The present invention provides new protease resistant polypeptides, as well as compositions and methods for treating, ameliorating or preventing conditions related to joint damage, including acute joint injury and arthritis.

Embodiments of the invention are directed to the administration of the composition containing a portion of the peptide Lv to a subject to promote angiogenesis. The interaction between peptide Lv and VEGFR2 represents a novel pathway regulating angiogenesis and cardiac function. The artificially modified peptide Lv, the inverso D-peptide Lv, shows a similar efficacy in promoting endothelial cell proliferation as the natural peptide Lv. Additional embodiments are directed to the use of anti-Lv antibodies for reducing angiogenesis and dampening L-VGCC activities.

The invention is directed to methods for the treatment of diseases and conditions caused by increased vascular permeability. The invention is also directed to methods for returning vascular permeability that is a symptom of a disease or condition to a homeostatic state. Specifically, the invention is directed to methods for the treatment of diseases and conditions caused by increased vascular permeability or returning vascular permeability that is a symptom of a disease or condition to a homeostatic state by administering to a subject suffering from such diseases and conditions and symptoms novel cellular factor-containing solution compositions (referred to herein as “CFS” compositions), including novel sustained-release cellular factor-containing solution compositions (referred to herein as “SR-CFS” compositions).

A trispecific inhibitor for treating cancer includes a first targeting domain having a binding specificity conferred by a VEGF binding antagonist; a second targeting domain having a binding specificity conferred by an immune checkpoint regulator binding antagonist; and a third targeting domain having a binding specificity conferred by a Tie2 tyrosine kinase receptor binding antagonist. The targeting domains may contain one or more antibody variable regions, peptide inhibitors, dominant negative proteins, small molecule drugs or combinations thereof.

A synthetic truncated norrin protein is provided. The synthetic truncated norrin protein is a −24 residue N-terminus norrin truncate relative to SEQ ID. NO. 1 that retains the cysteine-knot motif and frizzled-4 binding properties and has a mutation in the cysteine-knot motif in at least one position 81-90 of SEQ ID. NO. 1 that interferes with protease cleavage of the resulting protein thereby extending the biological half-life thereof in vivo relative to native norrin.

Cells derived from postpartum tissue and methods for their isolation and induction to differentiate to cells of a chondrogenic or osteogenic phenotype are provided by the invention. The invention further provides cultures and compositions of the postpartum-derived cells and products related thereto. The postpartum-derived cells of the invention and products related thereto have a plethora of uses, including but not limited to research, diagnostic, and therapeutic applications, for example, in the treatment of bone and cartilage conditions.
