摘要:
The present invention relates to methods for decreasing or inhibiting disorders associated with vascular hyperpermeability and to methods of screening for compounds that affect permeability, angiogenesis and stabilize tight junctions. In one aspect of the present invention there is provided a method of decreasing or inhibiting vascular hyperpermeability in an individual in need of such treatment. The method includes administering to the individual an effective amount of an antiangiogenic compound selected from the group consisting of endostatin, thrombospondin, angiostatin, tumstatin, arrestin, recombinant EPO and polymer conjugated TNP-470. Other antiangiogenic compounds are disclosed herein.
摘要:
The invention is directed to compositions and methods for preparing electrospun matrices comprising at least one natural biological material component and at least one synthetic polymer material. The natural component makes the matrices highly biocompatible while the molecular weight polymer component can impart additional strength mechanical strength to the scaffold and/or improve ease of manufacture by increasing viscosity and spinning characteristics of the solution during electrospining.
摘要:
A method of treating diabetes in a mammalian subject is carried out by: (a) providing mammalian amniotic fluid stem cells, and then (b) administering the cells to the subject in an amount effective to treat diabetes. Optionally, the cells may be differentiated into pancreatic-like cells or at least treated to initiate subsequent differentiation into-pancreatic-like cells, prior to administration.
摘要:
The present invention concerns methods of screening cells for differentiation or de-differentiation, and/or for status as a pluripotent or multipotent (e.g., “stem”) cell, by detecting the differential expression (e.g., upregulation, downregulation) of genes.
摘要:
Provided herein are methods for determining ethanol exposure of a prenatal subject, including measuring whether or not amniotic fluid stem cells collected from amniotic fluid surrounding the prenatal subject have a upregulation or expression of one or more genes of a first predetermined combination and/or a downregulation of expression of one or more genes of a second predetermined combination. Also provided are methods for determining ethanol exposure of a prenatal subject which methods include measuring alkaline phosphatase activity and/or calcium deposition of amniotic fluid stem cells collected from amniotic fluid surrounding the prenatal subject.
