| Abstract |
The expression of a specific combination of transcription factors (TFs) in the multipotent progenitor cells (MPCs) is critical for determining pancreatic cell fate. NKX6.1 expression in PDX1+ MPCs is required for functional β cell generation. We have recently demonstrated the generation of a novel population of human pluripotent stem cell (hPSC)-derived MPCs that exclusively express NKX6.1, independently of PDX1 (PDX1-/NKX6.1+). Therefore, the aim of this study was to characterize this novel population to elucidate its role in pancreatic development. The hPSCs were exposed to two differentiation protocols to generate MPCs that were analyzed using different techniques. Based on the expression of PDX1 and NKX6.1, we generated three different populations of MPCs, two of them were NKX6.1+. One of these NKX6.1 populations coexpressed PDX1 (PDX1+/NKX6.1+) which is known to mature into functional β cells, and an additional novel population did not express PDX1 (PDX1-/NKX6.1+) with an undefined role in pancreatic cell fate. This novel population was enriched using our recently established protocol, allowing their reorganization in three-dimensional (3D) structures. Since NKX6.1 induction in MPCs can direct them to endocrine and/or ductal cells in humans, we examined the coexpression of endocrine and ductal markers. We found that the expression of the pancreatic endocrine progenitor markers chromogranin A (CHGA) and neurogenin 3 (NGN3) was not detected in the NKX6.1+ 3D structures, while few structures were positive for NKX2.2, another endocrine progenitor marker, thereby shedding light on the origin of this novel population and its role in pancreatic endocrine development. Furthermore, SOX9 was highly expressed in the 3D structures, but cytokeratin 19, a main ductal marker, was not detected in these structures. These data support the existence of two independent NKX6.1+ MPC populations during human pancreatic development and the novel PDX1-/NKX6.1+ population may be involved in a unique trajectory to generate β cells in humans. |

Attention Score in Context
This research output has an Altmetric Attention Score of 2. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 11 January 2019.
All research outputs
#14,974,347
of 23,035,022 outputs
Outputs from Stem Cell Research & Therapy
#1,217
of 2,431 outputs
Outputs of similar age
#198,826
of 329,113 outputs
Outputs of similar age from Stem Cell Research & Therapy
#40
of 70 outputs
Altmetric has tracked 23,035,022 research outputs across all sources so far. This one is in the 32nd percentile – i.e., 32% of other outputs scored the same or lower than it.
So far Altmetric has tracked 2,431 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 5.1. This one is in the 44th percentile – i.e., 44% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 329,113 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 36th percentile – i.e., 36% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 70 others from the same source and published within six weeks on either side of this one. This one is in the 32nd percentile – i.e., 32% of its contemporaries scored the same or lower than it.
