Researchers at Scripps have converted skin cells directly to heart muscle:
“This work represents a new paradigm in stem cell reprogramming,” said Scripps Research Associate Professor Sheng Ding, Ph.D., who led the study. “We hope it helps overcome major safety and other technical hurdles currently associated with some types of stem cell therapies.”
I found this an interesting (and flawed) analogy, though:
“In 11 days, we went from skin cells to beating heart cells in a dish,” said Ding. “It was phenomenal to see.”
Ding points out the protocol is fundamentally different from what has been done by other scientists in the past and notes that giving the cells a different kind of signal could turn them into brain cells or pancreatic cells.
“It is like launching a rocket,” he said. “Until now, people thought you needed to first land the rocket on the moon and then from there you could go to other planets. But here we show that just after the launch you can redirect the rocket to another planet without having to first go to the moon. This is a totally new paradigm.”
Actually, I don’t know anyone who thought that except for people who were promulgating a straw-man argument against the Vision for Space Exploration. For instance, some claimed that Bush’s plan was foolish because it proposed “building a Kennedy Space Center on the moon.” But the plan was never to land on the moon, and then depart from there for other planets. It was to utilize the resources of the moon to provide propellants and other consumables to interplanetary ships already in orbit, and save the expense of launching them all from earth. It may well be that this is equally economically impractical in the near term, but it’s not what the critics (and the Scripps researcher) seem to think it is.
By the way, the article says that these researchers are scientists, but I think they’re engineers. Or perhaps some blend of both.
