Pregnant Women Warned Against Mentholated E-Cigarettes Due to Potential Risks: Study
Advertisement
Vaping during pregnancy is becoming more common, but its impact on early human development is not well understood. A new study by scientists at the University of California, Riverside, now reports that the flavor chemical menthol used in electronic cigarettes could pose risks to a developing baby.
The study, published in STEM CELLS Translational Medicine, used human embryonic stem cells, or hESCs, to characterize early stages of embryonic development and examined how low concentrations of menthol affect important cellular processes.
The researchers found the concentration of menthol in the blood of pregnant women who vape is enough to activate stress-related channels called Transient Receptor Potential channels in the hESCs.
Transient Receptor Potential channels are a large family of ion channels located in the membranes of many different cell types, including in reproductive tissues and embryos. They are involved in a wide range of sensory and physiological processes, including detecting heat, cold, pain, pressure, taste, and smell.
