UCR Study Finds E-Cigarettes Damage Brain Stem Cells
A research team at the University of California, Riverside has found that electronic cigarettes damage brain cells. KVCR's Benjamin Purper has more.
The team found that e-cigarettes produce a stress response in neural stem cells, which are critical cells in the brain.
Stem cells become specialized cells in the body like brain or blood cells. They’re a lot more sensitive to stress than specialized cells, which means we can study them to find out how the body reacts to stress.
E-cigarettes deliver nicotine to these stem cells, placing them into a state of so-called “stress-induced mitochondrial hyperfusion.”
This state can lead to cell death or disease after chronic use, according to the study.
The study’s authors say it shows that e-cigarettes are not harmless, and that even short-term use can lead to damaged brain cells.
They also stressed that youth and pregnant women need to pay especially close attention to their use of e-cigarettes, as the nicotine can affect the brain in multiple ways during prenatal or adolescent development.
