"Aging" pigments in term human placenta
American Journal of Obstetrics and Gynecology
|April 1, 1981
First-, second-, and third-trimester placentas were examined with fluorescent microscopy for the presence of lipofuscin pigments. Prior to 32 weeks' gestation these were not seen, but they were routinely found in the trophoblast of the term placenta. These pigments may or may not represent "aging" of the placenta.
