    Abstract

    Functional Tissue-Engineered Bone-Like Graft Made of a Fibrin Scaffold and TG2 Gene-Modified EMSCs for Bone Defect Repair

    A novel biofunctional live tissue-engineered bone-like graft was designed and constructed using a fibrin scaffold loaded with TG2 gene-modified ectomesenchymal stem cells (TG2-EMSCs) derived from nasal respiratory mucosa for bone defect repair.

    Abstract

    Inhibition of ERK 1/2 Kinases Prevents Tendon Matrix Breakdown

    The authors showed that extracellular-signal regulated kinase (ERK) 1/2 were highly phosphorylated in mechanically unloaded tendon fascicles in a vascular niche-dependent manner.

    Abstract

    Stiffening of the Extracellular Matrix Is a Sufficient Condition for Airway Hyperreactivity

    Scientists hypothesized that stiffening of the airway extracellular matrix is a core pathological change sufficient to support excessive bronchoconstriction even in the absence of inflammation.
