TLDR
The extent to which in vitro differentiation of human pluripotent stem cells recapitulates bona fide human developmental haematopoiesis is discussed, and some future directions in the field are outlined.
Abstract
Haematopoietic stem cells (HSCs) emerge during embryogenesis and give rise to the adult haematopoietic system. Understanding how early haematopoietic development occurs is of fundamental importance for basic biology and medical sciences, but our knowledge is still limited compared with what we know of adult HSCs and their microenvironment. This is particularly true for human haematopoiesis, and is reflected in our current inability to recapitulate the development of HSCs from pluripotent stem cells in vitro In this Review, we discuss what is known of human haematopoietic development: the anatomical sites at which it occurs, the different temporal waves of haematopoiesis, the emergence of the first HSCs and the signalling landscape of the haematopoietic niche. We also discuss the extent to which in vitro differentiation of human pluripotent stem cells recapitulates bona fide human developmental haematopoiesis, and outline some future directions in the field.

From haematopoietic stem cells to complex differentiation landscapes

TL;DR: These evolving views of haematopoiesis have broad implications for the understanding of the functions of adult stem cells, as well as the development of new therapies for malignant and non-malignant haem atopoietic diseases.

Decoding human fetal liver haematopoiesis

TL;DR: A shift in the haemopoietic composition of fetal liver during gestation away from being predominantly erythroid, accompanied by a parallel change in differentiation potential of HSC/MPPs is demonstrated, which is validated to produce an integrated map of fetal liver haematopoiesis.

High-Spatial-Resolution Multi-Omics Sequencing via Deterministic Barcoding in Tissue

TL;DR: D deterministic barcoding in tissue for spatial omics sequencing (DBiT-seq) is presented for co-mapping of mRNAs and proteins in a formaldehyde-fixed tissue slide via next-generation sequencing (NGS) and can be adopted by researchers with no experience in microfluidics.

Biologic properties and enucleation of red blood cells from human embryonic stem cells. Commentary

TL;DR: It is shown that it is feasible to differentiate and mature human embryonic stem cells (hESCs) into functional oxygen-carrying erythrocytes on a large scale (10(10)-10(11) cells/6-well plate hESCs).

Definitive-like erythroid cells derived from human embryonic stem cells coexpress high levels of embryonic and fetal globins with little or no adult globin

TL;DR: The coexpression of both embryonic and fetal globins by definitive-type erythroid cells does not faithfully mimic either yolk sac embryonic or their fetal liver counterparts, but can serve as an invaluable tool to further explore molecular mechanisms.

Progressive divergence of definitive haematopoietic stem cells from the endothelial compartment does not depend on contact with the foetal liver

TL;DR: It is shown that the developmental switch from a `primary' VE-cadherin+CD45+ to a more `advanced' V E-c cadherin-CD45+, `double-positive' phenotype does not require contact of HSCs with the liver and is probably a function of developmental time.

Differentiation of human embryonic stem cells to HOXA+ hemogenic vasculature that resembles the aorta-gonad-mesonephros

TL;DR: This work shows that simultaneous modulation of WNT and ACTIVIN signaling yields CD34+ hematopoietic cells with HOXA expression that more closely resembles that of cord blood in the aorta-gonad-mesonephros (AGM), and provides an approach to mimic in vitro a key early stage in human heMatopoiesis for the generation of AGM-derived hematoietIC lineages from hESCs.

Hedgehog and Bmp Polarize Hematopoietic Stem Cell Emergence in the Zebrafish Dorsal Aorta

TL;DR: It is shown that while continued Hedgehog signaling from the overlying midline structures maintains the arterial program characteristic of the DA roof, a ventral Bmp4 signal induces the blood stem cell program in the DA floor.
