In one group, the researchers also injected peptide-11.

To give an animal a prion disease, researchers must inject it with the ground-up tissue from the brains of animals that were ill.

The researchers then injected some of these artificially made islets into diabetic mice.

Rather than severing the cords, the Swiss researchers partly cut them and then injected the animals with two substances.

The researchers will then inject the T-cells back into the patient through a simple blood transfusion.

But in the new experiment, researchers will simply inject DNA right into the patient's tumor.

In the study, the researchers injected bicarbonate or an innocuous saline solution into patients who had recently suffered heart attacks.

At the injured site, the researchers immediately injected ensheathing cells that had been gathered from rats' brains and grown in culture.

The researchers injected the gene into single-cell mouse embryos.

In the new approach, researchers will inject genetically altered mouse skin cells into a patient's brain tumor.
