Stem cells are received from unfertilized ovules of a human being
Russian and American scientists managed to receive the cells similar on their properties to stem cells of embryos, from unfertilized ovules of a human being.
Researchers from the Moscow Center of obstetrics, gynecology and perinatology of the Russian Academy of Medical Science and corporations Lifeline Cell Technology managed to bring up 6 lines of stem cells from blastocysts, formed as a result of donor ovules division, unfertilized by spermatozoons. The received cells possess morphological and biochemical properties of stem cells of a usual human embryos and a normal double set of chromosomes (23 pairs).
Analysis of stem cells’ DNA has confirmed their tissue compatibility with an organism of women - donors. It means that it is possible to implant such cells to the parent ovules’ donor in the therapeutic purposes without risk of graft rejection. Stem cells received from the usual embryos have unique genotype and consequently can be rejected by the immune system of the patient.
Earlier scientists managed to receive stem cells from mice’s and monkeys’ unfertilized ovules, however similar experiments with human tissues until recently have no results.
