ADAMTS9 is the most conserved member of a large family of secreted metalloproteases having diverse functions. Adamts9 null mice die before gastrulation, precluding investigations of its roles later in embryogenesis, in adult mice or disease models. We therefore generated a floxed Adamts9 allele to bypass embryonic lethality. In this mutant, unidirectional(More)
Skeletal muscle development and regeneration requires the fusion of myoblasts into multinucleated myotubes. Because the enzymatic proteolysis of a hyaluronan and versican-rich matrix by ADAMTS versicanases is required for developmental morphogenesis, we hypothesized that the clearance of versican may facilitate the fusion of myoblasts during myogenesis.(More)
Healthcare providers treating wounds have difficulties assessing the prognosis of patients with critical limb ischemia who had been discharged after complete healing of major amputation wounds. The word "major" in "major amputation" gives the impression of "being more severe" than "minor amputation." Therefore, even if wounds are healed after major(More)
YAP (yes-associated protein) and TAZ (transcriptional coactivator with PDZ-binding motif) are part of a classical pathway that controls contact inhibition in the Hippo pathway. YAP and TAZ were recently reported to act as nuclear relays of mechanical signals that communicate extracellular matrix rigidity and cell shape. However, the role of YAP/TAZ(More)
Keloids gradually change their shapes as they grow. We hypothesize that the change of keloid morphology reflects the incremental change of the stress patterns occurring in peri-keloid regions due to movement of the keloid-carrying body part. To examine the validity of this hypothesis, we used three-dimensional finite element analysis to calculate the(More)
Chronic expanding haematoma (CEH) is a rare type of haematoma that enlarges slowly and continuously without coagulation. It can occur following surgery because of shear stress-induced bleeding in the scar tissue between the subcutaneous fat and fascia. We present three cases of large chronic CEH that were successfully treated with triamcinolone injections.(More)
