Ultrastructure of oval cells in children with chronic hepatitis B, with special emphasis on the stage of liver fibrosis: The first pediatric study

Figure 1 The view of hepatic progenitor cells in hepatic intracellular spaces. The nuclei contain dense heterochromatin clumped under nuclear envelope and sparse euchromatin. The cytoplasm shows rare poorly developed cell organelles. Between progenitor cells and the neighboring mature hepatic cells (H) point desmosomes are present (>) (× 12 000).
