Scientists have demonstrated a new way to reprogram adult tissue to become cells as versatile as embryonic stem cells—without the addition of extra genes that could increase the risk of dangerous mutations or cancer.
Researchers have been striving to achieve this since 2006, when the creation of so-called induced pluripotent (iPS) cells was first reported. Previously, they had managed to reduce the number of genes needed using small-molecule chemical compounds, but those attempts always required at least one gene.
Now, writing in Science, researchers report success in creating iPS cells using chemical compounds only—what they call CiPS cells.
