Transcription factor-based transdifferentiation of human embryonic to trophoblast stem cells

The study investigates the transcription factors involved in the development of human trophectoderm (TE) cells, which are progenitors of placental trophoblast. Researchers identified key transcription factors, including GATA2, GATA3, TFAP2C, KLF5, and MYC, that can induce the formation of trophoblast stem cells (iTSCs) from human embryonic stem cells. These iTSCs exhibit self-renewal and differentiation capabilities similar to natural trophoblast stem cells. The study highlights the critical roles of GATA2 and GATA3 in this transdifferentiation process. These findings enhance understanding of the transcription factor network in human TE and offer new methods for creating cellular models to study early human placental development and related diseases.
