A stem cell injection bound to create a stir is about to take place. For the first time ever the Food and Drug Administration (FDA) (the United States government agency regulating scientific research) has authorized a company to transfer embryonic stem cells to patients paralyzed by spinal trauma. It will be the first procedure of its kind after newly inaugurated President Barack Obama promised to remove limits on financing for embryonic stem cell research imposed by George Bush in 2001.
The details of the initiative are beginning to take form, explained Thomas Okarma,
Shelley Brown was pointing toward a life of cutting-edge stem cell research. Then one day in 2010, she says, she encountered the divine.
“Something was moving, and I thought I must have hit the petri dish by accident,” said Brown, who had been trying to direct a set of stem cells toward bone cells during her Ph.D. work in biomedical engineering at the University of Michigan. “When I looked closer under the microscope, I realized the cells were beating. They had spontaneously differentiated into electrically coupled, beating heart cells. That’s when I felt at the mercy of God, and that’s
An international team of scientists led by researchers at The Scripps Research Institute has developed a straightforward technique to determine the ethnic origin of stem cells.
The team’s analysis of a variety of human embryonic stem cell lines currently in use in research laboratories around the world found that these cells originated largely from Caucasian and East Asian populations, with little representation from populations originating in Africa. In response to these results, the scientists used skin cells from an individual of West African Yoruba heritage to create a new stem cell line, the first to carry the genetic profile of

That induced embryonic stem cell has vaulted Toronto scientist Andras Nagy into this high-flying company in Scientific Magazine’s inaugural Top 10 awards for work in science-related endeavours.
“It’s an enormous honour and a recognition of the science we do in the lab, and what we do in Mount Sinai, and what we do in Toronto and what we do in Canada,”

Embryonic stem cells (ESC) can survive even when inserted into chains of polymers, in a process in which they are “weaved” into artificial and flexible tissues able to adapt to various types of transplants. In an innovative technique, stem cells could be used in the future to produce artificial organs, say researchers at University College London.
The technique was described in a study, published in Integrative Biology. It implements other research to shape living cells into engineered tissues, including a technique which would print a live tissue using an ink printer, which would substitute normal ink
