Summary:
Scientists have demonstrated for the first time that embryonic stem (ES) cells cultured in the laboratory can produce sperm with the capacity to produce viable offspring. The research, published in the July issue of Developmental Cell, opens many exciting avenues for future studies, including investigation of mechanisms involved in sperm production and development of new treatment strategies for infertility. The results of this study establish that the ES cell derived cell lines can produce functional sperm in the laboratory which can be used to successfully fertilize eggs and support full-term development into embryos and adult mice.
Commentary: Maybe this can lead to improved fertility treatments, but also an ethical means of deriving embryonic stem cells.
