Researchers at the University of Pittsburgh’s School of Medicine and Graduate School of Public Health have found in an animal model that chronic exposure to arsenic can lead to stem cell dysfunction that impairs muscle healing and regeneration. More than 140 million people worldwide and 4 million Americans chronically ingest arsenic, which is naturally present in soil and bedrock-walled wells and has no color, odor or taste. Watch this video to learn more about the research, which suggests environmental exposures might explain why some people have a harder time recovering from injury or surgery.
