NettetImportantly, Hofbauer cells serve as a per- missive reservoir for its replication [15, 16], and because of the close proximity to umbilical cord blood vessels, these cells may also serve as a vehicle of viral dissemination into the fetal circulation [16]. NettetHofbauer cells, or placental macrophages, have been described as early as day 18 (Boyd and Hamilton, 1970) and are very numerous in early pregnancy, their abundance declining after mid-second trimester ( Ingman et al., 2010) ( Fig. 4A and B ). It is unclear whether they develop de novo from extraembryonic mesenchyme or are of yolk sac origin.
NettetAbstract. It is now generally considered that Hofbauer cells are fetal tissue macrophages of the human placenta.
