Phenotype Image Detail
Image
Caption A: Histological sections of quadriceps muscle, footpad and ear of 14 week old male wild-type (WT) and Syt7tm1Nan/Syt7tm1Nan (KO) mice. Increased accumulation of connective tissue is evident in the sections of mutant mice. Skeletal muscle sections are stained with toluidine blue, footpad sections with hematoxylin and eosin and skin sections with Masson's trichrome, which stains collagen fibers in blue. Bars, 100um. B: Toluidine blue-stained sections of quadriceps muscle from male wild-type and mutant mice at 4, 8 and 44 weeks old. Infiltration of inflammatory cells is initially detected (black arrows), followed by tissue injury, fiber invasion by phagocytic cells (white arrow), and collagen deposition (black arrowheads). Bars, 25um.
