| Outline of Final Research Achievements |
To understand the mechanisms underlying craniofacial development, we promoted cell differentiation of human pluripotent stem cells (hPSCs) into ectoderm, neural epithelium, and anterior neural crest. At first, we have provided evidence that fibroblast growth factor-2 and Activin A synergistically regulated the initiation of hPSC differentiation into neural cell lineages even though hPSCs autonomously differentiate into neural cell lineages. Further, we developed a differentiation protocol for anterior neural crest induction using several growth factors and inhibitors, suggesting the mechanisms underlying craniofacial development.
