Human pluripotent stem cells (hPSCs) have the potential to fundamentally change the way that we go about treating and understanding human disease. Despite this extraordinary potential, these cells also have an innate capability to form tumors in immunocompromised individuals when they are introduced in their pluripotent state. Although current therapeutic strategies involve transplantation of only differentiated hPSC derivatives, there is still a concern that transplanted cell populations could contain a small percentage of cells that are not fully differentiated. In addition, these cells have been frequently reported to acquire genetic alterations that, in some cases, are associated with certain types of human cancers. Here, we try to separate the panic from reality and rationally evaluate the true tumorigenic potential of these cells. We also discuss a recent study examining the effect of culture conditions on the genetic integrity of hPSCs. Finally, we present a set of sensible guidelines for minimizing the tumorigenic potential of hPSC-derived cells. © 2016 The Authors.

The present invention relates to the seminal discovery of compositions and a method of producing NSC obtained from stem cells derived from parthenogenically activated human oocytes (phNSC). The phNSC of the invention maintain proliferative and differentiation potential during cultivation and expansion.

The disclosure provides methods for isolating a pure or enriched population of differentiated cells derived from stem cells, comprising differentiating the population of stem cells; and migrating the differentiated cells through a porous membrane in a differentiation device to isolate the pure or enriched population of differentiated cells. The disclosure also provides a differentiation device for isolating a pure or enriched population of differentiated cells derived from stem cells, the device comprising a porous membrane; and an extracellular matrix.
