abstract = {Neoangiogenesis plays a key role in diverse
pathophysiological conditions, including liver regeneration.
Yet, the source of new endothelial cells (ECs) remains
elusive. By analyzing the regeneration of the liver
vasculature in irradiation-based myeloablative and
nonmyeloablative bone marrow transplantation mouse models,
we discovered that neoangiogenesis in livers with intact
endothelium was solely mediated by proliferation of resident
ECs. However, following irradiation-induced EC damage, bone
marrow-derived mononuclear cells were recruited and
incorporated into the vasculature. Further experiments with
direct bone marrow infusion or granulocyte
colony-stimulating factor (G-CSF)-mediated progenitor cell
mobilization, which resembles clinically relevant stem cell
therapy, demonstrated that bone marrow-derived cells did not
contribute to the regeneration of liver vasculature after
two-thirds partial hepatectomy (PHx). Taken together, the
data reconcile many of the discrepancies in the literature
and highlight that the cellular source of regenerating
endothelium depends on the fitness of the residual
vasculature.},
