Vaping can lead to Neural Stem Cell Damage
UNITED STATES – According to an online news report at nydailynews.com, using electronic cigarettes, or e-cigarettes, can cause damage to neural stem cells that are essential for brain function, per a new study.*
Researchers at the University of California uncovered, pursuant to their research, that e-cigarettes cause stress to neural stem cells. While e-cigarette users think they are safer and cleaner than standard tobacco cigarettes, evidence is demonstrating that nicotine can cause harm whether it is smoked in a traditional cigarette or vaped. Another study shows that e-cigarette flavorings can damage cardiovascular cells.
One researcher notes that these products are “not harmless.” “Even short-term exposure can stress cells in a manner that may lead, with chronic use, to cell death or disease. Our observations are likely to pertain to any product containing nicotine,” the researcher noted in a statement.
The e-cigarettes initiate a complex series of cellular events that cause damage to the DNA of stem cells, per the study researchers.
“The neural stem cells get damaged and could eventually die,” the researcher said. “If that happens, no more specialized cells – astrocytes and neurons, for example – can be produced from stem cells.”
These cells are of vital importance, and young individuals who use e-cigarettes are particularly vulnerable due to the fact that their brains are still developing.
This means that younger individuals and pregnant women could be especially vulnerable to harm caused by e-cigarettes. One of the researchers noted that the brains of younger individuals are in a critical state of development, and that e-cigarettes used by them can cause significant brain damage. “Nicotine exposure during prenatal or adolescent development can affect the brain in multiple ways that may impair memory, learning, and cognition,” the researcher said in a statement. “Furthermore, addiction and dependence on nicotine in youth are pressing concerns. It’s worth stressing that it is nicotine that is doing damage to neural stem cells and their mitochondria.”
