    摘要： A device and method for analyzing cells includes a housing with a chamber, a barrier supported by a frame disposed within the chamber, and a plate arranged at a bottom surface of the housing interior of the chamber. The plate is adapted to receive and sustain cells and the barrier separates the plate into at least two contiguous separate areas. In some embodiments, a thin rubber strip is arranged at the bottom edge of the barrier, which facilitates control of the area in which each cell type is grown, the size of the gap between the cells, and helps prevents over growth of the two cell types on to each other.

    摘要： The present invention provides methods and compositions relating to the labeling of target cells with quantum dots (QDs). Specifically, a delivery system is disclosed based on the use of negatively charged QDs for delivery of a tracking fluorescent signal into the cytosol of target cells via a passive endocytosis-mediated delivery process. In a specific embodiment of the invention the target cell is a stem cell, preferably a mesenchymal stem cell (MSC). Such labeled MSCs provide a means for tracking the distribution and fate of MSCs that have been administered to a subject to promote cardiac repair. The invention is based on the discovery that MSCs can be tracked in vitro for up to at least 6 weeks. Additionally, QDs delivered in vivo can be tracked for up to at least 8 weeks, thereby permitting for the first time, the complete 3-D reconstruction of the locations of all MSCs following administration into a host.

    摘要： The present invention provides methods and compositions relating to the labeling of target cells with nanometer scale fluorescent semiconductors referred to as quantum dots (QDs). Specifically, a delivery system is disclosed based on the use of negatively charged QDs for delivery of a tracking fluorescent signal into the cytosol of target cells via a passive endocytosis-mediated delivery process. In a specific embodiment of the invention the target cell is a stem cell, preferably a mesenchymal stem cell (MSC). Such labeled MSCs provide a means for tracking the distribution and fate of MSCs that have been genetically engineered to express, for example, a hyperpolarization-activated cyclic nucleotide-gated (“HCN”) channel and administered to a subject to create a biological pacemaker. The invention is based on the discovery that MSCs can be tracked in vitro for up to at least 6 weeks. Additionally, QDs delivered in vivo can be tracked for up to at least 8 weeks, thereby permitting for the first time, the complete 3-D reconstruction of the locations of all MSCs following administration into a host.
