    Abstract: The present invention relates to the field of mammalian cell culture, and provides methods and compositions for cell attachment to, cultivation on and detachment from a solid substrate surface containing from at least about 0.5% N, a sum of O and N of greater than or equal to 17.2% and a contact angle of at least about 13.9 degrees, lacking a feeder cell layer and lacking an adlayer. In one embodiment of the present invention, the cells are treated with a compound capable of inhibiting Rho kinase activity. In another embodiment, the cells are treated with a compound capable of inhibiting Rho activity.

    Abstract: The present invention is directed to methods to differentiate pluripotent stem cells. In particular, the present invention provides methods of characterization of cells differentiated into cells expressing markers characteristic of the pancreatic endocrine lineage utilizing unique surface markers. The present invention also provides methods to enrich or sort cells expressing markers characteristic of the pancreatic endocrine lineage. The present invention also provides methods to deplete cells that may contaminate populations of cells expressing markers characteristic of the pancreatic endocrine lineage formed by the methods of the present invention, thereby reducing the incidence of tumor formation in vivo following transplantation.
