title: Lymph nodes in congenital osteopetrosis of the op rat (ultrastructural study).
abstract: The electron microscopic study of lymph nodes from osteopetrotic op/op rats demonstrates the existence of an active lymphopoiesis and granulopoiesis. At an advanced stage of the disease, lymphopoiesis is associated to a granulopoiesis and to plasmacytosis.
