Collagen VI is a survival factor for skeletal muscle produced by endomysial cells and localized in connective tissue around muscle fibers. Mutations of its genes (COL6A1, COL6A2 and COL6A3) cause two muscular disorders, Bethlem myopathy and Ullrich disease. Expression of Collagen VI is highly dynamic during development, suggesting that developmental and homeostatic cues of the muscle microenvironment are relevant to confine its expression in this tissue. In face of the large body of work highlighting the relevance for human diseases of the adhesion of muscle cells with their surrounding extracellular matrix, remarkably little is known on how myogenic cells control gene expression in the connective tissue cells that produce such matrix. By expressing promoter-lacZ constructs in transgenic mice, we identify a Col6a1 gene enhancer region that is necessary for activation of transcription in connective tissue cells associated with skeletal muscle. By means of a lacZ transgenic mouse line crossed in metD/D mutant background, in which muscles of limb buds fail to form, we provide evidence that the presence of cells of the myogenic lineage is needed for enhancer activation in mesenchymal cells. Accordingly, lack of myogenic cells in limb buds of metD/D mice reduces Collagen VI deposition in connective tissue. The Col6a1 enhancer characterized here is conserved in mammals and may be relevant in some cases of heritable diseases of Collagen VI.
