5' scRNAseq of splenic CD3+ cells from immunodeficient mice injected with progenitor T-cells generated from naïve, non-expanded or SR1-expanded human cord blood-derived CD34+ cells

ABSTRACT: We report the gene expression profile of single cell peripheral CD3+ cells from immunodeficient mice injected with human progenitor T-cells (proT-cells). ProT-cell subsets were generated in vitro using human umbilical cord blood-derived CD34+ cells that were either non-expanded (naive), or expanded in vitro with the hydrocarbon receptor antagonist, StemRegenin-1 (SR1).

Exponential expansion of CD34+ cells in response to StemRegenin-1 occurs with minimal changes in gene expression

Project description:Hematopoietic stem/progenitor cell transplantation (HSCT) is a well-established treatment option for hematological and other disorders. Umbilical cord blood (UCB) is a rich source of hematopoietic stem and progenitor cells (HSPCs). Cluster of Differentiation (CD)34 is commonly used as a cell surface marker to identify and isolate HSPCs. Transplantation using a single UCB unit may be associated with delayed hematopoietic reconstitution as it may not contain a sufficient number of HSPCs required for adult transplantation. One way of overcoming this limitation is through ex vivo expansion of UCB-derived HSPCs using the aryl hydrocarbon receptor (AhR) antagonist, StemRegenin-1 (SR1), which promotes the expansion of HSPCs. Our study investigated the effects of SR1 on the transcriptome of expanded CD34+ cells from UCB, and we also report on a comparison between the transcriptome profiles of 7-day expanded and non-expanded CD34+ cells. CD34+ HSPCs expanded with SR1 for 7 days displayed two significantly downregulated genes, cytochrome P450, family 1, subfamily B, polypeptide 1 (CYP1B1) and erythrocyte membrane protein band 4.1-like 3 (EPB41L3), when compared to controls (without SR1). Transcriptome analysis of CD34+ HSPCs expanded for 7 days using SR1 revealed that 391 genes were significantly upregulated, while 456 genes were significantly downregulated when compared to non-expanded CD34+ cells. In conclusion, though hundreds of genes were differentially expressed between SR1-expanded and non-expanded CD34+ HSPCs, only two genes were significantly downregulated in cells expanded for 7 days with SR1 versus control at the same time point (without SR1).

Aryl hydrocarbon receptor antagonists promote the expansion of human hematopoietic stem cells

Project description:Although practiced clinically for more than 40 years, the use of hematopoietic stem cell (HSC) transplants remains limited by the ability to expand these cells ex vivo. An unbiased screen with primary human HSCs identified a purine derivative, StemRegenin 1 (SR1), that promotes the ex vivo expansion of CD34+ cells. Culture of HSCs with SR1 led to a 50-fold increase in cells expressing CD34 and a 17-fold increase in cells that retain the ability to engraft immunodeficient mice. Mechanistic studies show that SR1 acts by antagonizing the aryl hydrocarbon receptor (AHR). The identification of SR1 and AHR modulation as a means to induce ex vivo HSC expansion should facilitate the clinical use of HSC therapy. LGC006, a less potent SR1 analog, was also examined.
