A patient’s immune system can often react badly to bone marrow transplants. Mesenchymal stromal cells (MSCs) may help, but they too can be cleared out by immune cells. Now, a Harvard team has shown that coating MSCs in a thin hydrogel can protect them, making bone marrow transplants more successful.

A study has revealed killer immune cells have been found to collect in parts of the brain where new nerve cells are generated. This proliferation seems to naturally increase as a brain ages and the researchers hypothesize this may be a mechanism that underpins general age-related cognitive decline.

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 does away with the need for.

In recent years scientists have been able to correct genetic diseases by removing stem cells, editing their genomes and implanting them back into patients, but that adds complications. Now new research led by Harvard scientists has successfully edited the genes of stem cells while still in the body.

Radiotherapy is effective for killing cancer, but it harms healthy cells at the same time. Now researchers have found that boosting levels of a certain protein can protect against radiation damage, which could help cancer patients, victims of nuclear disasters, and future space travellers.

After a heart attack this vital organ remains damaged, which can eventually lead to heart failure and death. Now, researchers have managed to use placental stem cells to regenerate heart cells in mice, which could lead to groundbreaking new treatments for heart attack victims.

Unfortunately stem cells lack some of the self-defense mechanisms that other cells have, leaving them open to attack from viruses and other threats. Now, researchers from the University of Edinburgh may have found a way to switch this mechanism back on, making stem cell treatments more effective.

An incredible new study has for the first time found a way to transform skin cells into all three of the stem cell types that make up an early-stage embryo. This extraordinary discovery points a way toward creating an embryo without the need for an egg or sperm.

For many years now, scientists have been seeking methods of helping to heal chronic wounds such as those suffered by diabetics. One of the latest possible techniques involves re-engineering the membranes of stem cells, so that those cells essentially get welded together.

This installment of our Revolutions series brings you up to date with the ground-breaking new discoveries made around the regenerative possibilities of induced pluripotent stem cells, which can theoretically be coaxed into any kind of cell in the human body.
