Network mapping of primary CD34+ cells by Ampliseq based whole transcriptome targeted resequencing identifies unexplored differentiation regulatory relationships.

With the exception of a few master transcription factors, regulators of neutrophil maturation are poorly annotated in the intermediate phenotypes between the granulocyte-macrophage progenitor (GMP) and the mature neutrophil phenotype. Additional challenges in identifying gene expression regulators in differentiation pathways relate to challenges wherein starting cell populations are heterogeneous in lineage potential and development, are spread across various states of quiescence, as well as sample quality and input limitations. These factors contribute to data variability make it difficult to draw simple regulatory inferences.

Filling the void: allogeneic myeloid cells for transplantation.

Purpose Of Review: The success of allogeneic haematopoietic stem and progenitor cell (HSPC) transplantations remains inconsistent. Umbilical cord blood (UCB) is a promising source of HSPCs for transplantation, but low cell yield hampers its widespread use. Multiple strategies are being developed to manipulate UCB to either increase HSPC content or enhance bone marrow homing upon transfusion.
