Although the goal of 3D printing human organs is still far away, this dream will be closer to reality. In Australia, the Sydney-based Heart Research Institute (HRI) has developed a bioprinter that prints human cells that can be used to repair damaged heart tissue. The effects of the study are also amazing. These heart cells can beat like a real heart.
Dr. Carmine Gentile, a scientist at HRI, said that patients only need to provide their epidermal cells to the medical staff, use them to generate stem cells, and then further generate heart cells. Using this printer, doctors can print the specific heart cells needed by the patient and then create tissue that can be implanted into the heart to repair damaged organs.
This method is beneficial to patients suffering from heart disease, especially when traditional treatments do not work. Typical cardiac treatment procedures, including angioplasty, in which the balloon is puffed to enlarge the blocked coronary artery, as well as reperfusion therapy, including implanting the stent and performing a large number of drugs. In the process, 3D printing organizations can provide much-needed alternatives.
Gemma Figtree, a cardiologist and associate professor at Colin College, explains that by replacing the necrotic heart muscle with an effective "patch", they can greatly solve their shortness of breath and improve their quality of life. “In Australia alone, 350,000 people are suffering from heart disease, and 24 people die of heart disease every day, so this breakthrough in 3D printing makes a lot of sense.â€
In addition to creating implantable heart cells, 3D bioprinters can also create specific organs for drug testing. That is to say, a mini heart organ can be created from the patient's own cells, and the effect is first tested on the mini heart organ before the patient is administered the drug. Dr. Gentile also called it an amazing discovery, because it allows us to discover the side effects of drugs in patients in a short time.
Of course, this technology will not be immediately introduced to hospitals across Australia, and HRI researchers believe that this technology will not be used for patient treatment in the next five to ten years.
Although 3D bioprinting can be implanted into human tissue, it is still in the laboratory stage, but 3D printing has begun to be applied to some cardiac surgery practices.
According to reports, Hong Kong doctors have used 3D printed simulated organs to prepare for surgery and improve the success rate of surgery. The Chinese University of Hong Kong and the University of Hong Kong have jointly developed a technology to create a highly simulated complex cardiac structure 3D silica software model through 3D reconstruction of data collected by patient esophageal ultrasound imaging to assist in preoperative planning and personal development for patients. Interventional treatment options.
