Comparative characteristics of healthy newborns cord blood cell composition and G-SCF-mobilized blood from healthy donors

Abstract

Cord blood cell composition is a short-lasting delivery stress consequence and is similar on adult G-CSF-mobilized peripheral blood.G-CSF realizes biological effect by number of secondary messengers, many of which are also natural effectors of stress. In this research comparative characteristics of cell composition, including lymphocytes subpopulations, CD34+ and CD133+ cells, hematopoietic progenitor cells colony-forming activity and mobilizing cytokines concentration (IL-8, MMP-2, MMP-9), between term newborns cord blood and G-CSF-mobilized peripheral blood is shown.Mobilized cytokines concentration ratio in combination with CD34+ cells count in cord blood and mobilized peripheral blood suggests that delivery stress possibly is not single cause of cord blood features.
