| Outline of Final Research Achievements |
We have executed a basic research for regenerative therapy utilizing mouse embryonal stem cell aimed at hypothalamic dysfunctions caused by brain neoplasms. First, we have developed a novel method to purify hypothalamic precursors. We have identified surface antigens on immature cells, which were removed by antibody-conjugated beads. This purification method doubled the efficacy and viability of the hypothalamic precursor cells. To improve the micro-circumstance of the grafted cells, VEGF, ROCK inhibitors and matrigel were utilized in the cell-transplantation procedure, which prolonged the grafted neurons more than a month. However, these regenerative therapies on the disease-model mice did not reach the therapeutic goals. Further research would be required to achieve the therapeutic effects.
