Changing potency by spontaneous fusion

Abstract

Recent reports have suggested that mammalian stem cells residing in one tissue may have the capacity to produce differentiated cell types for other tissues and organs 1-9. Here we define a mechanism by which progenitor cells of the central nervous system can give rise to non-neural derivatives. Cells taken from mouse brain were co-cultured with pluripotent embryonic stem cells. Following selection for a transgenic marker carried only by the brain cells, undifferentiated stem cells are recovered in which the brain cell genome has undergone epigenetic reprogramming. However, these cells also carry a transgenic marker and chromosomes derived from the embryonic stem cells. Therefore the altered phenotype does not arise by direct conversion of brain to embryonic stem cell but rather through spontaneous generation of hybrid cells. The tetraploid hybrids exhibit full pluripotent character, including multilineage contribution to chimaeras. We propose that transdetermination consequent to cell fusion 10 could underlie many observations otherwise attributed to an intrinsic plasticity of tissue stem cells 9.

  • There is an absence of transplant-to-host cell fusion events.

    “indicating the absence of transplant-to-host cell fusion events”

    From Xenotransplanted human cortical neurons reveal species-specific development and functional integration into mouse visual circuits (2019) · cites this paper as Ying et al., 2002

    The discussion (page not identified in the index) reports spontaneous fusion between embryonic stem cells and brain cells in co-culture and advises checking both donor and host markers. The blastocyst-injection passage describes contributions from hybrids formed before injection; it does not establish whether transplanted cells fused with host cells. A search for transplant-to-host fusion found no passage establishing its absence. (LLM, conf=0.74)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
