23 Jul Artificial organoid and building method thereof
Abstract
The invention relates to the technical field of tissue and organ engineering and discloses an artificial organoid and a building method thereof. A kidney is included, and comprises cortex, a renal pelvis and medulla; an artery, a vein and a ureter are arranged on one side of the kidney; the outer layer of the kidney is wrapped by a tunic; and kidney vessels are arranged in the kidney. According tothe building method of the artificial organoid, the organoid is designed completely according to the human body organ inner structure, living cells and biological ink are printed at the same time, one-time forming is achieved, high similarity with a human body original organ is guaranteed, and the original organ can be replaced to execute the functions needed by a human body; the hardness, the toughness and the functionality of healthy tissue and organs reappear while the mechanical stability is guaranteed; a selected material has extremely high biological safety and good biological compatibility, sterile printing is performed in the whole process, and it can be directly used for animal or human body transplantation to replace lesion tissue and organs, restore wound tissue and organs or fill up defective tissue and organs.
