NIH Director Francis Collins has approved four more human embryonic stem cell lines as eligible for federal taxpayer funding. The latest approval brings the total to 146. The four new lines are all from UCLA. The new lines, designated by the deriving lab as "UCLA 7", "UCLA 8", "UCLA 9", and "UCLA 10", join six previous UCLA lines approved by NIH for taxpayer funding--UCLA 1-3 approved April 27, 2010 and UCLA 4-6 approved February 3, 2011. All of the lines were apparently derived from human embryos after the new NIH guidelines went into effect in July 2009. NIH doesn't provide details on the cells themselves or their derivation.

In the meantime, Adult Stem Cells continue to provide the gold standard for patient treatment, and the only stem cell type with published positive results at improving health and saving lives.
