Described herein are methods and kits for the detection of platelet-activating pathogenic antibodies in samples from patients suspected of having platelet-activating antibodies or non-HIT anti-PF4 antibody mediated syndromes using platelets and polyvinyl sulfonate or salts thereof. Upon platelet activation, thrombospondin-1 (TSP1), a platelet granule protein, is released and can be detected using a TSP1 antigen capture enzyme linked immunosorbent assay (ELISA) to accurately measure platelet activation.

A method for the expression and / or for the amplification of the expression of thrombospondin-1, fibronectin, vimentin and / or mimecan in human skin. the method comprises applying to human skin at least one caviar extract which is capable of causing the expression and / or the amplification of the expression of thrombospondin-1, fibronectin, vimentin and / or mimecan in human skin.

The present invention provides a method for determining the quality of cultured corneal endothelial cells (CECs) comprising measuring in or on a cultured CEC a level of expression of the genes Thrombospondin-2 (THBS2) and / or Vitelline Membrane Outer Layer 1 Homolog (VMO1), and determining that the quality of said cultured CEC is non-therapy-grade if said measured level of expression corresponds to a THBS2+ and / or VMO1+ expression profile.

The invention further relates to compositions and methods for promoting tissue regeneration in a subject by administering a hydrogel composition including a decellularized extracellular matrix (ECM), wherein the ECM originates from a tissue lacking thrombospondin-2 (TSP2), and a HIF-la stabilizing compound. The invention further provides methods for preparing a hydrogel composition including a decellularized extracellular matrix (ECM), wherein the ECM originates from a tissue lacking thrombospondin-2 (TSP2), and a HIF-la stabilizing compound.

Described are various embodiments of anti-cancer polypeptides, nucleic acid constructs. and methods of using same, particularly for the expression of protein comprising three thrombospondin-1 type 1 repeats (3TSR), as well as pharmaceutical compositions comprising any of the disclosed polypeptides or nucleic acid constructs for the treatment of solid tumor cancers such as ovarian cancer or pancreatic cancer.

Provided herein are methods for purifying recombinant A Disintegrin-like and Metallopeptidase with Thrombospondin Type 1 Motif 13 (ADAMTS13) protein from a sample. The method comprises enriching for ADAMTS13 protein by chromatographically contacting the sample with hydroxyapatite under conditions that allow ADAMTS13 protein to appear in the eluate or supernatant from the hydroxylapatite. The methods may further comprise tandem chromatography with a mixed mode cation exchange / hydrophobic interaction resin that binds ADAMTS13 protein. Additional optional steps involve ultrafiltration / diafiltration, anion exchange chromatography, cation exchange chromatography, and viral inactivation. Also provided herein are methods for inactivating virus contaminants in protein samples, where the protein is immobilized on a support. Also provided herein are compositions of ADAMTS13 prepared according to said methods.

The present invention relates to recombinant proteins having an amino acid sequence corresponding to or related to the thrombospondin type 1 repeat homology domain of a member of the CCN family proteins and the use thereof. Furthermore, the present invention relates to fusion proteins comprising an amino acid sequence corresponding to or related to the thrombospondin type 1 repeat homology domain of a member of the CCN family proteins combined with a fusion partner and optionally a linker region. Also, novel protease resistant Fc-fragments are disclosed herein.

The disclosure provides a method for treating and / or preventing graft rejection with A Disintegrin And Metalloproteinase with Thrombospondin type 1 motif, member-13 (ADAMT S13). The disclosure provides a method for increasing ADAMTS13-mediated von Willebrand factor (VWF) cleavage in a subject that received a graft by administering ADAMTS13. The disclosure also provides a method of determining the likelihood that a subject will rejection a graft.

Disclosed is a method for diagnosing a patient's breast cancer (BC) health state, or change in BC health state, or for diagnosing risk of BC or the presence of BC in a patient, comprising detecting, in a plasma sample from said patient, one or more biomarker values that corresponds to thrombospondin-1 (THBS1) or a THBS1-containing complex structure by performing a capillary electrophoresis under non-reducing conditions, and assigning the patient as having or not having BC, or having or not having a change in BC health state, or having or not having a risk of BC based on said biomarker values.

The present invention relates to the role of ADAMTS12 protein (A Disintegrin And Metalloproteinase with ThromboSpondin motifs 12 protein) in the development of chronic kidney disease, in particular progressive chronic kidney disease and renal fibrosis. In particular, the present invention relates to methods for identifying compounds that bind to the ADAMTS12 protein and to the use of ADAMTS12 protein for screening and identifying ADAMTS12-interacting and ADAMTS12-inhibiting compounds. The present invention further relates to pharmaceutical compositions for use in the treatment of kidney diseases, in particular pharmaceutical compositions comprising active agents that bind to and / or inhibit the ADAMTS12 protein.

The disclosure concerns methods and kits of diagnosis of pancreatic cancer and monitoring disease burden in patients diagnosed with pancreatic cancer, the method comprising quantitative determination of the concentration of extracellular vesicles that are positive for one, two or three markers selected from thrombospondin-2 (THBS2), alkaline phosphatase placental-like 2 (ALPPL2), and macrophage migration inhibitory factor (MIF) in the patients' fluid samples.

A method for diagnosing a patient's breast cancer (BC) health state, or change in BC health state, or for diagnosing risk of BC or the presence of BC in a patient, comprises detecting, in a plasma sample from the patient, one or more biomarker values that correspond to thrombospondin- 1 (THBS1) or a THB SI -containing complex structure by performing a capillary electrophoresis under non-reducing conditions, and assigning the patient as having or not having BC, or having or not having a change in BC health state, or having or not having a risk of BC based on the biomarker values.
