    摘要： The present invention provides for a method for preparing antibodies that specifically detect the type IV collagen .alpha.5 chain that is defective in various basement membrane disorders such as in X chromosome-linked Alport's syndrome. The invention further provides for the use of such antibodies to detect the .alpha.5(IV) collagen chain in solutions and other human tissue specimens using immunological methods comprised of antibodies specific for said protein. Along this line, the invention relates to the use of the specific antibodies to examine the presence or absence of the .alpha.5(IV) collagen chain in the tissues, e.g. skin or kidneys, etc. of patients with renal failure, possibly due to Alport's syndrome. In addition, a further object of the present invention is to provide compositions, comprising both labeled and unlabeled peptides containing sequences from the .alpha.5(IV) chain antigen (either as single peptides or conjugated to a carrier molecule or matrix) or labeled or unlabeled antibodies to said .alpha.5(IV) collagen chain or peptides containing sequence specific for the said polypeptide chain, and the use of the compositions for the diagnosis of basement membrane disorders, such as Alport's syndrome.

    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： 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.
