Resumen

PEREZ MILLAN, María Inés  y  LORENTI, Alicia. Stem cells and cardiac regeneration. Medicina (B. Aires) [online]. 2006, vol.66, n.6, pp. 574-582. ISSN 1669-9106.

Stem cells are defined by virtue of their functional attributes: absence of  tissue specific differentitated markers, capable of proliferation, able to self-maintain  the population, able to produce a large number of differentiated, functional progeny, able to regenerate the tissue after injury. Cell therapy is an alternative for the treatment of several diseases, like cardiac diseases (cell cardiomyoplasty). A variety of stem cells could be used for cardiac repair: from cardiac and extracardiac sources. Each cell type has its own profile of advantages, limitations, and practicability issues in specific clinical settings. Differentiation of bone marrow stem cells to cardiomyocyte-like cells have been observed under different culture conditions. The presence of resident cardiac stem cell population capable of differentiation into cardiomyocyte or vascular lineage suggests that these cells could be used for cardiac tissue repair, and represent a great promise for clinical application. Stem cells mobilization by cytokines may also offer a strategy for cardiac regeneration.  The use of stem cells (embryonic and adult) may hold the key to replacing cells lost in many devastating diseases. This potential benefit is a major focus for stem cell research.
