How do you perfuse a mouse liver?
Perfuse liver with calcium-free buffer without collagenase: 10 mL of Hanks’ Balanced Salt Solution (HBSS) without calcium or magnesium + 0.5 Milimolar (mM) EGTA at a flow rate of 2 mL/min until fluid drained from the IVC is no longer red (containing blood). This is done with a pump with no recirculation.
How do you isolate mouse hepatocytes from the liver?
Single-cell hepatocyte isolation using Percoll gradient centrifugation
- Centrifuge the strained cells at 50 × g for 5 min at 20°C–24°C to separate hepatocytes from non-parenchymal cells.
- Discard the supernatant.
- Resuspend the pellet in 20 mL plating media and wash the cells twice at 50 × g for 5 min.
What is hepatocyte isolation?
This protocol is aimed at isolating hepatocytes from mouse liver. Following anesthesia, the vena cava is cannulated and the liver is perfused to chelate calcium and wash out blood. Then, collagenase is perfused to the liver in order to dissociate extracellular matrix.
What is special about liver perfusion?
Liver perfusion has the unique advantage of allowing instantaneous delivery, or cessation of delivery of a toxin or physiological substance, while monitoring the integrated metabolic response of the liver. These preparations are limited by time, that is, maintenance beyond a few hours is not practical.
How many cells are in a mouse liver?
For human, rabbit, rat and mouse livers, the hepatocellular values were in the same range, more precisely 139+/-25, 114+/-20, 117+/-30 and 135+/-10 million cells per gram of liver, respectively.
What is the perfusion rate of liver?
Liver perfusion decreased in patients with cirrhosis (67 ± 23 mL ⋅ min–1 ⋅ 100 mL–1 versus 108 ± 34 mL ⋅ min–1 ⋅ 100 mL–1 in control subjects [p = 0.009] and 98 ± 36 mL ⋅ min–1 ⋅ 100 mL–1 in patients with noncirrhotic chronic liver disease [p = 0.003]), and the arte- rial fraction and the mean transit time increased ( …
What is perfusion abnormality liver?
Hepatic perfusion disorder (HPD), or hepatic perfusion abnormality, refers to perfusion differences between segments, subsegments, and lobes of the liver related to various causes (1). In 1997, Gryspeerdt et al (2) defined the phenomenon of HPD on contrast material–enhanced computed tomographic (CT) images.

How big is a liver cell?
Normal Liver and Gallbladder. Hepatocytes constitute the predominant cell type of a normal liver (Fig. 9-1A&B). They are slightly oval to polygonal plump cells, with a diameter of 25 to 30 μm (approximately 3 to 4 erythrocyte diameters).
