Methods for producing lymphocyte progenitors

Abstract

The invention relates to a method for producing a lymphocyte progenitor, the method comprising culturing a pluripotent stem cell (PSC)-derived CD34+ cell at an air-liquid interface (ALI). The invention also relates to a method for producing a B-cell progenitor, the method comprising co-culturing a PSC-derived CD34+ cell and a stromal cell in a medium comprising a CD117 activator and a NOTCH1 inhibitor. The invention further relates to a T-cell progenitor and a B-cell progenitor when produced by the methods of the invention and to use of the T-cell progenitor in the manufacture of T cell with defined antigen specificity, optionally a chimeric antigen receptor (CAR) T cell, and use of the B-cell progenitor in the manufacture of an antibody.
