A Mouse Model for Human Osteoarthritis

Read more about A Mouse Model for Human Osteoarthritis

Osteoarthritis (OA) is the most common form of arthritis and affects more than 20 million Americans, costing billions of dollars in health care annually. Osteoarthritis is caused by the breakdown of joint cartilage, leading to a loss of the cartilage "cushion" between the bones of the joints. Risk factors associated with OA include age, obesity, traumatic injury and overuse due to sports or occupational stresses. There is no cure for OA and current treatments are directed at the symptomatic relief of pain, and at improving and maintaining joint function.

WNT1-Induced Secreted Protein-1 Knockout Mouse Model

Read more about WNT1-Induced Secreted Protein-1 Knockout Mouse Model

WNT1-induced secreted protein-1 (WISP1) is expressed at high levels in osteoblasts and their precursors. WIPS1 plays an important role in various aspects of bone formation. Scientists at the NIH generated Wisp1-deficient (Wisp1^-/-) mice. Deletion of Wisp1 resulted in a decrease in bone mineral density, total bone volume, bone thickness, and biomechanical strength.

Regenerative Therapy for Cartilage Damage

Read more about Regenerative Therapy for Cartilage Damage

The subject technology discloses a tissue engineering method for treating cartilage damage. Stem cells from bone marrow are attached to a novel scaffold, hyaluronic acid-coated fibrin microbeads, and transferred to a live host to form cartilage. The regenerated cartilage is stable and not hypertrophic, which has been problematic in the current regenerative methods.

Micropatterning of Extracellular Matrix Proteins Using Microphoto-ablation Of Poly vinyl Alcohol (PVA) Monolayers

Read more about Micropatterning of Extracellular Matrix Proteins Using Microphoto-ablation Of Poly vinyl Alcohol (PVA) Monolayers

Available for licensure and commercial development is a micro-photoablation (µPA) method used as a micro-patterning technique to attach ECM proteins or other biological molecules to specified locations. Advantages of this photolytic technique are that it: (a) is stampless, (b) allows for flexible pattern generation to the submicron level, (c) allows for live cell fluorescence imaging, retains cell viability, and (d) allows the use of multiple proteins.

Antigen Mixtures for Serological Detection of HHV-8 Infection

Read more about Antigen Mixtures for Serological Detection of HHV-8 Infection

This invention describes a highly specific and sensitive serological test for human herpesvirus 8 (HHV-8) infection that uses the Luciferase Immunoprecipitation System (LIPS). A mixture of four virus-specific antigens, including K8.1, v-cyclin, ORF65 and LANA, was shown to provide more robust detection of HHV-8 infection than traditional methods due its ability to detect very low viral loads.

Simple, Quantitative Sensitive High-throughput Antibody Detection for Lyme Disease

Read more about Simple, Quantitative Sensitive High-throughput Antibody Detection for Lyme Disease

This technology is for compositions and methods for diagnosis of Lyme disease. Currently, Lyme disease is diagnosed by clinical exam and a history of exposure to endemic regions. Although, laboratory tests may aid diagnosis, the best tests currently available are slow and labor intensive and require understanding of the test, and infection stage. A two-step antibody based test process is currently the recommended laboratory test. The first step is either an enzyme immunoassay (EIA), or an indirect immunofluorescence assay (IFA).

Monoclonal Antibody Against Human Alpha-5 Integrin that Does Not Disrupt Adhesive Function

Read more about Monoclonal Antibody Against Human Alpha-5 Integrin that Does Not Disrupt Adhesive Function

This technology includes a rat monoclonal antibody termed mAb11 was generated against the human alpha-5 integrin subunit and can provide immunological characterizations without disrupting integrin adhesive function. It permits characterization of its localization even if the receptor is bound to its fibronectin ligand. The antibody is commercially available from Millipore Sigma.
