Transcriptomic analysis of functional diversity of human umbilical cord blood hematopoietic stem/progenitor cells in erythroid differentiation

Abstract

Hematopoietic stem cells (HSC) give rise to all types of blood lineages, including red blood cells (RBC). Hematopoietic stem/progenitor cells (HSPC) are known to be functionally diverse in terms of their self-renewal potential and lineage output. Consequently, investigation of molecular heterogeneity in the differentiation potential of HSPC is vital to identify novel regulators that affect generation of specific cell types, especially RBC. Here, we compared the erythroid potential of CD34+ hematopoietic stem and progenitor cells from 50 different umbilical cord blood (UCB) donors and discovered that those donors gave rise to diverse frequencies of Glycophorin-A+ erythroid cells after in vitro differentiation,...

Hematopoietic stem cells (HSC) give rise to all types of blood lineages, including red blood cells (RBC). Hematopoietic stem/progenitor cells (HSPC) are known to be functionally diverse in terms of their self-renewal potential and lineage output. Consequently, investigation of molecular heterogeneity in the differentiation potential of HSPC is vital to identify novel regulators that affect generation of specific cell types, especially RBC. Here, we compared the erythroid potential of CD34+ hematopoietic stem and progenitor cells from 50 different umbilical cord blood (UCB) donors and discovered that those donors gave rise to diverse frequencies of Glycophorin-A+ erythroid cells after in vitro differentiation, despite having similar frequencies of phenotypic HSC initially. RNA sequencing revealed that genes involved in G protein-coupled receptor (GPCR) signaling were significantly up-regulated in the high-erythroid output donors. When we chemically modified two main signaling elements in this pathway, adenylyl cyclase (AC) and phosphodiesterase (PDE), we observed that inhibition of PDE led to 10 times higher yield of Glycophorin-A+ cells than activation of AC. Our findings suggest that GPCR signaling, and particularly the cAMP-related pathway, contributes to the diversity of erythroid potential among UCB donors.
