Abstract

The erythropietin sensitivities of dissociated cell cultures and explanted fragments of fetal livers of congenitally anaemic Slj/Slj mice, and their normal littermates, have been compared. The erythropoietin responsiveness of Slj/Slj foetal liver cells is deficient in both types of culture. The maximum liver complement of erythroid colony forming cells (CFUe) occurs on the 16th day of development when 'normal' livers contain approximately 6 X 10(5) erythroid colony forming cells/liver. In Slj/Slj fetuses the maximum reached is only 1 X 10(5). Granulocyte-macrophage colony forming cells (CFUc) in Slj/Slj fetal livers are also reduced to approximately 60% of normal numbers. Erythroid colony forming cells are also reduced in the spleen and femoral bone marrow of Slj/Slj mice in the 2-3 days preceding birth. Granulocyte-macrophage colony forming cells are rare in the femoral marrow of pre-natal Slj/Slj mice, but their production in the Slj/Slj pre-natal spleen appears unaffected.

Birth Defects

Birth defects encompass structural and functional alterations that occur during embryonic or fetal development and are present since birth. The cause may be genetic, environmental or unknown and can result in physical and/or mental impairment. Here is the latest research on birth defects.

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.
