People who have unbalanced lifestyles and habits such as consuming high fat and sugar foods, as well as the lack of physical activity, have an increased risk of obesity and related metabolic diseases. The condition of obesity occurs due to an excess of nutrients which leads to low-grade inflammation. Inflammation induced by obesity causes unstable bone marrow homeostasis which is associated with proliferation and differentiation of Hematopoietic Stem Cells (HSCs). This study aimed to observe the erythroid progenitor (TER-119) and complement regulator (CD59) on bone marrow cells in mouse models fed a high fat-fructose diet (HFFD). This research was conducted by modeling obese mice using high fat and fructose food for 20 weeks, and then treating them with elicited soybean extract (ESE) for four weeks with several doses: low dose (78 mg/kgBB), moderate dose (104 mg/kgBB) and high dose (130 mg/kgBB). Cell TER119+CD59+ expression decreased in the HFFD group compared to the normal group. In the low, moderate and high dose group, TER119+CD59+ expression significantly increased compared to the HFFD group. These results demonstrate that soybean elicited extract can improve the hematopoietic system by increasing TER119+CD59+ expression in a high fat and fructose diet mouse model. © 2017 Author(s).
