Methods and compositions related to dopaminergic neuronal cells

摘要

A method of differentiation stem cells cells by contacting stem cells with a dopaminergic differentiation agent is provided in certain aspects. For example, the agent may comprise substituted benzoxazole. These methods and compositions may be used in toxicological screens, e.g., to evaluate the neurotoxicity of a test compound or treatment of neurological disorders.

主权项

1. A method of enhancing differentiation of stem cells into dopaminergic neural cells comprising inducing neural cell differentiation of stem cells in the presence of zoxazolamine (Zol) or a structural analog of Zol having the capacity to stimulate potassium channels for a sufficient amount of time to differentiate the stem cells into dopaminergic neural cells, wherein said stem cells are pluripotent stem cells or neural stem cells and wherein the presence of Zol or said analog increases the number of dopaminergic neurons compared to inducing neural cell differentiation of pluripotent cells or neural stem cells in the absence of Zol or said analog.
