Cell experiment:[1]
Cell lines	Vascular smooth muscle cells (VSMCs)
Reaction Conditions	0, 1, 5, 10 μM losartan for 48 h incubation
Applications	Losartan dose-dependently decreased the angiotensin Ⅱ (Ang Ⅱ)- or 15% fetal bovine serum (FBS)-induced VSMC proliferation by inhibiting the expression of cell cycle associated proteins, such as p-Rb, cyclin D, and cyclin E.
Animal experiment:[2]
Animal models	Wistar-Kyoto (WKY) rats and stroke-prone, spontaneously hypertensive rats (SHR-SP)
Dosage form	10 mg/kg/day Administered by oral route for 2 weeks
Applications	In SHR-SP, losartan decreased systolic blood pressure, increased the number of circulating endothelial progenitor cells (EPCs) and colony formation, and inhibited oxidation. In addition, losartan was able to stimulated EPC migration. These data suggest that losartan can improve the proliferation and function of EPCs in hypertension, with the potential to repair hypertensive vascular injuries.
