Embryonic hemoglobins in man and other mammals
A Fantoni, MG Farace and R Gambari
This report attempts to review the present state of research on embryonic
hemoglobins in humans and other mammals from a cytologic, molecular, and
clinical point of view. In all mammals, the yolk sac is the site
responsible for the "primitive" erythropoiesis, which produces an erythroid
population characterized by peculiar cytologic features and globin gene
expression. Morphological and molecular events that underlie prenatal
erythropoiesis are described herein giving rise to questions regarding
biology at large (i.e., the differential activity of genes capable of
similar functions); molecular biology of eukaryotic genes (i.e., globin
gene organization and structural subtleties); and clinical hematology
(i.e., syndromes associated with the appearance of embryonic hemoglobins.
