Multi-tissue microphysiological system captures integrated responses to nutritional overload and metabolic therapy

ABSTRACT: This study used a human six-tissue microphysiological system to examine how shared multi-tissue interaction, graded nutrient exposure, and pharmacologic perturbation shape tissue-specific transcriptional programs relevant to systemic glucose regulation. The MOTIVE-6 platform integrated hiPSC-derived midbrain organoids, intestinal epithelium, liver organoids, pancreatic islets, visceral adipocytes, and skeletal muscle in a shared circulating media environment. Bulk RNA-seq was performed on individual tissue compartments after four days of culture under Low, Mid, or High nutrient conditions, with additional High-nutrient conditions treated with metformin or semaglutide. Matched isolation cultures were used to distinguish transcriptional effects associated with multi-tissue interaction from those observed in independently cultured tissues. This dataset enables analysis of tissue-specific responses to inter-tissue signaling, nutrient state, and anti-diabetic drug exposure in a perfused human multi-tissue model.

Human microphysiological systems of aging recreate the in vivo process expediting evaluation of anti-gerontic strategies

Project description:The search for biological mechanisms of human aging is stalled by a lack of suitable models and it remains unknown whether, and to what degree, rejuvenation reported in rodents translates to people. Here we report a hiPSC-derived microphysiological system modelling the white adipose tissue-liver axis in the presence of heterochronic human serum to study aging and rejuvenation in humans. We reveal changes in functional and molecular hallmarks of aging and rejuvenation, and we investigate unknown biomarkers and mechanisms of plasticity in human tissue aging as well as potential rejuvenation strategies. The microphysiological chip recapitulates, in 4 days, aging-associated hallmarks that occur after decades of aging in people, including gerontic shifts in gene expression and oxidative DNA damage. We uncover unknown signaling networks in human aging, knock-on effects of aging in fat on liver, sexual polymorphisms of aging, tissue memory of age, and develop a custom machine learning model for biological age. Combining heterochronic human serum with the microphysiological system allows for rapidly establishing human tissue aging, discovering clinically relevant mechanisms, biomarkers, and testing of anti-gerontic approaches.

Human Neural Organoid Microphysiological Systems Show the Building Blocks Necessary for Basic Learning and Memory

Project description:Brain Microphysiological Systems including neural organoids derived from human induced pluripotent stem cells offer a unique lens to study the intricate workings of the human brain. This paper investigates the foundational elements of learning and memory in neural organoids, by quantifying immediate early gene expression in response to chemical modulation, input-specific short- and long-term synaptic plasticity, neuronal network dynamics, connectivity, and criticality to demonstrate the utility of these organoids in basic science research. Neural organoids showed synapse formation, glutamatergic and GABAergic receptor expression, immediate early gene expression basally and evoked, functional connectivity, criticality, and synaptic plasticity in response to theta-burst stimulation. In addition, pharmacological interventions on GABAergic and glutamatergic receptors, and input-specific theta-burst stimulation further shed light on the capacity of neural organoids to mirror synaptic modulation, short- and long-term potentiation and depression, demonstrating their potential as tools for studying neurophysiological and neurological processes and informing therapeutic strategies for diseases.

Dissecting Semaglutide-dependent transcriptome response in obesity and osteoarthritis across tissues at single-cell resolution

Project description:The clinical observations of semaglutide cannot be fully explained by the classical GLP-1R signaling, indicating that semaglutide may exert its effects through a more complex multi tissue regulatory network. Based on this background, this study utilized high-fat diet (HFD) - induced obesity and surgery induced osteoarthritis (OA) models to simulate metabolic joint complications. By systematically collecting peripheral blood (PB), bone marrow (BM), liver, brain tissue, and skeletal muscle from C57BL/6 mice, and integrating 10x Genomics single-cell transcriptome sequencing, we constructed a cross tissue cell atlas that covers the immune, nervous, and motor metabolic systems under treatment with semaglutide. In addition, we compared the gene expression disturbances in mouse tissues after administration of semaglutide. Through these comparisons, we can more accurately decipher the specific effects of semaglutide treatment on gene expression in mice, thereby gaining a deeper understanding of their mechanisms of action in vivo.

Electro-metabolic coupling in multi-chambered vascularized human cardiac organoids

Project description:The study of cardiac physiology and disease is hindered by physiological differences between humans and small-animal models. Here, we report the generation of multi-chambered vascularized human cardiac organoids under anisotropic stress, and their applicability to study electro-metabolic coupling in cardiac tissue. The organoids are derived from human induced pluripotent stem cells, and integrate sensors for the simultaneous measurement of oxygen uptake, extracellular field potentials and cardiac contraction at resolutions higher than 10 Hz. The microphysiological system allowed us to find that 1-Hz cardiac respiratory cycles are coupled with electrical activity rather than with mechanical activity, that calcium oscillations drive a mitochondrial respiration cycle, that the pharmaceutical or genetic inhibition of electro-mitochondrial coupling results in arrhythmogenic behaviour, and that the induction of arrythmia by the chemotherapeutic mitoxantrone can be partially reversed by the co-administration of metformin. Microphysiological cardiac systems may further facilitate the study of the mitochondrial dynamics of cardiac rhythms and advance the understanding of cardiac physiology.

Gene expression of glucose homeostasis in a pancreas-liver microphysiological system

Project description:Current research on metabolic disorders and diabetes relies on animal models because multi-organ diseases cannot be well studied with the standard in vitro assays. Here, we connect models of key metabolic organs, pancreas and liver, on a microfluidic chip to enable diabetes research in a human-based preclinical system. Aided by mechanistic mathematical modelling, we show that hyperglycemia and high cortisone induce glucose dysregulation in the pancreas-liver microphysiological system (MPS) mimicking a diabetic phenotype seen in patients with glucocorticoid-induced diabetes. In this diseased condition, pancreas-liver MPS displays beta-cell dysfunction, steatosis, elevated ketone-body secretion, increased glycogen storage, and upregulated gluconeogenic gene expression. In turn, a physiological culture condition rescues the glucose tolerance and beta cell function. This method was evaluated for repeatability in two laboratories and was effective in multiple pancreatic islet donors. The model also provides a platform to identify new therapeutic targets as demonstrated with a combined transcriptome and proteome analysis.

SARS-CoV-2-induced disruption of a vascular bed in a microphysiological system caused by type-I interferon from bronchial organoids

Project description:Blood vessels show various COVID-19-related conditions including thrombosis and cytokine propagation. Existing in vitro blood vessel models cannot represent the consequent changes in the vascular structure or determine the initial infection site, making it difficult to evaluate how epithelial and endothelial tissues are damaged. Here, we developed a microphysiological system (MPS) that co-culture the bronchial organoids and the vascular bed to analyze infection site and interactions. In this system, virus-infected organoids caused damage in vascular structure. However, vasculature was not damaged or infected when the virus was directly introduced to vascular bed. The knockout of interferon-related genes and inhibition of the JAK/STAT pathway reduced the vascular damage, indicating the protective effect of interferon response suppression. The results demonstrate selective infection of bronchial epithelial cells and vascular damage by cytokines and also indicate the applicability of MPS to investigate how the infection influences vascular structure and functions.
