In an allogeneic haematopoietic cell ... progenitor cells were used as lineage markers (Fig. 1a). Given that such mutations occur about once every three weeks 2, we could trace the ancestries ...

To identify such multipotent reprogramming factors, Zhang turned to a genetic tool called lineage tracing. Zhang generated several mouse models that express fluorescent reporters in neural progenitor ...

Numerous studies have proposed that new β cells are generated by the differentiation of adult stem cells or progenitor cells ... demonstrated with genetic lineage tracing in adult mice that ...
