Considering that recovery of post-infarction LV function is favourably correlated to bone marrow derived stem cell mobilization induced by endogenous Granulocyte-Colony Stimulating Factor (G-CSF) [8-9], therapeutic stem cell mobilization was proposed as an alternative method to ameliorate post-infarction LV function. Several basic studies have supported this notion suggesting that stem cell mobilization might improve LV function by increasing stem cell homing in the damaged myocardium in addition to a favourable direct effect of G-CSF on LV myocardium [10-12].
