摘要:
The present disclosure is directed to the development of compositions, such as extracellular matrices, and processes for using the same, that both maintain stem cells in vitro pluripotency and enable self-renewal. In this regard, it has been discovered that when pluripotent mouse and human embryonic stem cells are cultured on plates coated with recombinant laminin-10 (laminin-511) or their functional domains, in the absence of differentiation inhibitors or feeder cells, the embryonic stem cells proliferated and maintained their pluripotency.
摘要:
Novel peptides that specifically bind the γ2 chain of laminin-5 and other γ2-associated proteins; related compositions (e.g., derivatives and variants of such peptides; nucleic acids comprising sequences encoding such peptides; pharmaceutical compositions comprising either of such molecules; etc.); methods of using the same for diagnostic, prophylactic, and therapeutic purposes; and additional new and useful related compositions and methods are provided.
摘要:
The instant invention provides for apparatus and methods for the efficient administration of pharmaceuticals to target cells, tissues and/or organs, for a variety of functional uses.
摘要:
The present invention provides substantially purified laminin 8, methods for making recombinant laminin 8, cells that express recombinant laminin 8, and methods for using the recombinant laminin 8 to accelerate the healing of injuries to vascular tissue and tissue of mesenchymal origin, and to promote cell attachment and migration.
摘要:
The present invention relates to a method for isolating and identifying the nucleotide sequence of the human gene for the type IV collagen &agr;5(IV) chain. The present invention is directed to the determination of the nucleotide sequence of the gene for the &agr;5(IV) collagen chain in individuals by any method known to the art, e.g. cloning from genomic DNA libraries or amplifying gene regions with the polymerase chain reaction (PCR) and studying their physical properties or nucleotide sequences. In addition, the invention is directed to the use of the nucleotide sequences of the &agr;5(IV) gene to amplify or identify the nucleotide sequences of the &agr;5(IV) gene.
摘要:
The present invention provides for a method for isolating and partially characterizing the nucleotide sequence for a novel polypeptide chain of human basement membrane (type IV) collagen, referred to as the .alpha.5(IV) polypeptide chain. The invention provides for the use of the identified nucleotide sequence (or DNA fragments thereof) to detect mutations in individual genes specific for the .alpha.5(IV) chain which can, directly or indirectly, produce several human diseases. Moreover, the invention also relates to procedures for determining genetic or acquired disorders of basement membranes using the identified nucleotide sequence (or DNA fragments thereof) of the .alpha.5(IV) polypeptide chain, probes specific to DNA fragments of said nucleotide sequence,or antibodies to the nucleotide sequence or DNA parts thereof. Also, the invention relates to the use of gene fragments generated through amplification from human genomic or cloned DNA for detection and analysis of the gene, such as in detection of mutations.
摘要:
Basement membrane collagen degrading enzymes are provided which are useful for the detection of malignant cells with metastatic activity. Means for detecting such cells are also provided.
摘要:
Antibodies against various domains of laminin-332 are discussed herein. The antibodies reduce the adhesion and matrix binding properties of laminin-332, inhibiting tumor growth and metastasis in vivo. Pharmaceutical compositions and methods of using the antibodies for diagnostic, prophylactic, and/or therapeutic purposes are disclosed.
摘要:
Compositions and processes for culturing human stem cells in vitro in an undifferentiated state are disclosed. In this regard, human embryonic stem cells proliferated and maintained their pluripotency when cultured on plates coated with recombinant laminin-10 (laminin-511).
