Because these patients don't die as quickly as they used to, and as kidney failure increases with the rising age and prevalence of high blood pressure and diabetes in
Organ printing are some organ-specific structural elements that must be addressed for successful creation of a transplantable printed organ. The transfer of nutrients and oxygen to cells throughout a printed organ is essential for its function. In very small or thin tissues of less than a millimeter in thickness, cells can receive nutrients through diffusion. However, larger organs require the transportation of nutrients to cells deeper inside the tissue, which requires that the tissue be vascularized, and thus able to receive blood for the exchange of cargo like oxygen and cell wastes. Early organ printing techniques created solid tissues that were unable
