Coefficients of correlations between absolute numbers of circulating stem cells' populations and systemic levels of complement anaphylatoxins measured in patients with gastric cancer.

Stem cells population/parameter	C3a	C5a	MAC
VSEL	0.80*	NS	0.54#
MSC	0.74*	NS	NS
HSPC	NS	NS	NS
EPC	NS	NS	NS

^#p <0.05;

^*p <0.01; p—level of significance; NS—not significant.

MAC—membrane attack complex (C5b-9) of the complement system; VSEL—very small embryonic-like stem cells; MSC—mesenchymal stem cells; HSPC—hematopoietic stem/progenitor cells; EPC—endothelial progenitor cells.
