Closure, function, emergence, semiosis, and life: the same idea? Reflections on the concrete and the abstract in theoretical biology.

abstract：:Recent discoveries have demonstrated the extraordinary plasticity of tissue-derived stem cells, raising fundamental questions about cell lineage relationships and suggesting the potential for novel cell-based therapies. We have examined this phenomenon in a potential reciprocal relationship between stem cells derived ...
