Discovery of more efficient way to create induced Pluripotent Stem (iPS) cells

A Boston University School of Medicine-led research team has discovered a more efficient way to create induced Pluripotent Stem (iPS) cells, derived from mouse fibroblasts, by using a single virus vector instead of multiple viruses in the reprogramming process.

Metadherin gene linked to metastasis of breast cancer

A team of researchers at Princeton University and The Cancer Institute of New Jersey has identified a long-sought gene that is fatefully switched on in 30 to 40 percent of all breast cancer patients, spreading the disease, resisting traditional chemotherapies and eventually leading to death.
