Abstract: An application-centric continuous delivery (ACCID) architecture provides a service that automates the configuration and management of end-to-end application lifecycle management (ALM) tools, through an innovative application-centric metadata model that can be customized through a self-service portal. With the ACCID architecture, IT organizations can provide version management, build automation, test automation, artifact management, infrastructure build, and automated application deployment that is consistent with global IT policy and governance and delivered as a service to organizations. The ACCID architecture references customized application metadata models that describe the application services, ALM requirements, and target infrastructure, to employ end-to-end automation of: the software deployment lifecycle and promotion across application environments, e.g., Development, Test, Pre-Production, and Production environments, using private, public, or hybrid cloud deployment models.

Abstract: The present invention generally relates to the field of cell growth and tissue engineering, in particular, tissue engineered compositions comprising a nanotextured substrate which is structurally configured for growth of cells in an anatomically correct adult phenotype in vitro. In particular, described herein are nanotextured substrates which are structurally configured for the anisotropic organization, maturation, and growth of in vitro-differentiated muscle cells, such as cardiomyocytes, and methods for the production and use thereof in varying sizes, nanotextures and substrate rigidities. In vitro-differentiated cardiomyocytes grown on the nanotextured substrates described herein are better-differentiated and more closely mimic adult cardiac tissue than the same cells grown on a non-textured substrate of the same composition.

Abstract: Compositions and methods for improving cardiac function, myocardial contractility and relaxation in a mammal are provided. Cardiomyocytes transfected with one or more expression vectors comprising a ribonucleotide reductase subunit R1-encoding nucleic acid sequence and a ribonucleotide reductase subunit R2-encoding nucleic acid sequence operably linked to a promoter are grafted to a mammalian myocardium. Also provided are compositions and methods for delivering dATP to a myocardium through grafting of donor cells overexpressing R1 and R2. dATP is thereby produced in situ and delivered through gap junctions established between donor cells and host cardiomyocytes. Alternatively, viral vector(s) having the R1 and R2-encoding construct(s) are administered to the mammal directly. Improvement of cardiac function can also be effected by administration of vectors comprising a nucleic acid sequence encoding a L48Q, 61 Q, or L57Q cTnC variant.

Abstract: The present invention relates to the devices and method comprising microelectrode arrays for the differentiation, maturation and functional analysis of electroconductive cells, including muscle cells (including, but not limited to, cardiomyocytes, skeletal muscle myocytes and smooth muscle myocytes) and neuronal cells. The microelectrode present on the arrays can be used to stimulate and record from cells cultured on the substrate. In some embodiments, the substrate has a substantially smooth surface, and in other embodiments the substrate is nanotextured, including an array of substantially parallel grooves and ridges of nanometer-micrometer widths.

Abstract: The present invention is directed to methods of producing cardiomyocytes having a nodal/pacemaker phenotype and cardiomyocytes having an atrial/ventricular phenotype. Isolated populations of nodal/pacemaker and atrial/ventricular cardiomyocytes are also disclosed. Methods of treating a subject having cardiac arrhythmia and a subject in need of cardiac tissue repair using the isolated populations of nodal/pacemaker cardiomyocytes and atrial/ventricular cardiomyocytes, respectively, are also disclosed.

Abstract: The survival of cells during transplantation is enhanced. Cells to be transplanted are administered in a formulation that provides two ore more survival enhancing factors. Optionally, prior to administration, the cells are cultured in the presence of factors that enhance survival, and may be heat shocked prior to transplantation.

Abstract: Viable differentiating cells from in vitro cultures of stem cells are selected for by partial dissociation to provide cell aggregates. Aggregates comprising cells of interest are selected for phenotypic features using methods that substantially maintain the cell to cell contacts in the aggregate.
