    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 use of late passage mesenchymal stem cells (MSCs) for treatment of cardiac disorders. Such late passage MSCs may be administered to the myocardium of a subject for induction of native cardiomyoctye proliferation and repair of cardiac tissue. Additionally, the late passage MSCs may be genetically engineered to express a gene encoding a physiologically active protein of interest and/or may be incorporated with small molecules for delivery to adjacent target cells through gap junctions. The late passage MSCs of the invention may be used to provide biological pacemaker activity and/or provide a bypass bridge in the heart of a subject afflicted with a cardiac rhythm disorder. The biological pacemaker activity and/or bypass bridge may be provided to the subject either alone or in tandem with an electronic pacemaker.

    摘要: This invention provides for a chamber and system designed for use in assaying drug effects on heart rate. The chamber consists of a series of wells, each 3 mm by 3 mm in inner diameter. Cardiac myocytes disaggregated from neonatal animals are plated onto the bottom of each well and grown under standard tissue culture conditions. The chamber holds from 24-96 such wells. When drugs are to be assayed, the cells in each well are loaded with a calcium sensitive dye and the beating rate in each is monitored with a photodiode. Drug is added in graded concentrations to each well, and equilibrated and effects on rate are observed. This construct permits use of a cell based bioassay for the study of drugs or agents that may alter cardiac rate. This invention can be used in high throughput screening of drugs to evaluate/predict their effects on cardiac rate and rhythm. Further provided for by this invention is a vector which comprises a compound which encodes an ion channel.
