||P.601 right column bottom paragraph: "[Investigators] noticed during [their] measurements of pH that phagosomes containing bacteria were 3-6 µm in diameter (primary source). These unusually large or spacious phagosomes (SP) were similar in size to macropinosomes, endocytic vesicles formed from plasma membrane ruffles that appear in response to PMA or macrophage colony-stimulating factor (M-CSF) (refs 12, 13)."
