Are somatic stem cells pluripotent or lineage-restricted? D'Amour, K. A. & Gage, F. H. Nature Medicine March (2002). Extravagant claims have been made about the plasticity of supposedly lineage-restricted stem cells, but it has proved difficult to substantiate the evidence. This News and Views article reports on the failure to reproduce an experiment in which neural stem cells seemed to generate haematopoietic cells.
