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.
Rabbit Antisera to Various Matrix, Matricellular, and Other Secreted Proteins
The extracellular matrix (ECM) is composed of a group of proteins that regulate many cellular functions, such as cell shape, adhesion, migration, proliferation, and differentiation. Deregulation of ECM protein production or function contributes to many pathological conditions, including asthma, chronic obstructive pulmonary disease, arthrosclerosis, and cancer. Scientists at the NIH have developed antisera against various ECM components such as proteoglycan, sialoprotein, collagen, etc.. These antisera can be used as research tools to study the biology of extracellular matrix molecules.
