Coating cells in hydrogel help protect implanted tissue from the immune system

Bone marrow transplants are a common treatment for certain conditions related to the blood, but the patient’s immune system can often react badly to the foreign cells and attack them. Mesenchymal stromal cells (MSCs) may help, but they too ca… Continue reading Coating cells in hydrogel help protect implanted tissue from the immune system

Hydrogel uses sunlight to harvest fresh water from the sea

In many arid coastal regions, a great quantity of valuable fresh water is lost into the atmosphere every day, as it evaporates from the surface of the ocean. This situation prompted scientists to create a new hydrogel that’s highly effective … Continue reading Hydrogel uses sunlight to harvest fresh water from the sea

Drugs laced with artificial DNA release ingredients in sequence

Researchers at the Technical University of Munich (TUM) have demonstrated a prototype of a drug that can release three active ingredients, at different times in sequence. The key to this unusual and useful ointment is artificial DNA, which br… Continue reading Drugs laced with artificial DNA release ingredients in sequence

Scientists 3D-print biological tissue without using scaffolds

Although it may be hard to believe that there is already an “established” method of doing something such as 3D-printing biological tissue, there does indeed seem to be one. It utilizes microscale scaffolds – which a newly-developed technique … Continue reading Scientists 3D-print biological tissue without using scaffolds
