Human epidermis was grown from stem cells

In laboratories of King’s College in London it was possible to grow epidermis with the use of stem cells. The epidermis is structurally and functionally similar to native one in humans. It has protective functions and permeability, thus it can be a natural barrier. The research was published in Stem Cell Reports in April 2014. Read full text »

Lung transplantation using Organ Care System

Instead of a cooler, Gary Cunningham’s new set of lungs arrived at UPMC Presbyterian in a high-tech box on wheels. The small machine kept the donor lungs functioning and “breathing” outside the body with a constant supply of blood and nutrients. The machine, made by Massachusetts-based TransMedics, allows the lungs to remain at a normal body temperature [1, 4]. It was one of the first case of using mechanical perfusion in normothermia for lung storage before transplanting. There are similar researches in kidney and liver transplantation. Read full text »

Organs from the printer

Modern sciences – such as medicine and technology are developing at a very fast pace. The result of this development is the emergence of ever new devices, tools and techniques. The purpose of these inventions is to support not only the work of scientists and experimenters, but also practitioners. This development is so fast that things which a few years ago seemed like a pure abstraction are common now, and in some cases even commonly used in clinical practice. One of the latest techniques are 3D bioprinters.

Renal transplantation – fasting protects the kidney grafts

We are all very much accustomed to the idea that good nutrition is essential for postoperative success. However, studies show that in case of organ transplantation it seems to be the other way round. Short term dietary restriction or fasting protects the transplanted kidney from failure. It seems that the consequences of ischemia/reperfusion (I/R) injury can be diminished. As a mechanism of this reaction is unclear, recent studies show that glucose supplementation does not interfere with the fasting-induced renal protection. Read full text »

Transplant of human legs – tears of happiness after a surgery in Spain and new opportunities for people without prosthesis

Transplantation medicine has made another step forward! This time a person, who had been doomed for a wheelchair, was given a chance to walk on new legs. The simultaneous transplantation of two legs was conducted by dr Pedro Cavadas from Spain. Read full text »
