The effect of RGDS and RGES tetrapeptides, phospho-l-serine and RMV-7 upon mesangial cell phagocytosis of apoptotic RMA cells at the 3-h time-point. The higher inhibition of phagocytosis was seen following the addition of 2 mm RGDS in the mesangial cell/apoptotic RMA interaction medium while the control tetrapeptide RGES had no effect. The results are expressed as a mean percentage of the phagocytic signal in the well containing wild-type serum for each experiment ± s.e.m. The control well was standardized to 100%. Data shown are the result of four independent experiments. *P < 0·05; **P < 0·0001.
