Scientists have created human embryos from skin cells, which has been hailed as a breakthrough in the study of infertility, but also raises serious ethical questions.
An international team led by researchers from Monash University in Melbourne has found skin cells in Reprogramming three-dimensional structures that resemble the early stages of human embryos.
Lead researcher Jose Polo said the breakthrough would help research that previously required an embryo made from egg and sperm.
« It will allow us to study the early days of human development without using human embryos and it will allow us to study many cases of infertility and, for example, why many miscarriages occur within the first two weeks of pregnancy, « he said.
Monash Biomedicine Discovery Institute director John Carroll said the breakthrough came after years of experiment Entierens come.
« They had this kind of Eureka moment when they looked at the microscope and discovered that they had formed these little embryo-like structures, » said Professor Carroll.
« Worldwide this is going to be one be big news in the whole research world. There is great interest in making this breakthrough. «
Professor Carroll acknowledged that science raises some important ethical questions, but said it is important to emphasize that the embryos cannot be considered viable.
« It’s a question that needs to be investigated, but this is really an in vitro model. It doesn’t really develop beyond day 10 or 11 of normal lab development, « he said.
» I think it gives us that path to medical advancement, and you know there are strong, strong globally applied ethical frameworks and regulations, laws that really prevent anything from going too far with human material. «
