Crucial stem cell experiments? Stem cells, uncertainty, and single-cell experiments

I have previously argued that stem cell experiments cannot in principle demonstrate that a single cell is a stem cell ([reference omitted for anonymous review]). Laplane and others dispute this claim, citing experiments that identify stem cells at the single-cell level. This paper rebuts the counterexample, arguing that these alleged ‘crucial stem cell experiments’ do not measure self-renewal for a single cell, do not establish a single cell’s differentiation potential, and, if interpreted as providing results about single cells, fall into epistemic circularity. I then examine the source of the dispute, noting differences in philosophical and experimental perspectives.
