Stem Cells in Predictive Toxicology

Predictive toxicology is the evaluation of chemicals that result in the adverse effects to human health. We develop toxicology models with embryonic stem cells to determine teratogenic and somatic toxicity of chemicals and drugs during early development and adulthood.

Preclinical Safety

Epigenetics has a determinant role in cellular differentiation and placity. Our laboratory studies epigenetics during hESC differentiation and how it affect tumorogenesis.

Laser capture microscopy of stem cells

Heterogeneity is a limitation to the generation of enriched cells from ES cells for in vitro models of disease. In pioneer studies, we have shown that photonics application enable the isolation and enrichment of ES-cell derived cell types.
