| Outline of Final Research Achievements |
Glial cell line-derived neurotrophic factor (GDNF) secreting capsule secreted GDNF and VEGF for more than 12 months, and the control capsule secreted only VEGF persistently. When odontblast-like cells（KN3 cells） were co-cultured with the maintenance medium of both capsules under long-term starvation conditions, the number of living cells were significantly greater than without capsules and had ALP activity performance. Also, inhibition of VEGF in maintenance medium secreted from both capsules resulted in a decrease in cell survival number only in the control capsule stimulation group.
The present study provide the first evidence that the sustained delivery of GDNF from encapsulated, genetically-modified cells can enhance and prolong the survival of KN3 cells under in vitro long-term starvation conditions. And this study was accepted the paper by Journal of Regenerative Medicine.
