English: Slow Transport of Large Merosomes toward the Central Vein Two large merosomes (on the left) are transported along a liver sinusoid, are temporarily arrested at a sinusoidal bifurcation, and reverse direction of movement. The resulting obstruction of the blood flow prevents another merosome (on the right) from entering the same sinusoid. Note the high malleability of the merosomes. The video shows intravital confocal microscopy of a mouse liver 52 h after intravenous sporozoites infection with PyGFP. Total recording time: 5 min and 23 s.
