C3b and c3d receptor sites on human fibroblasts derived from several human tissues

Virchows Arch B Cell Pathol. 1978 Mar 29;27(2):155-7. doi: 10.1007/BF02888990.


The C3b and C3d receptor sites on one cell line of human diploid fibroblasts (WI-38) were reported in previous papers [3, 4]. In this paper we describe that C3b and C3d receptor sites can also be detected in fibroblast cell lines derived from other human tissues. We consider that C3b and C3d receptors are normally found on the cell surfaces of all human fibroblasts.
