Hepatocytes are the chief functional cells of the liver and perform an astonishing number of metabolic, endocrine and secretory functions.
Hepatic Histology: Hepatocytes
In three dimensions, hepatocytes are arranged in plates that anastomose with one another. The cells are polygonal in shape and their sides can be in contact either with sinusoids sinusoidal face or neighboring hepatocytes lateral faces. A portion of the lateral faces of hepatocytes is modified to form bile canaliculi. Microvilli are present abundantly on the sinusoidal face and project sparsely into bile canaliculi.
Hepatocyte nuclei are distinctly round, with one or two prominent nucleoli. A majority of cells have a single nucleus, but binucleate cells are common. Hepatocytes are exceptionally active in synthesis of protein and lipids for export.
