摘要:
Methods of inducing formation of functional and organized lymphatic vessels are described. Specifically, the methods relate to using Tie2 agonists to induce formation of functional and organized lymphatic vessels. The methods also relate to treating defects, diseases, and disorders characterized by lymphatic vessel malfunction, disorganization, and damage.

摘要:
Methods of creating mutations in genomic exons by inserting introns into the genomic exons via homologous recombination. Also, methods are provided for introducing modifications into genomic exons by inserting introns into the genomic exons via homologous recombination such that a mature mRNA transcript produced from a genomic region of the genome comprising the genomic exon does not contain the modification are provided. The methods provide for a rapid method for introducing mutations and/or modifications of any type into a mammalian cell genome.
摘要:
A method of reducing or preventing hypertension associated with administration of a vascular endothelial growth factor (VEGF) antagonist in a human subjects suffering from a disease or condition treatable with a VEGF antagonist in which is it desirable to reduce or prevent hypertension. The method is particularly useful for treatment of patients unresponsive to treatment with a VEGF inhibitor administered intravenously.
摘要:
A method of detecting and isolating cells that produce any secreted protein of interest (POI), comprising: a) constructing a cell line transiently or stably expressing a cell surface capture molecule, which binds the POI, by transfecting the cell line with a nucleic acid that encodes such cell surface capture molecule; b) transfecting said cell simultaneously or subsequently with a second nucleic acid that encodes a POI wherein such POI is secreted; c) detecting the surface-displayed POI by contacting the cells with a detection molecule, which binds the POI; and d) isolating cells based on the detection molecule.
摘要:
A method for engineering and utilizing large DNA vectors to target, via homologous recombination, and modify, in any desirable fashion, endogenous genes and chromosomal loci in eukaryotic cells. These large DNA targeting vectors for eukaryotic cells, termed LTVECs, are derived from fragments of cloned genomic DNA larger than those typically used by other approaches intended to perform homologous targeting in eukaryotic cells. Also provided is a rapid and convenient method of detecting eukaryotic cells in which the LTVEC has correctly targeted and modified the desired endogenous genes(s) or chromosomal locus (loci) as well as the use of these cells to generate organisms bearing the genetic modification.
摘要:
The present invention provides a method of achieving very high targeting efficiency by utilizing targeting vectors that utilize promoter-less selection cassettes and which are engineered to targeted into transcriptionally active loci. In particular, the invention provides a method for targeting promoter-less selection cassettes into transcriptionally active loci in stem cells or other eukaryotic cells with much greater efficiency than previously observed with other methods, thus reducing the number of drug-resistant clones to be screened or eliminating the need to screen for targeted cells altogether. The invention also encompasses the DNA targeting vectors, the targeted cells, as well as non-human organisms, especially mice, created from the targeted cells.
摘要:
The present invention provides for a modified TIE-2 ligand 2 which has been altered by addition, deletion or substitution of one or more amino acids, or by way of tagging, with for example, the Fc portion of human IgG-1, but which retains its ability to bind the TIE-2 receptor.
摘要:
High affinity fusion proteins (“trapbodies”), capable of binding and inhibiting the activity of soluble, interacting proteins (“SIPs”) are described. The trapbodies are multimers, preferably dimers, of SIP-specific fusion polypeptides which comprise SIP binding domains derived from SIP targets and/or anti-SIP immunoglobulins, as well as multimerizing components.
