Surveillance Gaps: How Cancer Arises

Extended pluripotent stem cells from mice can self-organize to form blastocyst-like structures called blastoids that enable a closer look at early mammalian development.

The lab animals had more natural microbiomes seeded by wild mice, unlike conventional models that are kept in sterile conditions.

Machine learning could be the key to reducing the use of animals in experiments.

By zooming in on a developing mouse heart, scientists are studying whether defects in vasculature contribute to a thin muscle wall.

T cells modified to target disease-contributing B cells improved survival in two mouse models of the autoimmune disease.

Genetic mutations create lab mice with unusually long and short tails.

Researchers use a CRISPR-Cas9 strategy to expand a desired trait from 50 percent of mouse pups to about 72 percent.
