenital defects while others are healthy and develop normally. Almost 5% of all newborns worldwide are born with birth defects which are directly responsible for millions of infant death worldwide. The study of abnormal development resulting in birth defects is called “teratology”. This field of study really began in the 1960s following the Thalidomide tragedy. Thalidomide was a drug intended for pregnant women to help them reduce the symptoms of morning sickness. Unfortunately it had devastating effects on developing embryos. In 46 different countries, over 10, 000 babies with no hands or legs, or with severely deformed limbs were born in just a few years. Ever since this tragedy occurred, scientists began to study how drugs, pesticides or any other environmental stimuli can disrupt normal embryo/fetal development and cause babies to be born with congenital defects. These studies proved to be very difficult, and although significant progress has been made, about 65% of all identified birth defect cases have no known causes. That means, for every three babies that we see in clinics with birth defects, we have no explanation to give to two sets of parents. This is not an acceptable situation. Today we know that all embryos developing in their mother`s womb are vulnerable to many chemicals that might seem to be non-toxic to adults. We are also now aware that humans carry many mutations in genes which can make certain individuals more susceptible to environmental toxins.
Since one obviously can’t perform toxicological experiments on humans, different models have been used to study birth defects; from cell cultures through frogs, chicken embryos, laboratory rodents and primates to mathematical computational models. My research uses laboratory mice, the conventional and the genetically engineered variety. Pregnant female mice can be used to test new drugs or other chemical compounds intended for ultimate use in humans. Since over 85% of the genes controlling human development have also been found in mice, I recently started using genetically modified mice that carry mutations in specific genes to learn more about the causes of birth defects. Results of these studies not only allow me to understand how specific birth defects arise but also help to identify the population of humans (having a similar mutation) who may be at higher risk of conceiving a baby with congenital defects. Studying birth defects will ultimately result in prevention and eradication of these merciless adverse pregnancy outcomes.
