Bombyx mori L.（鳞翅目：用透射电镜观察了红腹小蜂幼虫前胸造血器官的血细胞分化。在器官的致密胰岛中观察到三种和/或四种类型的干细胞。未成熟的血细胞在松散的胰岛的器官更分化和发达比紧凑的胰岛。在疏松的胰岛中可观察到原血细胞、浆细胞、粒细胞和类酒细胞四种类型的血细胞。每种类型的血细胞从每种类型的干细胞分化。但未观察到球形红细胞。每种类型的血细胞在疏松的胰岛中成熟，通过撕裂覆盖在胰岛上的脱细胞膜而排入血淋巴。这些观察有力地表明，除球形红细胞外，四种血细胞首先出现在胰岛中，然后以成熟的形式移动到疏松的胰岛区域。B中血细胞分化的更详细途径。森喜朗在这里有代表。
Bombyx mori L. (Lepidoptera: Bombycidae) larva was investigated with a transmission electron microscopy to determine hemocytic differentiation in the hemopoietic organ located in the prothorax. Three and/or four types of stem cells in compact islets of the organ were observed. Immatured hemocytes in loose islets of the organ were more differentiated and developed than in compact islets. Four types of hemocytes such as prohemocyte, plasmatocyte, granulocyte and oenocytoid were observed in loose islets. Each type of hemocyte was differentiated from each type of stem cell. However, none of spherulocyte was observed. Each type of hemocytes matured in loose islets was discharged into hemolymph by the tearing of acellular membrane covering the islets. These observation strongly suggests that the four kinds of hemocytes except for spherulocytes first appeared in islets and then moved to the region of loose islets in matured form. The more detailed pathway of hemocytic differentiation in B. mori was represented here.
