3d ‘bioprinter’ produces bone, muscle, and cartilage
Health Reuters- A new 3D printing method The researchers reported the size of the surviving bone, muscle and cartilage templates when implanted in the animal. \"It has always been a challenge to produce human-scale organizations with 3D printing technology because larger organizations require additional nutrition,\" Dr. Anthony Attara of Winston Wake Forest Medical School Salem in North Carolina told Reuters Health by email. His team has developed what they call a process of \"integrating tissue and organ printing systems\", referred to as ITOP. ITOP produces a network of tiny channels that allow print tissue to be nourished after being implanted in living animals. The researchers made three tissues, bone, cartilage and muscle, and transplanted them into rats and mice. The team reported in the journal Nature Biotechnology that five months after implantation, bone tissue looked similar to normal bone, with complete blood vessels and no dead angle. Human- Under the microscope, the size of the ear implant looks like normal cartilage, the blood vessels supply the external area, and there is no circulation in the internal area ( Like natural cartilage). The fact that there are viable cells in the internal region suggests that they have received adequate nutrition. 3D results The printed muscles are equally impressive. When examined after two weeks of implantation, not only does the implant look like a normal muscle, but the implant also shrinks like an immature muscle and develops during stimulation. \"It is often frustrating for doctors to have patients undergo plastic or metal parts during surgery because they know that the best alternative should be the patient\'s own organization,\" Dr. Atala said. \"The results of this study bring us closer to the reality of using 3D printing to repair defects using the patient\'s own engineering organization. \"We are also using similar strategies to print solid organs,\" he added . \". Dr. Lobat Tayebi, from the School of Dentistry at the University of Marquette, Milwaukee, Wisconsin, also did a bioprinting study, and he told Reuters Health Channel via email, \"bioprinting tissue integrity and robustness ( Supply of blood vessels) Part of the final product. The most admirable part of this study is the serious effort to overcome these problems by introducing integrated organizationsorgan printer (ITOP). This is a big step towards producing powerful bio-repair tissues of any size and shape. \"I believe that while this approach has great difficulties, it can eventually be used to produce reliable and robust tissue for biological printing,\" she said . \". \"Real personalized medicine is developing, especially in the field of tissue regeneration. ” SOURCE: bit.
