ABSTRACT
This study was purposed to investigate the accumulative regularity of tumor-associated noncellular components in supernatant of stored packed red blood cells (PRBC) during storage. The supernatant of PRBC was obtained by centrifugation with 1 006×g for 10 min at day 0, 7, 14, 21, 28 and 35 d. The enzyme-linked immunosorbent assay (ELISA) was used to detect the expression of T cells and the accumulative levels of secreted RANTES/CCL5, tumor necrosis factor-alpha (TNF-α), platelet derived growth factor (PDGF), vascular endothelial growth factor (VEGF) and monocyte chemotactic protein-1 (MCP-1). The results showed that the high concentration of RANTES/CCL5 and TNF-α was found in fresh PRBC, and their accumulative concentration did not increase along with the prolonging of storage time. The VEGF level in PRBC at day 0 of storage was 229.9 pg/ml, and increased to 749.08 pg/ml at end of day 7, then it was stable, and increased to 760.67 pg/ml at end of day 35. The PDGF level in supernatant of PRBC was 13.54 ng/L at dag 0 of storage, and increased stably during storage, then decreased at day 28, however PDGF rapidly rose to 22.13 ng/L at the end of day 35 (P < 0.05). The MCP-1 level in supernatant of PRBC was 39.98 ng/L at day 0 of storage, then slowly increased during storage time, at end of day 35 MCP-1 level increased to 49.83 ng/L. It is concluded that along with the prolongation of storage time, the growth factors in the supernatant of PRBC display the tendency of accumulative increment and RANTES/CCL5 and TNF-α show relative high level at day 0 of storage, moreover, no obvious increase of accumulation is observed along with prolonging of the storage time, suggesting no relation of concentration with storage time.
