Astrocyte Differentiation of Neural Stem Cells with StemPro Embryonic Stem Cell Serum Free Medium for Research and Potential Therapeutic Use

This technology includes an innovative method for differentiating astrocytes from neural stem cells (NSCs). The process involves using Life Technologies StemPro embryonic stem cell serum-free medium to initially guide NSCs towards a neuronal lineage. Over a period of 28-35 days, as the cells are continually passaged, neurons gradually die off, leading to the proliferation of astrocytes. By the end of this differentiation protocol, approximately 70% of the cells exhibit markers characteristic of mature astrocytes, specifically GFAP.

Generation of Gene Specific Targeting Donor Plasmid (p5KI-GP-CHN and p3KI-GP-CHN)

This technology includes the use of engineered human induced pluripotent stem cells (iPSCs) for various applications such as studying cell differentiation, drug screening, and gene transfer therapy. It employs gene targeting donors flanked by DNA sequences compatible with endogenous loci to integrate transgenes through homologous recombination. A key aspect is the flexible gene targeting donor design, used in conjunction with safe harbor transcription activator-like effector nucleases (TALENs).

Generation of Safe-harbor Gene Targeting Donor Plasmids

This technology includes two safe harbor gene targeting donors, specifically designed for applications in the study of induced pluripotent stem cells (iPSC). These include the pAAVS1D-CMV.RFP-EF1a.copGFPpuro and pAAVS1-iCLHN donors. A key feature of these donors is their ability to integrate various transgenes into specific loci through homologous recombination, facilitated by sequences homologous to safe harbor loci. When paired with TALENs targeting these loci, these plasmids enable precise and efficient genome engineering in human cells.

Generation of AAVS1 and C13 “Safe Harbor” Transcription Activator-life Effector Nucleases (TALENs) for Drug Screening or Gene Therapy Development

This technology includes AAVS1 and C13 “safe harbor” transcription activator-life effector nucleases (TALENs) for drug screening or gene therapy applications. TALENs are engineered sequence-specific DNA endonucleases that can significantly enhance genome-editing efficiency by >100-1000 folds. “Safe harbor” such as AAVS1 safe harbor and C13 safe harbor is genome locus that allows robust and persistent transgene expression with no or minimal interference of endogenous gene expression and cell properties.

Compositions and Methods for Reducing Serum Triglycerides

This technology includes a vaccine for lowering plasma triglycerides by inducing the formation of autoantibodies against either ANGPTL3 or ANGPTL4, which are inhibitors of Lipoprotein Lipase. This was done by conjugating synthetic peptides based on ANGPTL3 or ANGPTL4 to virus- like particles (VLPS). Injection of the vaccine in animal models was shown to induce the autoantibody against the target and to lower plasma triglycerides.

Novel ApoC-11 Mimetic Peptides That Activate LPL for the Treatment of ApoC-11 Deficiency and Hypertriglyceridemia

This technology includes a new class of synthetic peptides that activate Lipoprotein Lipase (LPL), a key plasma enzyme that lowers triglycerides. Mutations in apoC-II is a genetic cause of severe hypertriglyceridemia, which can lead to cardiovascular disease and pancreatitis.

Mouse Models of Cryopyrin-Associated Periodic Syndrome (CAPS) for Drug Discovery

This technology includes mouse models that express versions of mouse cryopyrin protein containing mutations associated with human CAPS disease. We engineered mutations associated with three specific CAPS phenotypes (familial cold autoinflammatory syndrome (FCAS); Muckle-Wells syndrome (MWS); and neonatal onset multisystem inflammatory disease (NOMID)) into the mouse cryopyrin gene (called Nlrp3) to examine the roles of IL-1 β and related cytokines, and better characterize inflammasome functions.

Novel Methods for Reducing Inflammation and Treating Diseases such as Parkinson's and Alzheimer's Disease

Microglia activation leads to inflammation mediated dopaminergic degeneration in the brain of patients with Parkinson and Alzheimer's Disease. Thus Identification of drugs that reduce microglia activation could prevent or reverse neuronal degeneration in these diseases and other degenerative CNS disorders.
