Persistence of recipient-type endothelium after allogeneic hematopoietic stem cell transplantation. Haematologica, 96(1):119-127.

Abstract

Background: The possibility that allogeneic hematopoietic stem cell transplantation performed across the ABO blood group-barrier is associated with an increase of graft-versus-host disease, in particular endothelial damage, has not been elucidated so far. For this reason, we investigated the level of endothelial cell chimerism after allogeneic hematopoietic stem cell transplantation in order to delineate the role of hematopoietic stem cells in endothelial replacement. Design and Methods: The frequency of donor-derived endothelial cells was analyzed in 52 hematopoietic stem cell transplantation recipients, in 22 normal skin biopsies, in 12 graft-versus-host disease affected skin samples, various tissues from 5 autopsies and 4 secondary solid tumors by ABH immunohistochemistry, XY fluorescence in situ hybridization and short tandem repeat analysis of laser captured endothelial cells. Results: Skin biopsies from two minor ABO-incompatible (i.e. O in A) transplanted patients showed 3.3% and 0.9% H antigen-positive donor-derived endothelial cells by ABH immunohistochemistry. Tumor biopsies from two recipients showed 1.2% and 2.5% donor-derived endothelial cells by combined immunohistochemistry/ fluorescence in situ hybridization. All other skin samples, heart, liver, bone-marrow, and tumor tissues failed to reveal donor-type endothelial cells up to several years after ABO-incompatible hematopoietic stem cell transplantation. Conclusions: Endothelial cell replacement by bone marrow-derived donor cells after allogeneic hematopoietic stem cell transplantation is a rare event. It does not seem to represent a major mechanism of physiological in vivo blood vessel formation, tumor neo-angiogenesis, and vascular repair after graft-versus-host disease episodes or acceptance of ABO-incompatible grafts.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
