Under apparently normal conditions, the smooth muscle cells obtained from veins of human umbilical cord do not possess receptors for C3b or the Fc portion of IgG. These receptors were not expressed even after exposure to neutrophil lysate or a superoxide-generating system. The lack of these receptors argues against the possibility that smooth muscle cells participate in the pathogenesis of immune complex diseases through binding of C3b or Fc fragments.
在表面正常的情况下，从人脐带静脉获取的平滑肌细胞不具备C3b或IgG的Fc段受体。即使暴露于中性粒细胞裂解物或超氧化物生成系统后，这些受体也未表达。缺乏这些受体表明平滑肌细胞不太可能通过结合C3b或Fc片段参与免疫复合物疾病的发病机制。
