Figure 1
Figure 1 Flow diagram of the preparation of isolated human hepatocytes with a modified four-step retrograde perfusion technique. Buffers: PBE: Perfusion buffer with EDTA; PB: Perfusion buffer; PBD: Perfusion buffer with dispase; PBC: Perfusion buffer with collagenase; WB: Washing buffer; WBD: Washing buffer with DNase.

Figure 2 Preparation of liver wedges. Only patients who had undergone left hemi-hepatectomies were deemed suitable for obtaining normal resected liver tissue from (A). Cut-off end of a suitable pipet tip to obtain an optimal size to match the vessel opening and cannulate the chosen vessel (B, C). Primary human hepatocytes must be isolated under stringent and rigorous sterile conditions (D).

Figure 4 Samples of liver hemangioma can provide better results, in terms of cell yield, than intrahepatic duct calculi. In addition, the size of the tissues can affect the outcome of hepatocyte isolation.
