The effect of serum from patients of chronic renal failure on colony forming units (CFU-S) in mice.

: Repopulating ability of mouse bone marrow stem cells, treated with pre-dialysis, post-dialysis and control sera was assessed by colony forming units (CFU-S). Significant lower colony counts were observed in pre-dialysis group as compared to control group. There was an improvement in the colony counts when the cells were treated with post-dialysis sera. The study suggests the presence of inhibitor/s of CFU-S in the uraemic sera which is/are partially removed by haemodialysis.
