海鞘血液的超微结构研究揭示了特殊的细胞类型，其特征是电子致密的细胞质物质的组织具有多态。提出了桑椹胚细胞分化的新途径。X射线显微分析表明，钒主要分布在空泡细胞、颗粒细胞和桑丘细胞中。铁，这一物种积累的程度低于钒，在空泡化的变形细胞中发现，与钒一起存在于颗粒细胞中。根据血细胞对金属的选择性吸收与其特化和分化之间的关系对我们的结果进行了讨论。
Ultrastructural studies of Ascidia malaca blood reveal particular cell types, which are characterized by a polymorphism in the organization of the electron dense cytoplasmic material. A new pathway of morula cell differentiation is suggested. X-ray microanalysis shows that vanadium is localized in vacuolated, granular and morular cells. Iron, which is accumulated by this species to a lesser degree than vanadium, is found in vacuolated amebocytes and, together with vanadium, in granular cells. Our results are discussed in the light of the relations between selective metal absorption in blood cells and their specialization and differentiation.
