3.   His idea was to inject a mouse with a powerful antigen and extract the antibody-producing white blood cells from its spleen.

4.   In separate studies, researchers from Amgen Inc. and Hoffmann-La Roche Inc. injected mice with a protein designed to correct a defective obesity gene.

5.   Newborn brown mice were injected with spleen and bone marrow cells, rich in lymphocytes, from genetically unrelated white mice.

6.   The mice were then injected with large amounts of live HIV, the virus that causes AIDS.

7.   The probes were developed by first injecting mice with billions of viruses and then determining which handful of viruses might target a specific organ or tissue.

8.   Then, they injected mice with that amount of leptin.

9.   Three teams of researchers found that by injecting ob mice with leptin, they not only ate less and slimmed down, but burned calories faster than before.

10.   When the mice were injected with abnormal mouse prions, the infection spread inside muscle, Legname said, but not just any muscle.
