Basal epithelial stem cells in lung (IMAGE)
Caption
Basal epithelial stem cells (green) containing the protein IL-33 (red) are visible in a sample of lung tissue (pictured). Researchers at Washington University School of Medicine in St. Louis have found that such stem cells multiply during and after a viral respiratory infection, sometimes triggering a detrimental remodeling process that can cause persistent lung disease long after the virus has been cleared.
