Histochemical and transmission electron microscopic studies of spleen in prenatal stages of goat

A study was conducted on twenty six goat foetuses of different ages to reveal the histochemical and ultrastructural observations of spleen. A strong PAS reaction was seen in all the splenic components of all ages of goat foeti. The APUD cells and mast cells were scattered in the splenic cords. Small and oval argentaffin cells were appeared in white pulp in day old neonates. A reticular cell synsitium carrying sequestered lymphocytes at central parenchyma of spleen of goat aged 106 day of gestation and with advancing age it revealed entrapment of more sequestered lymphocytes at different stages of gestation. In the spleen of day old kids pericapillary macrophage ingesting disintegrating lymphocytes was evident.
