摘要:

为探究人类不同发育时期巨核细胞的分子特征,基于人类胚胎期卵黄囊、胎肝和成年骨髓巨核细胞的单细胞转录组测序数据,从分子特征、基因调控网络等方面分别对其分子差异进行生物信息学分析。结果表明,胚胎期巨核细胞具有较强的增殖特征,高表达细胞增殖相关的转录因子;而成年期巨核细胞具有较强的血小板生成特征,高表达与巨核细胞分化成熟相关的转录因子。研究结果为研究不同发育阶段巨核细胞及其子代血小板的功能差异提供了理论依据。

Abstract:

To explore the molecular characteristics of human megakaryocytes at different development stages, based on the single-cell RNA sequence data of the human embryonic yolk sac, fetal liver, and adult bone marrow megakaryocytes, the molecular differences were analyzed by bioinformatics from the aspects of molecular characteristics and gene regulation network. The results showed that, embryonic stage megakaryocytes had higher proliferation characteristics and highly expressed transcription factors related to cell proliferation, while adult stage megakaryocytes had strongly characteristics of platelet-producing and highly expressed transcription factors related to megakaryocyte differentiation and maturation. This paper provided a theoretical basis for studying the functional differences of megakaryocytes and their progeny platelets at different developmental stages.

Key words: embryonic stage, adult stage, megakaryocyte, single-cell RNA sequence, molecular characteristics
