电镜研究表明，兔脾红髓是由网状细胞、网状网和通过其循环的血液元素组成。所描述的三种类型的网状细胞在它们所排列的空间类型上没有明确的模式，并且并不总是与基膜相邻。相同或不同的细胞可以排列在相同或相反的基膜上。整个红髓区通过几个间隙的孔和连接处相互交流，在没有基底膜存在的区域，网状细胞的细胞质突起形成了一个间隙网。末端小动脉以塌陷型通道结束，由内皮细胞变为I型网状细胞。这些迅速连接扩张的区域。脾脏的网状网络有四种类型：均质、纤维状、它们的组合和只有网状细胞。在网状细胞质中发现孤立的纤毛，并显示与基体和中心粒有关。该研究支持了成年兔脾红髓是一个功能动态区域的假设，该区域在细胞和血管通道状态方面不断改变其组织学结构。
Electron microscopic studies reveal that the red pulp of the rabbit spleen is composed of reticular cells, reticulum and elements of the blood circulating through it. The three types of reticular cells described follow no definite pattern as to types of spaces they line and are not always adjacent to a basement membrane. Similar or dissimilar cells may line a basement membrane on the same or opposing sides. The entire red pulp area is intercommunicating through pores and junctions of the several spaces and in that area in which no basement membrane exists, the cytoplasmic projections of the reticular cells form a meshwork of spaces. Terminal arterioles are seen to end in collapsed type channels with a change from endothelium to Type I reticular cells. These rapidly join dilated areas. The reticular network of the spleen appears as four types: homogeneous, fibrillar, a combination of these, and reticular cells only. Isolated cilia are found in the reticular cell cytoplasm and are shown to be associated with a basal body and a centriole. The investigation supported the hypothesis that the red pulp of the spleen in the adult rabbit is a functionally dynamic area constantly changing its histological structure, both regarding cells and state of the vascular channels.
