Vastavam web: US researchers published striking images of SARS-CoV-2 infected cells in the respiratory airways that are very graphic in nature. In a laboratory setting, the researchers at the University of North Carolina School of Medicine inoculated the new coronavirus into human bronchial epithelial cells, which were then examined 96 hours later using scanning electron microscopy.
Camille Ehre, Assistant Professor of Pediatrics, captured these images to illustrate how intense the SARS-CoV-2 infection of the airways can be in very graphic and easily understood images. The images show infected ciliated cells with strands of mucus (yellow) attached to cilia tips (blue). A higher power magnification image shows the structure and density of SARS-CoV-2 virions (red) produced by human airway epithelia.
Virions are the complete, infectious form of the virus released onto respiratory surfaces by infected host cells.According to the researchers, this imaging research will help illustrate the incredibly high number of virions produced and released per cell inside the human respiratory system.
