[Circulating granulomonocytic precursor cells and phenotype of peripheral blood monocytes in premature infants]

The functional state of granulomonocytic hemopoietic stem cells was investigated in 72 premature infants in the neonatal period. New data were obtained on the concentration of committed granulomonocytic precursors, and on the characteristics of the phenotype of monocytes--the final differentiation component of this series. These data have verified the present notions on the features of nonspecific adaptation reactions in premature newborns.
