Single-Cell RNA-Seq Study Showing the Effect of Healthy and Cencer Cells on HSCs

Project description:Hematopoietic stem cells (HSCs) are highly sensitive to signals from their surrounding microenvironment, yet the precise effects of healthy versus malignant cells on HSC behavior remain poorly understood. In this study, we applied single-cell RNA sequencing (scRNA-seq) to profile HSCs exposed to either exosomes from healthy primary cells or cancer-derived cells. Our analyses revealed distinct transcriptional programs induced by each condition.

Gene expression profiling of LT-HSCs and ST-HSCs conditionally expressing MLL-ENL

Project description:We have developed a new conditional transgenic mouse showing that MLL-ENL, at an endogenous-like expression level, induces leukemic transformation selectively in LT-HSCs. To investigate the molecular mechanism of leukemic transformation in LT-HSCs conditionally expressing MLL-ENL, we preliminarily performed comprehensive gene expression profiling of CreER-transduced LT-HSCs and ST-HSCs using cDNA microarray analysis. For initial screening of candidate genes invloved in the leukemic transformation, total RNA was extracted from colony-forming cells derived from LT-HSCs and ST-HSCs transduced with CreER or mock. Four samples were analyzed, and CreER-transduced LT/ST-HSC-derived cells were compared with mock-transduced LT/ST-HSC-derived cells, while CreER/mock-transduced LT-HSC-derived cells were compared with CreER/mock-transduced ST-HSC-derived cells.

Gene expression profiling of mouse HSCs treated with Eltrombopag

Project description:Eltrombopag, a small molecule thrombopoietin receptor (TPO-R) agonist and potent intracellular iron chelator, has shown remarkable efficacy to stimulate sustained multilineage hematopoiesis in patients with bone marrow failure syndromes, suggesting an effect at the most immature hematopoietic stem and multipotent progenitor level. While the functional and molecular effects of Eltrombopag on megakaryopoiesis have been carefully studied in the recent past, insights into its mechanistic impact on the earliest stages of hematopoiesis have been limited. Additionally, previous studies also revealed molecular pathway of Eltrombopag apart from stimulation of TPO signaling, detail characterization remains to be addressed. In this study, we investigated the effects of Eltrombopag, in comparison with TPO, on highly-purified primary hematopoietic stem cells (HSCs) from healthy human donors. The binding of Eltrombopag to TPO-R is species-specific to human and primate cells. we also utilized HSCs isolated mouse as separation-of-function models to directly assess the molecular effect of Eltrombopag on HSCs independent of TPOR stimulation.
