Chemically induced pluripotent stem cells

Scientists have been able to reprogram the mature human stem cells, using only the chemical compound (without genetic manipulation).

A new method of obtaining cells are as versatile as embryonic stem cells, reduces the risk of developing cancer or of mutations that can occur as a result of stem cell therapies, "reprogrammed" with the introduction of additional genes.

Since then, in 2006, it was announced the discovery of induced pluripotent stem cells ( iPSCs ), scientists have sought to reduce the number of additional genes required for such cells. But it is always required at least one encoding a protein Oct-4 .
