Method for Reproducible Differentiation of Clinical Grade Retinal Pigment Epithelium Cells

The retinal pigment epithelium (RPE) is a cell monolayer with specialized functions crucial to maintaining the metabolic environment and chemistry of the sub-retinal and choroidal layers in the eye. Damage or disease causing RPE cell loss leads to progressive photoreceptor damage and impaired vision. Loss of RPE is observed in many of the most prevalent cases of vision loss, including age related macular degeneration (AMD) and Best disease.

Methods of Inducing Deacetylase Inhibitors to Promote Cell Differentiation and Regeneration

The present invention discloses a method of enhancing progenitor cell differentiation, including enhancing myogenesis, neurogenesis and hematopoiesis, by contacting a progenitor cell with an effective amount of a deacetylase inhibitor (DI). The progenitor cell can be part of cell culture, such as a cell culture used for in vitro or in vivo analysis of progenitor cell differentiation, or can be part of an organism, such as a human or other mammal.

Signal Transduction Inhibitors Of Allergic Reactions

Allergic reactions affect nearly 40 million persons in the United States. Allergic reactions are due to a sequential interaction beginning with the extracellular aggregation of the high affinity receptor for IgE (FcepsilonRI) followed by intracellular tyrosine phosphorylation which initiates a further cascade of events eventually leading to histamine and cytokine release. The reaction is initiated by Lyn kinase which is pre-associated with the FcepsilonRI.

Calorimeter And Method For Simultaneous Measurement Of Thermal Conductivity And Specific Heat Of Fluids

The present invention is a novel calorimeter and calorimetry apparatus and method for the ultrasensitive simultaneous measurement of heat capacity and thermal conductivity of fluids. The unique simultaneous measurement of the two parameters avoids sources of error seen in other methods. The calorimeter shows excellent accuracy of 1 part in 10,000 and run-to-run variability of 1 part in 100,000, as well as excellent long-term reproducibility.

Chimeric Antibodies Against Hepatitis B e-Antigen

The invention relates to recombinant chimeric rabbit/human monoclonal antibody fragments (Fabs) against hepatitis B Virus e-antigen (HBeAg), notably Fab me6. Viral hepatitis is the seventh leading cause of death worldwide. Hepatitis B core antigen (HBcAg) forms an icosahedral structure containing the viral genome. Both the HBcAg and the HBeAg of interest here are expressed by two different start codons of the viral C gene. Unlike the related HBcAg which activates type 1 T helper (Th1) cells leading to immune attack, the HBeAg activates Th2 cells which promote immune tolerance.

Engineering Neural Stem Cells Using Homologous Recombination

Methods for modifying the genome of a Neural Stem Cell (NSC) are disclosed. Also, methods for differentiating NSCs into neurons and glia are described. NSCs are multipotent, self-renewing cells found in the central nervous system, capable of differentiating into neurons and glia. NSCs can be generated efficiently from pluripotent stem cells (PSCs) and have the capacity to differentiate into any neuronal or glial cell type of the central nervous system.

Compositions for Modification of Genomic DNA and Exogenous Gene Expression

A novel method of targeted insertion of transgenes at CLYBL locus directly in human cells is disclosed. Also, methods and compositions for increasing targeted insertion of a transgene into a specific location within the cell or increasing the frequency of gene modification in a targeted locus are disclosed. Genome modification by precise gene targeting at specific sequence/locus has great advantages over conventional transient expression or random integration methodologies and, therefore, has tremendous therapeutic potential.

Human iPSC-Derived Mesodermal Precursor Cells and Differentiated Cells

Cells, cell culture methods, and cell culture media compositions useful for producing and maintaining iPSC-derived cell lines that are of higher purity and maintain cell type integrity better than current iPSC-derived cell lines are disclosed. Human induced pluripotent stem cells (hiPSCs) can be generated by reprogramming somatic cells by the expression of four transcription factors. The hiPSCs exhibit similar properties to human embryonic stem cells, including the ability to self-renew and differentiate into all three embryonic germ layers: ectoderm, endoderm, or mesoderm.
