Bioengineers have paved the way for the first 3D-printed replacement organs for human organs with a breakthrough technique for bioprinting tissue. With this breakthrough in tissue biopsy technology, they have paved the way for the development of 3D - printable, human - 3D printed organs. With this breakthrough in this technique, we can create biosynthetic, biological and biodegradable tissue for humans.
Viable tissues and organs for patients have been grown using 3D printing and electrospinning using a new bioprinting technique for human organs.
The aim is to use 3D printers that can expand the process so that tissues and organs do not have to be tailored. Above all, you cannot just glue an organ from a 3D printer to a patient. The main difference between a human organ and a 2D printed organ is that 3D printed organs can use the patient's cells as the building blocks of a new organ, drastically reducing the likelihood that the tissue will be rejected. This group is focused on printing blood vessels, rather than trying to 3D print cells for an entire organ.
When printing human tissues and organs, you have to make sure that the cells survive, and the protocol is designed to expand those cells. Before a particular organ is printed, a tissue sample is taken, the organ has specialized cells and its function is examined in a final test.
You have to place the cells in the right place in a matrix that supports their growth, and you might be able to replicate the organ or something that might work like that. 3D printing already implants differentiated model cells into the human body, waiting for the cells to fuse with the existing cells and replace the defective organ.
Researchers have already managed to replicate the structure of the organ they want to copy with 3D printers, and while this example highlights the great development that is able to print a functioning tissue with precision, it will take some time before it is possible to bioprint an entire transplantable organ. At this stage in the development of the organ printing technology, it is safe to say that we must first try to design a simplified version, he explained. This will allow doctors to print a 3D model that can beg as close to reality as the technology can get.
Most experts, including Atala of Wake Forest, don't think we'll see organs 3D printed in years, if not decades. But technology is advancing so fast that it could become a reality faster than we think. If it can be perfected and expanded, the risk of a long wait for transplants could end. Long-term 3D bioprint has the potential to transform the game and provide an alternative source of organs without the need for living or deceased human organs, as human organs are printed on demand.
Artificial organs printed with biotink from the patient's cells would eliminate the need for transplants by eliminating the need for organ donors and reducing the risk of tissue rejection. The potential is that the organ is so small in this way that it eventually becomes part of the patient's body and doesn't need to be replaced, "Miller said.
Although the pancreas would not yet be able to completely replace an organ, Lewis says this revolutionary development could prove to be the world's first 3D-printed human organ. However, Lewis said it will take years to use rapid techniques to print fully functional organs that can be safely used in humans, and even then it is still a long way from a full transplant.
Although Bioprint is expected to help patients who currently need organ transplants, many are concerned that there is currently no clear timetable for when biopsied tissue and organs will be available. Consider recent advances in 3D - printed organs like the world's first 2D-printed heart - and there was even a time when patients who needed organ donation had organs printed organic from their own cells, rather than sitting on a waiting list.
However, biotech company BIOLIFE4D wants to print a human heart by 2019, and the bioprint firm is also considering a bid. Organovo is currently trying to deliver tissue - from 3D printers - to patients by next year. The Medical University of Vienna has 3D printed human placenta this year, so 3D printed organs could soon be a much-needed solution for patients in need of organ transplants.
By using donated tissue and stem cells, Organovo is developing the world's first 3D-printed human organ system for human transplantation using a fully automated bioreactor system. Information and signals are generated using the patient's cells and anatomy and can be done with the company's fully automated, fast and fully functional Bioprint technology. The ultimate goal is to replicate a functioning tissue - an organ that can then be transplanted to another human being.
