Therapeutic cloning by xenotransplanted oocytes, supplemented with species specific reprogramming factors
University of Veterinary and Animal Sciences, Lahore, Pakistan.Medical Hypotheses (Impact Factor: 1.07). 04/2011; 76(4):527-9. DOI: 10.1016/j.mehy.2010.12.008
For therapeutic medication, a lot of work has been done regarding human embryonic stem (ES) cell lines derivation, but immunorejection is a major dilemma of this cell based therapy. Since long time, derivation of patient matched stem cells have been hoped to overcome this problem. Oocytes after nuclear transfer are the most reliable source for patient matched ES cells derivation, for therapeutic use. In humans, utilization of oocytes for stem cell research raises sensitive logistical and ethical questions; primarily surrounding participation of women as oocyte donors. It has been claimed that therapeutic cloning would lead to commercial exploitation of poor women. On the other hand, the therapeutic promise of embryonic stem cell is so huge that there is a strong incentive to find some alternate sources of human oocytes. Here we propose to utilize the cross species oocytes supplemented with human ES cellular extracts to establish patient specific ES cell lines.
