Abstract

This study was designed to investigate the effect of human cytomegalovirus (HCMV) on the proliferation of colony forming unit granulocyte-macrophage (CFU-GM), CFU-erythroid (CFU-E), burst forming unit-erythroid (BFU-E), CFU-multipotential (CFU-Mix) and CFU-megakaryocytic (CFU-Mk) progenitor cells of cord blood in vitro as well as the possible mechanism. Twenty cord blood specimens were collected from the umbilical vein of normal full-term neonates delivered spontaneously. This study consisted of five groups: 3 Infection groups in which 0.1 mL 10(3), 10(4) and 10(5) plague forming unit (PFU) HCMV-AD169 virus solution was added to the culture system, an Inactivated control group in which the equal volume of inactivated virus solution was added, and a Blank control group (normal progenitor cells culture system without HCMV virus infection). Colony forming unit-assay was applied to detect the effects of HCMV-AD169 strain on the colony formation, inhibition rate and colony-maintaining duration of CFU- GM, CFU-E, BFU-E, CFU-Mix and CFU-Mk of cord blood. PCR technique was used to demonstrate the existence of HCMV-DNA in the colony cells of cultured CFU-GM, CFU-E, CFU-Mix and CFU-Mk. HCMV-AD169 (10(3)PFU) in low concentration had inhib...Continue Reading

Anemia

Anemia develops when your blood lacks enough healthy red blood cells. Anemia of inflammation (AI, also called anemia of chronic disease) is a common, typically normocytic, normochromic anemia that is caused by an underlying inflammatory disease. Here is the latest research on anemia.

Blood And Marrow Transplantation

The use of hematopoietic stem cell transplantation or blood and marrow transplantation (bmt) is on the increase worldwide. BMT is used to replace damaged or destroyed bone marrow with healthy bone marrow stem cells. Here is the latest research on bone and marrow transplantation.
