Introduction: The only thing you can do upon failure of some organs is to transplant them from the donor, usually to be a dead person, to the person facing this disorder. Kidney transplantation is a very popular transplantation among the world nowadays which is generally accepted as the best solution for some renal diseases even though there are some other renal replacement therapies. There are also many other common surgeries as those which are done for heart and liver transplantations. The transplantation surgery involves removing the old organ from the deceased person’s body and this step should be done under certain legal conditions including the definition of death. However, a kidney may be donated by a living person with a good health…show more content…
During transplant surgery, when a person receives an organ from another individual the body will recognize this organ as a non-self and starts to work to destroy by secreting white blood cells (T-Lymphocytes) and there are three types of rejection. 1-Hyperacute rejection is due to completely unmatched antigens and takes place few minutes or hours after the transplant. This type of rejection may lead to the death of the individual and it should be immediately removed. This type of rejection mainly occur in xenogeneic grafts and it is due to pre-existing antibodies directed to components of the graft and this type of rejection never become vascularised. 2- Acute rejection occurs between the first weeks to three months after transplantation. Acute rejection happens in some amount in all recipients. This rejection involves cell-mediated (mainly) and antibody-mediated immunity. 3- Chronic rejection may occur after many years. The new organs/tissues are slowly damaged by the body’s immune system (mainly in lungs…show more content…
The shortage of human organs available was the cause of inventing this printer. In 2009 a study was conducted that shows 154,324 patients in the United States are in need for organs; however, 18% of them (27,996 individual) received organ transplant while 8,863 patient died per day due to this shortage(25% per day). 3D printing is the usage of a 3D bioprinter to produce artificial organs. Recent studies shows that 3D printing is used to create ears, stem cells, windpipes, bones, a jaw bone, cell cultures, exoskeletons, blood vessels, tissues, vascular networks, and organs, and also drug delivery devices and novel dosage forms. The current medical uses of 3D printing can be grouped into several categories: implants, tissue and organ fabrication; and anatomical models; creating prosthetics, and pharmaceutical research concerning drug delivery, dosage forms and
