Fig. 2. Digest cells on the third day ABM, isolated and observed by differential interference contrast (DIC) microscopy. (A) Digest cells separated from the midgut were observed without a coverslip. Arrowheads show the site of attachment to the gut epithelium. Scale bar, 55 µm. (B) Digest cell observed with a coverslip, at higher magnification. Hemosomes are concentrated in the perinuclear area (arrowheads). Asterisks indicate digestive vesicles. Scale bar, 5 µm. NU, nucleus.
