Thus, the obtained results were concluded as follows

1. There is no change in ventricular wall thickness due to chronic hypoxia at both stages of incubation.

2. There is no cardiomyocyte hypertrophy in both 15 and 19 day old chicken embryos due to chronic hypoxia

3. There are no bi-nucleated cells due to hypoxia during the last stage of incubation

I would like to thank my supervisor  Dr. Jordi Altimiras., Ph.D for having provided me with such a wonderful opportunity to work on this study in his laboratory.
