  • Encapsulated cell indicator system
    Publication number: 20080145860
    Abstract: The invention features an encapsulated cell indicator system that includes (a) indicator cells having a signal-responsive element operably linked to a reporter gene; (b) encapsulating material; and (c) a permeable membrane. In this encapsulated cell indicator system, the indicator cells are encapsulated in the encapsulated material and the encapsulated material and the indicator cells are surrounded by the permeable membrane.

  • Methods and reagents for cell transplantation
    Publication number: 20030031651
    Abstract: The invention features methods for producing cells for transplantation into myocardial tissue of a mammal (e.g., a human). The method includes the steps of (a) providing a population of bone marrow stem cells; (b) culturing the cells under conditions that induce the cells to become cardiomyogenic cells; (c) monitoring the state of differentiation of the cells of step (b); and (d) collecting the cells of step (b) when at least about 10% and as many as 100% of the cells are cardiomyogenic cells. The bone marrow stem cells can be, for example, human bone marrow stem cells. In one embodiment, the method includes the step of transplanting the differentiated stem cells into a mammal (e.g., a human).
