Resumen
[ES]El corazón adulto de mamíferos es un órgano que posee una capacidad de
regeneración muy reducida tras producirse una lesión cardiaca. Recientemente se
ha demostrado que existe una capacidad de regeneración mucho mayor en corazón
postnatal de mamíferos anterior al séptimo día de vida, a partir del cual dicha
capacidad se reduce hasta equipararse a la del adulto. Esto indica la existencia de
unos procesos activos en corazón de mamífero postnatal directamente relacionados
con la regeneración del músculo cardiaco, en la que muy posiblemente sea debido al
efecto de uno o varios genes.
En la actualidad se conoce que los cardiomiocitos diferenciados son los
responsables de regenerar el miocardio en la situación comentada anteriormente,
sin embargo, aunque la regeneración tiene lugar por miocardiocitos, los genes
implicados se desconocen.
Este estudio pretende identificar los genes que pueden estar jugando un
papel importante en la regeneración del músculo cardiaco en etapas postnatales en
un modelo de ratón.
Los resultados obtenidos en este proyecto de investigación proporcionarán las
bases necesarias para el desarrollo de una futura línea de investigación, la cual
tendría como objetivo desarrollar un modelo in vivo para el estudio de la
regeneración cardiaca en corazón adulto. La utilidad de este proyecto se basa en
identificar los genes y mecanismos responsables de la regeneración cardiaca para
estimularlos en un corazón infartado adulto, de modo seguro y eliminando la
posibilidad de rechazo derivada del uso de células exógenas al corazón.
[EN]The adult mammal’s heart is an organ that has very limited capacity of regeneration after cardiac injury occurs. Recently it has been shown that there is a much greater ability in postnatal heart regeneration before the seventh day of life, from which this capacity is reduced to match that of the adult. This indicates us the existence of active processes in postnatal mammalian heart directly related to cardiac muscle regeneration, which is most likely due to the effect of one or more genes. Today it is known that differentiated cardiomyocytes are responsible for myocardial regeneration in the situation discussed above. However the process those results in the regeneration, as well as genes involved in this process are unknown. This study aims to identify genes which may be playing a role in the regeneration of cardiac muscle at postnatal heart. The results obtained in this research project provides the necessary development of a future line of research bases, which would aim to develop an in vivo study of cardiac regeneration in adult heart model. The usefulness of this project is to identify genes and mechanisms responsible for cardiac regeneration to stimulate the infarcted adult heart, securely and eliminating the possibility of rejection due to the implantation of exogenous cells.
