Animal Model of Anemia induced of chronic phlebotomy:Functional relationship between iron and erythropoiesis

Modelo animal de anemia inducida por flebotomía crónica: Relación funcional entre hierro y eritropoyesis

In the present work we studied the erythropoietic response to chronic phlebotomy-induced anemia and changes in cellular and systemic body iron distribution. Female mice (CF1 strain, n = 32) were divided into control and experimental groups, following a paired experimental design  Iron distribution in spleen and liver during chronic phlebotomy was assessed by morphological studies and erythropoietic activity by hematological studies. Statistical differences were determined by Student test. The significance level was set at p <0.05. During chronic phlebotomy we observed a significantly decreased of hemoglobin as an anemia indicator and reticulocytosis as an indicator of erythron restoration. Adult mouse spleen was the main tissue that contributed available iron to the erythron, being evident splenic iron depletion. The study of chronic induced anemia in mice allowed us to the development of patho physiological conditions similar to those observed in human pathologies. The model of chronic phlebotomy was useful to evaluate the erythropoiesis in the setting of anemia and its recovery, correlating with the distribution of an essential nutrient such as iron.
