  • Patent number: 12091650
    Abstract: The invention relates to culturing brain endothelial cells, and optionally astrocytes and neurons in a fluidic device under conditions whereby the cells mimic the structure and function of the blood brain barrier. Culture of such cells in a microfluidic device, whether alone or in combination with other cells, drives maturation and/or differentiation further than existing systems.
    Type: Grant

    Date of Patent: September 17, 2024
    Assignee: EMULATE, INC.

  • Patent number: 11981918
    Abstract: Induced Pluripotent Stem Cell (Ipsc) technology enables the generation and study of living brain tissue relevant to Parkinson's disease (PD) ex vivo. Utilizing cell lines from PD patients presents a powerful discovery system that links cellular phenotypes observed in vitro with real clinical data. Differentiating patient-derived iPSCs towards a dopaminergic (DA) neural fate revealed that these cells exhibit molecular and functional properties of DA neurons in vitro that are observed to significantly degenerate in the substantia nigra of PD patients. Clinical symptoms that drive the generation of other relevant cell types may also yield novel PD-specific phenotypes in vitro that have the potential to lead to new therapeutic avenues for patients with PD.

  • Publication number: 20230333092
    Abstract: Described herein are the effects of continuous media perfusion on SC-Chips and the observed activation of pronounced neural tissue growth and vascular recruitment into the neural tissue channel. ALS patient chip overexpression of known neurodegenerative disease biomarkers neurogranin and neurofilament family members are also described and utilized for the invention.

  • Publication number: 20230159896
    Abstract: Described herein is a human, cardiovascular platform for assessing cardiotoxicity of novel/existing chemotherapeutic agents that takes advantage of microfluidic organ chip systems to examine interaction between hiPSC-derived cardiovascular cells in an integrated system. Human induced pluripotent stem cell derived cardiomyocytes (hiPSC-CMs) and human induced pluripotent stem cell derived endothelial cells (hiPSC-ECs) can serve as an in-vitro platform for assessing disease pathology, including infectious disease, evaluate drug efficacy, toxicity, cardiotoxicity and cardioprotection. This includes evaluating VEGFR2/PDGFR-inhibiting tyrosine kinase inhibitors and drug efficacy in a viral infection model, including coronaviruses. They are scalable, functionally-active cell types that mimic the cells comprising the myocardium and systemic vasculature.

  • Patent number: 11039610
    Abstract: Brain microvascular endothelial cells (BMECS) can be generated from pluripotent stem cells, and possess membrane barrier functions along with capability for maturation into other developing tissues. This cell type has not been successfully frozen with loss of significant viability and/or BMEC functional properties. For example, BMECs can be used to model barrier function in blood brain barrier, by calculating the trans-endothelial resistance (TEER). However, thawed primary BMECs lose TEER resistance. By optimizing cell preparation, freezing media selection, and the controlled freezing, the Inventors have achieved complete recovery of frozen cells, achieving proper tight junction protein expression and physiologically relevant TEER. The freezing methods and compositions described herein, thereby allow for BMECs to be manufactured, frozen and distributed at scale.

  • Publication number: 20210130774
    Abstract: Described herein is a microphysiological system for models of disease. Specifically, induced pluripotent stem cells (iPSCs) and iPSC-derived cells, including those obtained from disease patients, are seeded onto microfluidic “chip” devices to study cellular development and disease pathogenesis. Herein, neurodegenerative disease modeling, including Parkinson's Disease (PD) is shown to reproduce key PD pathology in a vascularized human model that contains neurons relating to PD pathology. Such compositions and methods are used for research for PD biomarkers, patient screening for PD risk assessment, and therapeutic discovery and testing. A panel of biomarkers are generated through analysis of living PD-chips by neural activity, whole transcriptomic, proteomic, and metabolomic analysis, and functional enzyme tests of media and tissue.
