dc.description.abstract | The state in which cells can inhabit other cells without damage is known as emperipolesis. Emperipolesis has been found in various physiological and pathological conditions. We performed a study of emperipolesis of erythroblasts within Kupffer cells in the human fetal liver. We found that Kupffer cells, identified by CD68 immunolabeling, contained 4-8 erythroblasts in a hypertrophic cytoplasm on light microscopy. Emperipoletic erythroblasts were present in various maturation stages from proerythroblast to reticulocyte. By electron microscopy, we found that erythroblasts occupied membrane-bound vacuoles that were separated from each other by thin partitions of Kupffer cell cytoplasm. Neither emperipoletic erythroblasts nor their Kupffer cell hosts showed evidence of damage. Emperipoletic cells in mitosis were found, which suggests the capacity for the proliferation of erythroblasts within Kupffer cells. Some Kupffer cells were seen to contain both emperipoletic cells and phagosomes, without evidence of interaction. Erythroblasts and other hemopoietic cells were also found to be closely associated with the sinusoidal surface of Kupffer cells. However, intercellular junctions, if present, were inconspicuous. On occasion, Kupffer cells engorged with erythroblasts nearly occluded the sinusoidal lumen. Our results demonstrate that emperipolesis of erythroblasts within Kupffer cells occurs in human fetal hepatic hemopoiesis. We suggest that emperipolesis may be one of the mechanisms that support the maturation of erythroblasts in the fetal liver. Anat Rec 256:158-164, 1999. (C) 1999 Wiley-Liss, Inc. | - |
