  3. 3. Health Care problem<br />Aim: reduce the number of pts with symptomatic cardiac failure<br />Unravelling the mechanisms behind the beneficial effects of stem cell therapy will allow us to improve the cardiac regenerative capacity of the human heart. <br />
  4. 4. Research questions<br />Whatroles do neovascularization, paracrine factors, microRNAsplay in cardiacregenerationandrepair? <br />Why do patients post-MI or withchronic angina respondpositivelyto stem celltransplantationandothers do not?<br />Do cardiovascular risk factors (Gender, smoking, diabetes, high bloodpressure, high cholesterol DM) have an impact on stem cellbehaviour or host response?<br />Do endogenousprogenitorscontributetocardiacrepair in response to stem celltransplantation?<br />Can we boost endogenousregenerativecapacity of the heart?<br />

  14. 14. Focus areas Netherlands Heart Foundation<br />Individualvariation: <br /> G,A,M<br /> Hartfalen, Hartstilstand, GENDER, Aangeboren Hartafwijkingen <br />Females respond differently to heart attacks than males. In addition, the electrophysiological responses of freshly isolated human primary cardiomyocytes differ in males and females. We will investigate the responses of human stem cell derived cardiomyocytes in culture to male and female hormones. Inclusion females preclinical and clinical.<br />
