Abstract

The heart which has limited renewal and regenerative capacity is a prime target for cellular therapy. Stem cell transplantation has emerged as a promising therapeutic strategy to improve healing of the ischemic heart, repopulate the injured myocardium, and restore cardiac function. However, clinical usefulness is impacted by the quality and quantity of delivered cells, the suboptimal manipulations prior to transplantation, and the general poor viability of the cells transferred particularly to an ischemic microenvironment. Focus is now on developing new ways to enhance stem cell renewal and survival capacity before transplant. This can be done by physical, chemical, pharmacological, or genetic manipulation of cells followed by accurate evaluation of conditioning methods by validated tests.This chapter covers the proper handling of mesenchymal stem cells (human and rat lines) and methodologies to evaluate efficacy and the translational potential of conditioning methods. Specifically, we will cover stem cell culture methods, preconditioning protocols, viability assessment in hypoxic and oxidative challenges as encountered in an ischemic microenvironment, and the proliferative capacity of cells.
