Transplantation2

  • Ovarian graft antigens could trigger tumor immunity and extend survival

    Where this hypothesis actsGerm-cell-depleted young ovarian grafts with antigens shared by incipient recipient tumors

    What is proposedTransplant young ovarian somatic tissue that exposes shared tumor antigens

    With whatCell therapy

    HowUse germ-cell-depleted young ovarian grafts; germ-cell depletion is proposed to change antigen accessibility

    Possible resultPossible reduction in lethal cancer incidence and improved survival through tumor-reactive immunity

  • Young ovarian networks may limit systemic injury by rejecting isolated extreme distress signals

    Where this hypothesis actsYoung ovarian grafts depleted of germ cells, with graft viability and recipient conditions controlled

    What is proposedTransplant young ovarian somatic cells with intact adaptive input sensing

    With whatCell therapy

    HowCompare sensing-competent grafts with sensing-disabled grafts and a matched open-loop secretome replay after demonstrating input rejection in a multi-tissue system

    Possible resultPossible protection against disproportionate injury responses, with improved survival and function

Elimination1

  • Clearance of dying ovarian graft cells may prolong life by resolving damaging inflammation

    Where this hypothesis actsYoung donor ovarian grafts depleted of germ cells

    What is proposedInduce controlled apoptosis and clearance of donor cells

    With whatCell therapy

    HowManipulate donor apoptosis and test a matched preparation of apoptotic ovarian somatic cells against ordinary and apoptosis-resistant grafts

    Possible resultPossible reduction in inflammatory mortality and functional deterioration
