I was inspired by the presentation made in class about stem cells to do a little research on the topic. I found out that on January 29th, a new method for making stem cells was announced in the journal Nature.
Apparently, scientists can take cells from a mouse spleen and expose to them to an acidic environment. Upon doing so, these cells become pluripotent. This is very spectacular because scientists neither have to manipulate the nucleus or tinker with the translation process. This is a phenomenal discovery.
