ABSTRACT

Induced pluripotent stem cells (iPSCs)are pluripotent stem cells obtained through transduction of specific transcription factors and reprogramming of human and animal somatic cells,Which are similar to embryonic stem cells.The iPSCs possesses characteristics of unlimited proliferation,self-reneWal and multi-differentiation.This arti-cle mainly summarized current research condition,application value and prospects of iPSCs in cardiovascular area, and its defect in application of current stage.

ABSTRACT

AIM To study the activation of choline on M3-R in heart and observe the hemodynamic changes of rat and rabbit. METHODS A cardiac catheter was inserted into the left ventricular cavity via the right carotid artery, then the HR, LVSP, LVEDP, and ±dp/dt were measured using a polygraph system. RESULTS Choline was shown to decrease the hemodynamic assessments, such as HR, +dp/dt, LVSP and LVEDP. while the M3-R antagonist 4-DAMP (4-diphenylacetoxy-N-methylpiperidine-methiodide) showed little effect on these assessments. It was found to reverse the hemodynamic effects of choline. CONCLUSION M3 receptor agonist can produce negative inotropic and chronotropic effects on the heart of rat and rabbit.
