Secretion and fibrillogenesis of collagen-I are separately controlled molecular pathways in the fibroblast, where surprisingly endocytic recycling is required for fibril formation and is increased in fibrotic fibroblasts.

Reduced lung myofibroblast proliferation is a unifying feature in multiple models of developmental emphysema and inhibition of myofibroblast proliferation is sufficient to cause this pathology.
A multi-disciplined approach uncovered microRNA-199a/b-5p as important regulators of chondrogenesis, which negatively regulate mRNAs such as FZD6, ITGA3, and CAV1 for protective purposes during chondrogenesis.
Styxl2, a sarcomeric muscle-specific pseudophosphatase in vertebrates, functions in sarcomere assembly by promoting protein degradation of non-muscle myosin IIs.
Disruption of the intracellular vimentin network upon cellular stress results in enhanced cell surface vimentin on human osteoarthritic chondrocytes and might represent a novel membrane-associated marker of stress-induced premature senescence.
