She focuses on the cloning human embryonic stem cells using animal eggs. While adult stem cells are readily available for researchers, embryonic stem cells are not because of a scarcity of eggs.
In late 2003, Sheng announced in Cell Research, a peer-reviewed Chinese journal, that she had fused human skin cells with rabbit eggs to produce early stage embryos.
While some groups opposed to stem-cell research condemned her work for destroying embryos that they said were human in identity, other scientists expressed excitement that the stem cells her laboratory grew could be used to grow tissue for transplants.
Sheng said that while she's happy to pursue her projects in China, she still thinks the scientific talent and environment in the United States is the best in the world. In China, she said, she often feels lonely. China is "lacking a critical group of scientists in your field who understand your ideas," Sheng said.
"China has been learning, and will continue to learn, from the United States."
