The ultrastructure of B-cells in the rat pancreatic islets has been studied under various experimental conditions (thyroidectomy, continuous thyroxine treatment, regeneration after partial pancreatectomy, thyroidectomy with partial pancreatectomy, partial pancreatectomy, partial pancreatectomy with continuous thyroxine treatment). Five types of B-cells have been distinguished. It has been supposed that "light" B-cell 1 is related to the stage of secretory granule extrusion, "light" B-cell 2 reflects the extrusion of secretory material and the early stages of secretory granule synthesis; "dark" B-cell 1 is involved in the intensive synthesis, formation and extrusion of secretory material, and "dark" B-cell 2 in the intensive secretory granule synthesis, formation and storage.
在各种实验条件下（甲状腺切除、连续甲状腺素治疗、部分胰腺切除术后再生、甲状腺切除联合部分胰腺切除、部分胰腺切除、部分胰腺切除联合连续甲状腺素治疗），对大鼠胰岛中B细胞的超微结构进行了研究。已区分出五种类型的B细胞。据推测，“亮”B细胞1与分泌颗粒的排出阶段有关，“亮”B细胞2反映了分泌物质的排出以及分泌颗粒合成的早期阶段；“暗”B细胞1参与分泌物质的密集合成、形成和排出，而“暗”B细胞2参与分泌颗粒的密集合成、形成和储存。
