Fig. 2. Images of HUVECs prepared using HPF for transmission EM show a huge improvement in structural preservation. (A) A low magnification image showing immature WPBs (arrows) in the Golgi region. Bar, 500 nm. (B) A VWF tubule is seen within the TGN (arrowheads). Bar, 200 nm. (C,D) Immature WPBs with stalk-like attachments to the Golgi (arrows), Bars, 200 nm (C) and 500 nm (D). G, Golgi; M, mitochondrion; RER, rough endoplasmic reticulum; TGN, trans-Golgi network.
