Transcriptomic features of trophoblast lineage cells derived from BMP4-treated human induced pluripotent stem cells. Transcriptomic features of trophoblast lineage cells derived from BMP4-treated human induced pluripotent stem cells

We explored the trophoblast differentiation model using human induced pluripotent stem cells (hiPSCs) to gain new insights into the early development of human placenta. In our previous study, we have optimized culture conditions for hiPSC-derived trophoblasts. To identify the characteristics of trophoblast lineage cells derived from BMP4-treated hiPSCs, we collected cells using a pan-trophoblast marker, KRT7, with flow cytometry and performed comprehensive gene expression analysis. Overall design: For characterization of BMP4-treated hiPSCs, four types of hiPSCs were treated with 50ng/ml BMP4 for 10 days. Subsequently, KRT7-positive cells were purified from differentiated cells using flow cytometry and analyzed using DNA microarray.
