Hi Everybody: This si for those who got exccited about the recent news on embryonic stem cells created by transfecting skin fibroblasts with some specific genes.. http://www.boston.com/news/education/higher/articles/2007/12/17/caution_urged_in_new_method_for_stem_cells/ I have my own suspicion that these cells might be the product of neosis, which in the long run may turn tumorigenic.
