Scientists in the USA have discovered a new way of obtaining embryonic stem cells that avoids contamination by other types of cells and reduces the numbers of embryos needed to create embryonic stem cell lines. Dr Takumi Takeuchi told the 21st annual conference of the European Society of Human Reproduction and Embryology today (Monday 20 June) that if he and his colleagues could replicate the research, which had been carried out in mice, in humans, it would make it easier to collect embryonic stem cells (ESCs) and could make it possible to establish ESC banks. This would enable researchers to have easy access to ESCs to develop better treatments for patients suffering from a range of diseases, as well as for research on fertility.
