研究了Petromyzon marinus幼虫整个生命周期的伤寒和后肾淋巴造血组织的超微结构。在这两个位置，淋巴造血组织都有结缔组织基质，并由内衬连续内皮的扩大的血窦系统冲洗。伤寒和后肾淋巴造血组织由属于红系、淋巴系、单核细胞和粒细胞谱系的成熟和发育的血细胞组成。在变态过程中，幼虫后肾完全退化，消化器官完全转变。由于这些修饰，伤寒索和后肾失去了它们的造血能力。这些变化是根据所谓的“造血诱导微环境”（主要是基质支持装置和血管化模式）在其中发挥的作用来讨论的。
The ultrastructure of the lympho-hemopoietic tissue of the typhlosole and opisthonephros of larval Petromyzon marinus was studied throughout the life cycle. In both locations, lympho-hemopoietic tissue houses a connective tissue stroma and is irrigated by a system of enlarged blood sinuses lined by a continuous endothelium. The typhlosolar and opisthonephric lympho-hemopoietic tissue consists of mature and developing blood cells belonging to erythroid, lymphoid, monocytic and granulocytic lineages. During metamorphosis there is a total degeneration of the larval opisthonephros and a full transformation of the digestive apparatus. As a consequence of these modifications the typhlosole and the opisthonephros lose their hemopoietic capacity. These changes are discussed in view of the role played in them by the so-called "hemopoietic inductive microenvironments", principally the stroma supporting apparatus and vascularization pattern.
