Hepatocytes and sinusoids
WebThe intimate relationship of the liver sinusoids to neighbouring hepatocytes is a significant factor affecting the health of hepatocytes, or transmission of the effects of injury within the sinusoidal space. Pathologists should recognize several patterns of injury involving the sinusoids and surrounding hepatocytes. WebHepatocytes are organised into plates separated by vascular channels , an arrangement supported by a reticulin (collagen type III) network. The hepatocyte plates are one cell …

WebHepatocytes and Sinusoids This image shows the close proximity between the blood in the sinusoids and hepatocytes. Endothelial cells line the sinusoids. These endothelial cells form a discontinuous endothelium that has wide gaps between cells and lacks a basement membrane and is therefore very permeable. Web1 nov. 2024 · The sinusoids are vascular channels between anastomosing plates of hepatocytes (Ross & Pawlina, 2016). In histological sections, the liver plates appear as linear rows of heaptocytes (Figure 1 ). The sinusoids receive a mixture of venous blood from the portal circulation (~75% and highly oxygenated) and arterial blood (~25% and …
