  • Method and system for in vitro developmental toxicity testing
    Patent number: 9958433
    Abstract: A method and system of in vitro developmental toxicity testing comprising the steps of micropatterning an extracellular matrix; growing embryonic stem cells on the micropatterned extracellular matrix in the presence of mesoendodermal induction and testing for change of the geometrical mesoendoderm structure in the presence or absence of a test compound wherein (1) a decrease in mesoendodermal differentiation and/or (2) a change in morphology of the geometrical mesoendoderm structure in the presence of the test compound compared to cells in the absence of the test compound indicates that the test compound is a developmental toxic agent.
    Type: Grant
    Filed: September 30, 2013
    Date of Patent: May 1, 2018
    Assignee: Agency for Science, Technology and Research
    Inventors: Hanry Yu, Yi-Chin Toh, Jiangwa Xing
