During the culture, the researchers infected the CD34+ cells with infections carrying reprogramming factors, genes normally expressed in embryonic stem cells that may reset the bloodstream cells to an embryonic state. Colonies of cells exhibiting physical characteristics comparable to embryonic stem cells appeared about fourteen days after the procedure. To determine whether these cells were functionally similar to Sera cells also, the researchers analyzed the CD34+ iPS cell lines to see if they had obtained stem cell markers, the initial mix of proteins that layer the cells’ surface and differentiate them from other types of cells.About Bayer Health care The Bayer Group is usually a worldwide enterprise with primary competencies in the areas of healthcare, nutrition and high-tech components.
