Abstract: Certain donor plasmid vectors such as pFastBac™1 and pFastBac™ Dual lack a cis DNA element upstream of the polh translation start codon (ATG) present in wild type (wt) Autographa californica multiple nucleopolyhedrovirus (AcMNPV), and contain a SV40 pA fragment. When a cis DNA element is inserted upstream of the 50 bp polh promoter and SV40 pA was replaced with a AcMNPV polh pA signal in pFastBac™1 and pFastBac™Dual, certain protein expression levels in High Five™ cells using the Bac-to-Bac® system reached that of the wt AcMNPV.
Abstract: The electrical pacemakers currently being used for the therapeutic approaches for treatment of “sick sinus syndrome” are not hormonally regulatable and entail risks through infections or premature battery discharge. These problems could be overcome by means of “biological cardiac pacemakers” obtained from pluripotent stem cells (PSCs). It has been shown that the controlled differentiation of stem cells with TBX, inductors of sinoatrial node cells, and an additional Myh6 promoter-specific antibiotic selection can give cardiomyocyte aggregates consisting to an extent of more than 80% of physiologically functional pacemaker cells. These induced sinoatrial bodies (“iSABs”) for the first time exhibited very high beat frequencies (300-400 bpm), similar to those in a murine heart, and were able to stably rhythmically stimulate heart muscle cells ex vivo.
Abstract: Described are nucleic acid regulatory elements that are able to enhance liver-specific expression of genes, methods employing these regulatory elements and uses of these elements. Expression cassettes and vectors containing these nucleic acid regulatory elements are also disclosed. These are particularly useful for applications using gene therapy.

Abstract: In certain aspects, the present invention provides methods for inducing a stable gene modification of a target nucleic acid via homologous recombination in a primary cell, such as a primary blood cell and/or a primary mesenchymal cell. In certain other aspects, the present invention provides methods for enriching a population of genetically modified primary cells having targeted integration at a target nucleic acid. The methods of the present invention rely on the introduction of a DNA nuclease such as a Cas polypeptide and a homologous donor adeno-associated viral (AAV) vector into the primary cell to mediate targeted integration of the target nucleic acid. Also provided herein are methods for preventing or treating a disease in a subject in need thereof by administering to the subject any of the genetically modified primary cells or pharmaceutical compositions described herein to prevent the disease or ameliorate one or more symptoms of the disease.
