Stem cells grown from skin cells show early aging and other abnormalities compared with embryonic stem cells, say U.S. scientists.
They compared 25 human embryonic stem cell lines with 8 induced stem cell lines created from skin cells, USA Today reported.
The biologists at Stem Cell and Regenerative Medicine International in Worcester, Mass. found the embryonic stem cells grew about 1,000 times more readily than the induced cells. In addition, the induced stem cells "significantly increased apoptosis (cell death), severely limited growth and expansion capability, as well as a substantially decreased hematopoietic (blood cell) colony forming capability," the researchers wrote.
The study appears in the journal Stem Cell.
"The authors show that induced stem cells are not of the same 'quality' as embryonic stem cells, and that induced-derived cell types tend to age and die earlier than those derived from embryonic cells," said Maria Blasco, a biologist at the Spanish National Cancer Center in Madrid, USA Today reported. She was not part of the study.

Dr. Lanza and Advanced Cell Technology will be the FIRST to HEAL the Blind sicne Jesus. The ENTIRE medical industry is designed to TREAT and TREAT diseases and ailments. Stem CEll Regenerative Medicine will SAVE Our Country from the HealthCare EXploding Costs. No more $300,000 Triple Bipass' or the costs associated. Advanced Cell Technology secures its hESC's from the Blastomere Process which is identical to IVF process of NOT harming the embryo to test for a HEALTHY embryo. ONE Cell is taken and the Stemcells are developed this way.
