Fig. 2From: Amiodarone induces cell wall channel formation in yeast Hansenula polymorpha Electron microphotographs of untreated Hansenula polymorpha cells (a) and cells treated with amiodarone (b–e). Electron-dense channels (black arrow) span the cell wall. G glucan layer, black arrowheads—mannoproteins. Electron-dense areas can be seen where the channels exit the cell (double black arrowheads).
