4.2.1 POJA-L3645+3646
Title: Fetal liver with blood forming islets during the hepatolienal period (human)
Description: Stain: Hematoxylin-eosin. (A) Survey (ca. 4-5 months old) and (B) detail of fetal liver (ca. 2-3 months old).
(1) Liver parenchymal cells.
(2) In the sinusoid space islets or clusters of differentiating erythropoietic colonies are present existing of normoblasts and precursor cells. (3) Nearly mature normocytes with the nucleus still present. Arrows point to blood stem cells localized within the space of Disse.
(4) Sinusoid endothelial cell with a flattened form. Mitotic cells can be observed. By the sixth embryonic week mesenchymal cells invade the liver space of Disse and become involved in hematopoiesis, up to the fifth month of pregnancy.
Keywords/Mesh: liver cell, fetus, hematopoiesis, histology, POJA collection
