About Zeng Fanyi
Zeng Fanyi was born in Shanghai, China, in 1968. Her family originally came from Shunde in Guangdong province.
Her father, Zeng Yitao, is also a well-known scientist who studies genetics (how traits are passed down from parents to children). Both Zeng Fanyi and her father learned from Tan Jiazhen, who helped start the study of modern genetics in China.
Zeng Fanyi's Education and Career
Zeng Fanyi went to the University of California, San Diego (UCSD) for her first degree in science. Later, she earned two advanced degrees, an M.D. (Doctor of Medicine) and a Ph.D., from the University of Pennsylvania. She also did more research there after finishing her studies.
In October 2007, Zeng Fanyi joined the Shanghai Jiao Tong University School of Medicine. Today, she is the vice-president of the Shanghai Institute of Medical Genetics at SJTU. Her father, Zeng Yitao, is the director of this institute. Zeng Fanyi is also the vice-president of the Shanghai Stem Cell Institute.
Zeng Fanyi's Research Discoveries
Zeng Fanyi's main research focuses on medical genetics and developmental biology. This means she studies how living things grow and develop, and how genetic information affects health.
Creating a Mammal from Stem Cells
In July 2009, Zeng Fanyi and her team made a very important discovery. They published their findings in the science magazine Nature. They showed for the first time that a whole mammalian body could be grown from special cells called induced pluripotent stem cells (iPSCs).
Here's how they did it:
- They used mouse embryos.
- They created iPSCs from these embryos. These iPSCs are like "master cells" that can turn into any type of cell in the body.
- They then made special embryos called "tetraploid" embryos. They did this by joining two very early-stage fertilized embryos together.
- They put these special embryos into female mice.
- Some of these embryos grew into full, healthy mice!
- Even more amazing, twelve of these mice grew up and had their own offspring (babies). These baby mice were completely healthy and normal.
This research was a huge step forward in understanding how cells can be used to grow new tissues or even whole organisms.
