Method for regenerating T cells and applications thereof

Abstract

The present invention relates to a method for inducing the transdifferentiation of B lymphoid cells into T lymphoid cells using transcription factor Hoxb5, and related products and applications thereof. The method of the present invention specifically comprises: introducing Hoxb5, a nucleic acid molecule encoding Hoxb5 or a construct comprising the nucleic acid molecule into the B lymphoid cells to obtain the B lymphoid cells with overexpressed Hoxb5; then implanting the obtained B lymphoid cells into the body of a subject to obtain regenerated T cell progenitor cells by way of transdifferentiation, and then the T cell progenitor cells differentiate into mature T cells with functions. The regenerated T cells obtained using the method of the present invention are not only functionally normal, but also show no risk of tumorigenesis or extremely low risk of tumorigenesis.
