Evaluation of novel high-throughput embryonic stem cell tests with new molecular markers for screening embryotoxic chemicals in vitro.
The embryonic stem cell test (EST) is a validated in vitro alternative test for prediction of embryotoxicity with inhibition of cardiomyocyte differentiation under the microscope as beating areas at day 10 as an endpoint. However, improvements are necessary for regulatory acceptance and application to high-throughput screening. We have previously reported that heart and neural crest derivatives...
متن کاملDevelopment of a testing strategy for detecting embryotoxic hazards of chemicals in vitro by using embryonic stem cell models.
The importance of developing in vitro tests for embryotoxicity is discussed, and ECVAM's work with its collaborators is summarised. Studies are in progress to find new endpoints for use in the scientifically validated embryonic stem (ES) cell test, so that the potential for chemical effects on endodermal, mesodermal and/or ectodermal differentiation can be identified. This involves, inter alia,...
متن کاملScreening for novel regulators of embryonic stem cell identity.
Two recent studies, including one in this issue of Cell Stem Cell, have identified novel regulators of embryonic stem cell (ESC) self-renewal using genome-wide RNAi screens in mouse ESCs (Ding et al., 2009; Hu et al., 2009) and have further expanded the repertoire of factors that regulate ESC identity.
متن کاملDevelopment of a screening assay to identify teratogenic and embryotoxic chemicals using the zebrafish embryo.
We developed and optimized a screening procedure, in which zebrafish embryos were explored as a model for the evaluation of the specific embryotoxic and teratogenic potential of chemicals. A selection of known positive (retinoic acid, valproic acid, caffeine, lithium chloride) and negative (glucose, saccharin) compounds for developmental toxicity were used to evaluate this method. We exposed em...
متن کاملDifferentiation of Mouse Embryonic Stem Cell into Insulin-Secreting Cell
Purpose: Differentiation of mouse embryonic stem cells into Insulin secreting endocrine cells. Materials and Methods: In this study, Royan B1 mouse embryonic stem cell (derived from C57BL/6 mouse) were used. In directed differentiation method, embryonicstem cells after embryoid bodies formation were differentiated into insulin secreting cells. Nestin positive cells were obtained after culture ...
