Producing human tissue in space

10.03.2020

On 6 March at 11:50 PM EST, the International Space Station resupply mission Space X CRS-20 took off from Cape Canaveral (USA). On board: 250 test tubes from the University of Zurich containing adult human stem cells. These stem cells will develop into bone, cartilage and other organs during the month-long stay in space.

3D printing of tissue-like vascular structures

06.03.2020

In a new study published today in Nature Communications, led by Professor Alvaro Mata at the University of Nottingham and Queen Mary University London, researchers have developed a way to 3D print graphene oxide with a protein which can organise into tubular structures that replicate some properties of vascular tissue.

Regenerative medicine: creating a new body?

03.02.2020

Regenerative medicine aims to repair the human body after injuries, accidents or major cancer surgery. Unfortunately, we are still not at a stage where this process can achieve optimal results for every conceivable situation. Having said that, various new methods are on the cusp of breakthrough.

Regenerative medicine: helps the body healing

03.02.2020

Severe wounds heal slowly and leave scars. This is why we have been using regenerative therapies for some time now to accelerate and improve healing. They also help to avoid permanent damage. Still, complex applications like replacing organs or limbs will rather remain vision than become reality for a long time.

rhCollagen: genetically engineered building block for regenerative medicine

03.02.2020

Collagen is the stuff that holds our bodies together and that houses our cells. In regenerative medicine, it is also the stuff that can be applied to wounds to support healing. However, collagen from animal or human sources has some drawbacks for today’s medicine. This is where rhCollagen from the Israeli company CollPlant comes into play.

3D printing of finer, more complex microfluidic networks

31.01.2020

First introduced in the 1980s, stereolithography (SL) is an additive manufacturing process that prints 3D objects by the selective curing of liquid polymer resin using an ultra-violet (UV) light source in a layer-by-layer fashion. The polymer employed undergoes a photochemical reaction which turns it from liquid to solid when exposed to UV illumination.

Endoprosthetic surgery: modern and traditional approaches

01.01.2020

Surgery is required if you need an artificial joint. Patients and doctors must select the type of surgery that’s best suited and choose between robot-assisted, traditional or minimally invasive surgical approaches. Post-operative risks should be kept to a minimum, while benefits should outweigh any possible complications.

Tissue engineering: how to grow a bypass

23.04.2018

A bypass is a complicated structure. It is either made of synthetic materials that can cause blood clots and infections or created by using the patient’s veins. However, the latter often does not yield adequate material. A newly developed bioreactor could solve this problem in the future. It is designed to tissue engineer vascular grafts by using the body’s own material.
