Apoptosis in human glioblastoma cells produced using embryonic stem cell–derived astrocytes expressing tumor necrosis factor–related apoptosis-inducing ligand

Abstract

Engineering of transgenic hTRAIL by using ES cell-derived astrocytes induced apoptosis in human malignant glioma cells while sparing nontumor astrocytes. The apoptotic effects of transgenic hTRAIL are greater than those of recombinant hTRAIL. Analysis of these results suggests that hTRAIL-expressing-ES cell-derived astrocytes should be considered in the development of new in vivo strategies to treat malignant human gliomas.
