Hofbauer cell
Hofbauer cells are oval eosinophilic histiocytes with granules and vacuoles found in the placenta, which are of mesenchymal origin, in mesoderm of the chorionic villi, particularly numerous in early pregnancy. == Etymology == They are named after J. Isfred Isidore Hofbauer (1871-1961), a German-American gynecologist who described the cell type in his book Grundzüge einer Biologie der menschlichen Plazenta, mit besonderer Berücksichtigung der Fragen der fötalen Ernährung (Biology of the Human Placenta with a special emphasis on the question of fetal nourishment).
