New Embryology with Focus on Stem cells Biology and their Ethical Issues
Recent advances in the field of embryology/developmental biology and specifically, in stem cell research, have opened up a wide variety of benefits for humanity. While some forms of cloning and stem cell applications were initially prohibited, they have now gained conditional acceptance from many scientists and ethicists.
Ethical issues of stem cell research are still the greatest concern not only among ethicists, but also among scientists, religious scholars, governments and politicians.
In this article, various topics concerning the new embryology, including stem cell biology will be reviewed, and several alternative sources of pluripotent stem cells which have been implicated or suggested recently will be presented. The goal of these new proposals is to avoid embryo destruction, the main objection to embryonic stem cell research. This article also suggests that apart from ethical issues, most of the technology for human embryo-saving alternatives is not yet secure and should not be applied before thorough research in animals and in preclinical research stages has been carried out.
The second part of the article explains the limited resources, technical complexity and unidirectional approach of the research on stem cells, which come mainly from females rather than males, which has advantages and disadvantages.
