Abstract:
The invention relates to the technical filed of tissue engineering and 3D printing, particularly relates to an artificial tissue progenitor and a method for preparing the same. In particular, the invention relates to an artificial tissue progenitor comprising a solid support and a plurality of microcapsules, wherein at least one microcapsule is attached to the solid support, and the microcapsule comprises a cell and a biocompatible material encapsulating the cell, to a method for preparing the artificial tissue progenitor, to a kit and a package useful for preparing the artificial tissue progenitor, to an artificial tissue obtained by culturing the artificial tissue progenitor, such as an artificial lumen, to a lumen implant or a lumen model containing the artificial tissue progenitor or the artificial lumen, to use of the artificial tissue progenitor in the manufacture of an artificial tissue, a lumen implant or a lumen model, and to use of the artificial tissue in the manufacture of a lumen implant or lumen model.

Claim (Index 14):
The method of  claim 10 , comprising the following steps:\n (1) providing a bio-ink in a first ink cartridge of a 3D bio-printer, wherein the bio-ink comprises a carrier and one or more microcapsules, and providing an adhesive in a second ink cartridge of the 3D bio-printer; (2) printing the bio-ink on a predetermined area of an elastic film which is covered on the out wall of a rotary rod of the 3D bio-printer via a first printer head connected to the first ink cartridge of the 3D bio-printer, and obtaining a tubular biological construct; (3) printing the adhesive on the tubular biological construct obtained in step (2) via a second printer head connected to the second ink cartridge of the 3D bio-printer, and obtaining an adhesive layer; (4) sheathing a tubular solid support on the outer surface of the tubular biological construct with the adhesive layer obtained in step (3); (5) expanding the elastic film, thus attaching the tubular biological construct with the adhesive layer to the inner wall of the tubular solid support, immobilizing the biological construct with the solid support by adhesive effect, and obtaining the artificial tissue progenitor; optionally, the method further comprises separating the tubular biological construct from the elastic film.
