Abstract

OBJECTIVE: To explore the role of bromodomain and extra terminal (BET) bromodomain in hematopoietic differentiation from human enbryonic stem cells (hESC). METHODS: The effect of BET hematopoietic inhibitor I-BET151 on hematopoietic differentiation from hESC was detected by using a monolayer hematopoietic defferentiation model, immunofluorescence, flow cytometry and real-time PCR; moreover the role of I-BET151 in process of hematopoietic differentiation was explored by adding I-BET151 in different differentiation stages. RESULTS: The analysis results of immunofluorescence, flow cytometry and real-time PCR showed that I-BET 151 significantly inhibited the generation of CD43 positive hematopoietic stem and progenitor cells (HSPCs). It was found that the addition of I-BET 151 in different stages, including APLNR+ lateral plate mesoderm production, CD34+CD31+ hemogenic endothelium (HEP) generation and endothelial-to-hematopoietic transition, significantly suppressed the generation of CD43 positive hematopoietic progenitor cells. CONCLUSION: I-BET 151 inhibites hematopoietic differentiation from hESCs at several stages, suggesting that the BET bromodomain plays important roles in multiple stages of hematopoietic differentiation from hESCs.
