Generation of caudal-type serotonin neurons and hindbrain fate organoids from hPSCs

Project description:Serotonin (5-HT) neurons, the major components of the raphe nuclei, arise from ventral hindbrain progenitors. Based on the anatomical location and axonal projection, 5-HT neurons are coarsely divided into rostral and caudal groups. Here, we propose a novel strategy to generate hindbrain 5-HT neurons from human pluripotent stem cells (hPSCs), which involves the formation of ventral-type neural progenitor cells (NPCs) and stimulation of the hindbrain 5-HT neural development. A caudalizing agent, retinoid acid (RA), was used to direct the cells into the hindbrain cell fate. Approximately 30-40% of hPSCs successfully developed into 5-HT-expressing neurons using our protocol, with the majority acquiring a caudal rhombomere identity (r5-8). We further modified our monolayer differentiation system to generate 5-HT neuron-enriched hindbrain-like organoids. We have also suggested downstream applications of our 5-HT monolayer and organoid cultures to study neuronal response to gut microbiota. Our methodology could become a powerful tool for future studies related to 5-HT neurotransmission.

Transcription profiling of mouse E12.5 ePet-EYFP rostral and caudal serotonin (5HT) neurons purified by flow cytometry

Project description:The 5HT system is organized into rostral and caudal populations with discrete anatomical locations and opposite axonal trajectories in the developing hindbrain. 5HT neuron cell bodies in the rostral subdivision migrate to the midbrain and pons and extend ascending projections throughout the forebrain. 5HT cell bodies in the caudal subdivision migrate to the ventral medulla and caudal half of the pons and provide descending projections to the brainstem and spinal cord. Experiment Overall Design: We used microarrays to determine genes expressed by both rostral and caudal 5HT neurons as well as genes that are differentially expressed between rostral and caudal 5HT neurons at E12.5 when axon pathfinding and cell migration are underway. E12.5 neural tubes were isolated from ePet-EYFP embryos and dissected into a rostral domain (mesecephalic flexure to pontine flexure) and a caudal domain (pontine flexure to spinal cord). After cell dissociation (details under growth protocol), cells were subjected to fluorescent activated cell sorting (FACS) to obtain 4 cell populations. R+ = rostral ePetEYFP positive 5HT neurons; R- = YFP negative non-serotonergic cells in the rostral neural tube; C+ = caudal ePetEYFP positive 5HT neurons; C- = YFP negative non-serotonergic cells in the caudal neural tube. 200,000 cells for each of the 4 cell types (R+, R-, C+, C-) were collected for RNA extraction and hybridization to Affymetrix Mouse 430 2.0 arrays.

Uncovering the role of FOXA2 in the development of human serotonin neurons [scRNA-seq]

Project description:We used single cell RNA sequencing (scRNA-seq) to analyze the diversity of serotonin neurons derived from human pluripotent stem cells (hPSCs) and to compare the transcriptomic differences between FOXA2 knockout and wide type hPSCs-derived serotonin neurons.

Phosphoproteomics of cardiac organoids derived from ALPK3 knockout hPSCs

Project description:Pathogenic mutations in alpha kinase 3 (ALPK3) cause cardiomyopathy and a range of musculoskeletal defects. How ALPK3 mutations result in disease remains unclear and little is known about this atypical kinase. Using a suite of engineered human pluripotent stem cells (hPSCs) we show that ALPK3 localizes to the sarcomere, specifically at the M-Band. Both sarcomeric organization and calcium kinetics were disrupted in ALPK3 deficient hPSC derived cardiomyocytes. Further, cardiac organoids derived from ALPK3 knockout hPSCs displayed reduced force generation. Phosphoproteomic profiling of wildtype and ALPK3 null hPSC derived cardiomyocytes revealed ALPK3-dependant phospho-peptides were enriched for proteins involved in sarcomere function and protein quality control. We demonstrate that ALPK3 binds to the selective autophagy receptor SQSTM1 (Sequestome 1) and is required for the sarcomeric localization of SQSTM1. We propose that ALPK3 is a myogenic kinase with an integral role in the intracellular signaling networks underlying sarcomere maintenance required for continued cardiac contractility.

Modelling rostro-caudal neural tube regionalization from human embryonic stem cells with a microfluidic morphogenic gradient

Project description:Studies in animal models have been fundamental for understanding brain development but only a fraction of these findings have been validated in a human context. Here, we tissue-engineered a model (MiSTR) of human neural tube regionalization based on human embryonic stem cells (hESCs) and microfluidic cell culturing. By exposing differentiating hESCs to a WNT signalling gradient we mimicked early rostro-caudal neural patterning, and with >80% reproducibility generated a coherent tissue with progressive caudalization from forebrain over midbrain to hindbrain, including formation of isthmic organiser characteristics. Single-cell transcriptomics revealed that rostro-caudal organization was established already at 24 hours of differentiation, before expression of neural markers. Moreover, the transcriptomic hallmarks of rostro-caudal MiSTR organization accurately recapitulated gene expression patterns of the early rostro-caudal neural plate in mouse embryos. MiSTR thereby represents a novel in vitro model of human neurodevelopment to deconstruct and systematically analyze factors responsible for rostro-caudal neural tube patterning.
