23 Jul Construction method for tissue engineering liver unit and tissue engineering liver unit
Abstract
The present invention discloses one kind of tissue engineering liver unit and its construction process. The tissue engineering liver unit containing vascular endothelial cell and liver cell is prepared through in vitro pre-introducing liver cell and vascular endothelial cell with mesenchyme stem cell, separate combining with albumen glue containing induction factor and filling to the inner wall and outer wall of one tubular rack, coating with one outer enclosure to form a cell complex, and further culturing the cell complex in culture liquid. The present invention obtains great amount of seed cells for liver tissue engineering with mesenchyme stem cell and combines the seed cells with proper bioactive material to obtain auxiliary liver function structure unit. The tissue engineering liver unit may be transplanted to body of hepatic failure patient to compensate and replace liver function. The present invention provides one new treating way.
