• Protocol for the generation of HLF+ HOXA+ human hematopoietic progenitor cells from pluripotent stem cells. STAR protocols Zheng, S. L., Fowler, J. L., Chen, J. Y., Li, C., Lin, E., Nguyen, A. T., Chen, A., Daley, G. Q., Ang, L. T., Loh, K. M. 2025; 6 (1): 103592

  Abstract

  Hematopoietic stem cells (HSCs) generate blood and immune cells. Here, we present a protocol to differentiate human pluripotent stem cells (hPSCs) into hematopoietic progenitors that express the signature HSC transcription factors HLF, HOXA5, HOXA7, HOXA9, and HOXA10. hPSCs are dissociated, seeded, and then sequentially differentiated into posterior primitive streak, lateral mesoderm, artery endothelium, hemogenic endothelium, and hematopoietic progenitors through the sequential addition of defined, serum-free media. This 10-day protocol enables the manufacturing of blood and immune cells in monolayer cultures. For complete details on the use and execution of this protocol, please refer to Fowler and Zheng et al.1.

• Protocol for efficient generation of human artery and vein endothelial cells from pluripotent stem cells. STAR protocols Loh, K. M., Zheng, S. L., Liu, K. J., Yin, Q., Amir-Ugokwe, Z. A., Jha, S. K., Qi, Y., Wazny, V. K., Nguyen, A. T., Chen, A., Njunkeng, F. M., Cheung, C., Spiekerkoetter, E., Red-Horse, K., Ang, L. T. 2024; 6 (1): 103494

  Abstract

  Blood vessels permeate all organs and execute myriad roles in health and disease. Here, we present a protocol to efficiently generate human artery and vein endothelial cells (ECs) from pluripotent stem cells within 3-4 days of differentiation. We delineate how to seed human pluripotent stem cells and sequentially differentiate them into primitive streak, lateral mesoderm, and either artery or vein ECs. We differentiate stem cells in defined, serum-free culture media in monolayers, without feeder cells or genetic manipulations. For complete details on the use and execution of this protocol, please refer to Ang et al. 1.

• Lineage-tracing hematopoietic stem cell origins in vivo to efficiently make human HLF+ HOXA+ hematopoietic progenitors from pluripotent stem cells. Developmental cell Fowler, J. L., Zheng, S.

  Abstract

  The developmental origin of blood-forming hematopoietic stem cells (HSCs) is a longstanding question. Here, our non-invasive genetic lineage tracing in mouse embryos pinpoints that artery endothelial cells generate HSCs. Arteries are transiently competent to generate HSCs for 2.5 days (∼E8.5-E11) but subsequently cease, delimiting a narrow time frame for HSC formation in vivo. Guided by the arterial origins of blood, we efficiently and rapidly differentiate human pluripotent stem cells (hPSCs) into posterior primitive streak, lateral mesoderm, artery endothelium, hemogenic endothelium, and >90% pure hematopoietic progenitors within 10 days. hPSC-derived hematopoietic progenitors generate T, B, NK, erythroid, and myeloid cells in vitro and, critically, express hallmark HSC transcription factors HLF and HOXA5-HOXA10, which were previously challenging to upregulate. We differentiated hPSCs into highly enriched HLF+ HOXA+ hematopoietic progenitors with near-stoichiometric efficiency by blocking formation of unwanted lineages at each differentiation step. hPSC-derived HLF+ HOXA+ hematopoietic progenitors could avail both basic research and cellular therapies.

• Creating artificial signaling gradients to spatially pattern engineered tissues. Current opinion in biotechnology Zheng, S. L., Loh, K. M. 2022; 78: 102810

  Abstract

  Artificially constructing a fully-fledged tissue - comprising multiple cell types whose identities and spatial arrangements reflect those of a native tissue - remains daunting. There has been impressive progress in generating three-dimensional cell cultures (often dubbed 'organoids') from stem cells. However, it is critical to appreciate that not all such three-dimensional cultures will intrinsically self-organize to spontaneously recreate native tissue architecture. Instead, most tissues in vivo are exogenously patterned by extracellular signaling gradients emanating from organizer cells located outside the tissue. Innovations to impose artificial signaling gradients - using microfluidics, optogenetics, or introducing organizer cells - could thus prove decisive to create spatially patterned tissues in vitro. Additionally, unified terminology to describe these tissue-like simulacra as 'aggregates', 'spheroids', or 'organoids' will be critical for the field.
