人淋巴管内皮细胞分离自淋巴管组织；淋巴管由毛细淋巴管汇合而成。其形态结构与静脉相似，但管径较细，管壁较薄，瓣膜较多且发达，外形呈串珠状。淋巴管根据其位置分为浅、深二种。它们管位于皮下，常与浅静脉伴行，收集皮肤和皮下组织的淋巴。深淋巴管与深部血管伴行，收集肌肉和内脏的淋巴。浅、深淋巴管之间有广泛的交通支。淋巴管在向心行程中，通常经过一个或多个淋巴结，从而把淋巴细胞带入淋巴液。主要功能是滤过淋巴液，产生淋巴细胞和浆细胞，参与机体的免疫反应。当局部感染时，细菌、病毒或癌细胞等可沿淋巴管侵入，引起局部淋巴结肿大。如该淋巴结不能阻止和消灭它们，则病变可沿淋巴管的流注方向扩散和转移。

海星生物分离的人淋巴管内皮细胞采用组织贴块法并结合内皮细胞专用培养基培养筛选制备而来，细胞总量约为5×10⁵cells/T25瓶。
