Human sperm created from embryonic stem cells (Update)
Scientists claim to have created human sperm for the first time, in a breakthrough they say could lead to new treatment for male infertility. They then went on to test whether this sperm would function in real life. Older Interviews Interviews Interviews Interviews From Wikipedia, the free encyclopedia. As well as being prohibited by British law, the research team say fertilisation of human eggs and implantation of embryos would hold no scientific merit for them as they want to study the process as a model for research. Nayernia is currently testing whether mouse eggs fertilized with IVD sperm can lead to a healthy animal.
BBC NEWS | Health | 'Lab-made sperm' fertility hope
The Newcastle scientists reported this month that they had produced the sperm in a laboratory and that it could one day help infertile men father children. The feat, which is published in this month's issue of Developmental Cell , gives researchers a potential new tool to study sperm development and could eventually help scientists understand and even treat some kinds of infertility. Retrieved from " https: Late Tuesday, it released the following statement: British Broadcasting Corporation Home. It has long been known that genes on the Y are required to make sperm.
The scientist, who created mice sperm six years ago using similar techniques, said that he used four criteria to determine whether the cells he produced were sperm.

But the scientific journal Nature quoted him as saying that half of the introduction paragraphs were plagiarized from a review in the journal Biology of Reproduction. The sperm was grown in a laboratory in Newcastle from embryonic stem cells. This findings define this novel marker and its effector signaling pathways as key factors in the proliferation and survival of breast cancer stem cells. World Show more World links.
