Efficient generation of endothelial cells from human pluripotent stem cells and characterization of their functional properties
Although endothelial cells (ECs) have been derived from human pluripotent stem cells (hPSCs),large-scale generation of hPSC-ECs remains challenging and their functions are not well characterized. Here we report a simple and efficient three-stage method that allows generation of approximately 98 and 9500 ECs on day 16 and day 34,respectively,from each human embryonic stem cell (hESC) input. The functional properties of hESC-ECs derived in the presence and absence of a TGF$$-inhibitory molecule SB431542 were characterized and compared with those of human umbilical vein endothelial cells (HUVECs). Confluent monolayers formed by SB431542(+) hESC-ECs,SB431542(-) hESC-ECs,and HUVECs showed similar permeability to 10,000 Da dextran,but these cells exhibited striking differences in forming tube-like structures in 3D fibrin gels. The SB431542(+) hESC-ECs were most potent in forming tube-like structures regardless of whether VEGF and bFGF were present in the medium; less potent SB431542(-) hESC-ECs and HUVECs responded differently to VEGF and bFGF,which significantly enhanced the ability of HUVECs to form tube-like structures but had little impact on SB431542(-) hESC-ECs. This study offers an efficient approach to large-scale hPSC-EC production and suggests that the phenotypes and functions of hPSC-ECs derived under different conditions need to be thoroughly examined before their use in technology development.

Integrated analysis of microRNA and mRNA expression profiles in physiological myelopoiesis: role of hsa-mir-299-5p in CD34+ progenitor cells commitment
Hematopoiesis entails a series of hierarchically organized events that proceed throughout cell specification and terminates with cell differentiation. Commitment needs the transcription factors' effort,which,in concert with microRNAs,drives cell fate and responds to promiscuous patterns of gene expression by turning on lineage-specific genes and repressing alternate lineage transcripts. We obtained microRNA profiles from human CD34+ hematopoietic progenitor cells and in vitro differentiated erythroblasts,megakaryoblasts,monoblasts and myeloblast precursors that we analyzed together with their gene expression profiles. The integrated analysis of microRNA-mRNA expression levels highlighted an inverse correlation between microRNAs specifically upregulated in one single-cell progeny and their putative target genes,which resulted in downregulation. Among the upregulated lineage-enriched microRNAs,hsa-miR-299-5p emerged as having a role in controlling CD34+ progenitor fate,grown in multilineage culture conditions. Gain- and loss-of-function experiments revealed that hsa-miR-299-5p participates in the regulation of hematopoietic progenitor fate,modulating megakaryocytic-granulocytic versus erythroid-monocytic differentiation.
