New study refutes existence and clinical potential of very small embryonic-like stem cells
Date:7/28/2013

findings. Although they used a variety of protocols, they failed to find VSELs derived from mouse bone marrow that could turn into specialized blood cells. Instead, the "VSELs" appeared to be artifacts such as cell debris and fragments from dying cells. "Our findings clearly refute the basis in mouse studies that VSELs have the potentials claimed, and therefore call into question claims that these cells have potential for clinical application in humans," Weissman says.

Another article that will be published on the same day in the journal Cell Stem Cell reviews the controversy surrounding VSELs and includes wide-ranging commentary from experts in the field.
