In Science this week, a group of Chinese investigators reported on the discovery of a cocktail of small molecules that can induce somatic cells to become pluripotent stem cells. The researchers used a combination of seven drugs to reprogram about 0.2 percent of mouse somatic cells into pluripotent cells that resemble embryonic stem cells. The chemical reprogramming strategy offers a new route to generate functional desirable cell types for clinical applications.
