"Although macrophages also attacked blood cells expressing CD47 when mice were given the antibody, the researchers found that the decrease in blood cells was short-lived; the animals turned up production of new blood cells to replace those they lost from the treatment"

That's great -- does anyone know if any other cells in the body express CD47? Especially ones that can't be replaced so easily?
