| Outline of Final Research Achievements |
We established the original culture protocol to reproducively create the hepatic spheroids which contained human mature hepatocytes, HUVEC, BM-MSC. These spheroids showed high function and could be manipulate stablely by the 3D bioprinter. We developed the large device to fix the spherooids and improved the cerculating culture system to construct effectively a larger hepatic tissue using the 3D bioprinter. Following these works, we established the methods to fabricate the hepatic tissue several times as large as previous one. We cultured the hepatic tissues which contained mature hepatocytes,HUVECs and BM-MSC for 1 month. As a result, the tissue showed vascular formation and biliaty constructs by the histlogical examination.
