L’administration de cellules souches adultes est une option thérapeutique d’intérêt pour les patients présentant une artériopathie des membres inférieurs ou un infarctus du myocarde. L’efficacité de l’injection de différents types de cellules souches/progénitrices adultes autologues dérivées de la moelle osseuse, du sang périphérique ou encore de tissus a été évaluée dans des modèles expérimentaux. Ces cellules, notamment celles d’origine médullaire ou adipocytaire, font l’objet d’essais cliniques. Cette revue synthétise les principaux mécanismes moléculaires et cellulaires sous-tendant l’action des cellules souches/progénitrices adultes sur le compartiment vasculaire et propose quelques approches pour améliorer leur efficacité thérapeutique chez les patients ischémiques.
Abstract
The application of endothelial progenitor cells (EPC) cell-based therapy for regenerative medicine constitutes a promising therapeutic avenue for the treatment of cardiovascular diseases. Based on experimental studies demonstrating that bone marrow-, blood- or tissue-derived stem/progenitor cells improve the functional recovery after ischemia, clinical trials were initiated to address this new therapeutic concept. Although autolougous cell therapy was shown to improve perfusion and function of ischemic tissues, a number of issues remain to be adressed. The nature of the mobilizing, migratory and homing signals, and the mechanisms of action need to be identified and further defined. In addition, strategies to enhance homing, survival and therapeutic potential of EPC need to be developped to improve therapeutic effect and counteract EPC dysfunction in aged patients with cardiovascular risk factors. The present review article will discuss the mechanisms of action of different types of adult stem cells and several approaches to improve their therapeutic efficiency.
