脾索

LIF蛋白在心肌细胞、脾索和脾被膜的单层上皮细胞、肺成纤维细胞中有弱表达。

LIF has faint positive immunoreactivity in the normal porcine , myocardial cell , splenic cord and monolayer covering epithelium cell and pulmonary fibroblast .

白髓中未见明显的脾小结、淋巴鞘结构，红髓由脾索和脾窦构成。

The red pulp is composed of splenic cord and splenic sinus .

腹注LPS6～12h，脾索和淋巴小结周围呈现较多的一氧化氮合成酶（NOS）阳性细胞。

There were more NOS positive cells in spleen cord and around lymphoid follicle from 6 to 12h after LPS injection .

脾内衰老细胞主要分布于边缘区及脾索；

The senescent cells of the spleen were localized mostly in the marginal zone and the splenic cord .

脾脏白髓的脾小体和中央动脉淋巴套增生，淋巴细胞增多，红髓的脾窦和髓索轻度充血；

The small ball of white marrow of spleen and the surface of lymph of the central artery proliferated and red marrow spleen hole and marrow cable bleeded .
