Functional Connection with Cardiac Tissues Confers Maturation Phenotypes in hPSC-Derived PHOX2B::GFP Expressing Sympathetic Neurons

ABSTRACT: Neurons derived from human pluripotent stem cells (hPSCs) are a remarkable tool for modeling human neural development and diseases. However, it remains largely unknown whether the hPSC-derived neurons can be functionally coupled with their target tissues in vitro, which is essential for understanding inter-cellular physiology and further translational studies. Here, we demonstrate that hPSC-derived sympathetic neurons can be obtained from hPSCs and that the resulting neurons form physical and functional connections with cardiac muscle cells. By use of multiple hPSC reporter lines, we recapitulated human autonomic neuron development in vitro, and successfully isolated PHOX2B::eGFP+ neurons exhibiting sympathetic marker expression, electrophysiological properties, and norepinephrine secretion. With pharmacological and optogenetic manipulations, the PHOX2B::eGFP+ neurons controlled the beating rates of cardiomyocytes, and their physical interaction led to neuronal maturation. Our study lays a foundation for the specification of human sympathetic neurons and for the hPSC-based neuronal control of end organs in a dish.

Our study lays a foundation for the specification of human sympathetic neurons and for the hPSC-based neuronal control of end organs in a dish. Using the four genetic reporter systems (OCT4::eGFP, SOX10::eGFP, ASCL1::eGFP, and PHOX2B::eGFP reporter hESC lines), we were able to purify discrete cell populations at four differentiation stages, recapitulating the sympathoadrenal differentiation process in vitro with purified and defined populations in four specific differentiation stages. We performed transcriptome analysis of OCT4::eGFP+ cells (3 biological replicates, representing undifferentiated hESCs), SOX10::eGFP+ cells (3 biological replicates, multi-potent neural crest), ASCL1::eGFP+ cells (3 biological replicates, putative sympathoadrenal progenitors), and PHOX2B::eGFP+ cells (2 biological replicates, putative sympathetic neuronal precursors).

Identification of Phox2b-regulated genes by expression profiling of cranial motoneuron precursors on NeuroDev microarray

Project description:Branchiomotor neurons are an important class of cranial motor neurons that innervate the branchial-arch-derived muscles of the face, jaw and neck. They arise in the ventralmost progenitor domain of the rhombencephalon characterized by expression of the homeodomain transcription factors Nkx2.2 and Phox2b. Phox2b in particular plays a key role in the specification of branchiomotor neurons. In its absence, generic neuronal differentiation is defective in the progenitor domain, and no branchiomotor neurons are produced. Conversely, ectopic expression of Phox2b in spinal regions of the neural tube promotes cell cycle exit and neuronal differentiation and at the same time induces genes and an axonal phenotype characteristic for branchiomotor neurons. How Phox2b exerts its pleiotropic functions, both as a proneural gene and a neuronal subtype determinant, has remained unknown. To gain further insight into the genetic programme downstream of Phox2b we searched for novel Phox2b-regulated genes by cDNA microarray (here NeuroDev slides) analysis of facial branchiomotor neuron precursors from heterozygous and homozygous Phox2b mutant embryos. Keywords: Phox2b-regulated genes identification Four biological replicates each in dye swap

Transcription profiling of human neuroblastoma cell line expressing PHOX2B

Project description:Neuroblastoma is an embryonal tumour of the peripheral sympathetic nervous system (SNS). One of the master regulator genes for peripheral SNS differentiation, the homeobox transcription factor PHOX2B, is mutated in familiar and sporadic neuroblastomas. Here we report that inducible expression of PHOX2B in the neuroblastoma cell line SJNB-8 down-regulates MSX1, a homeobox gene important for embryonic neural crest development. Inducible expression of MSX1 in SJNB-8 caused inhibition of both cell proliferation and colony formation in soft agar. Affymetrix micro- array and Northern blot analysis demonstrated that MSX1 strongly up-regulated the Delta-Notch pathway. These experiments describe for the first time regulation of the Delta-Notch pathway by MSX1, and connect these genes to the PHOX2B oncogene, indicative of a role in neuroblastoma biology. Experiment Overall Design: Time course experiments of two independent clones (K2 and K5), with 2 or 4 time points, respectively.

Predicting the functional states of human iPSC-derived neurons with single-cell RNA-seq and electrophysiology

Project description:Neural progenitors derived from human pluripotent stem cells (hPSCs) develop into electrophysiologically active neurons at heterogeneous rates, which can confound disease-relevant discoveries in neurology and psychiatry. The goal of this study was to resolve the diversity of functional states of hPSC-derived neurons in vitro by combining patch clamping with morphological and RNA-sequencing analysis of single neurons (Patch-seq).

Self-organized amniogenesis by human pluripotent stem cells in a biomimetic implantation-like niche

Project description:In this work, we generated early human amnion-like tissues by culturing human pluripotent stem cells (hPSCs) in a bioengineered implantation-like niche in vitro. To explore the gene expression profile of hPSC-derived amnion-like cells (hPSC-amnion), we performed mRNA-sequencing for both undifferentiated hPSCs and hPSC-amnion. Here we show that hPSC-amnion differs from hPSCs by actively regulating a comprehensive set of transcriptional regulation network and developmental signaling pathways such as BMP-SMAD signaling.

Transcriptomics during the differentiation of human pluripotent stem cells to hepatocyte-like cells

Project description:Human pluripotent stem cells (hPSCs) can differentiate into all cell types in the body that may replace current cell sources applied in regenerative medicine, cell therapy, drug discovery and development and general research. Human PSC-derived hepatocyte-like cells (HLCs) have the potential to replace primary hepatocytes and other cell models applied in liver disease treatment and drug discovery and development. These cells share many features with their in vivo counterparts however, the generation of fully functional hPSC-derive HLCs is still lacking, which prevent their application in the previously mentioned fields. This study followed the transcriptome dynamics during the differentiation of hPSC-derived HLCs at definitive endoderm, hepatoblast, early HLC and late HLC developmental stages and the controls hPSCs and human liver tissues which consists of at least 70% hepatocytes. The aim is to reveal expression deviations between hPSC-derived hepatocytes and their in vivo counterparts that may contribute to the modification of differentiation protocols to generate fully functional hepatocytes.
