Phenotype Image Detail
Caption Ultrastructural study of wild-type and Fbn1Tsk/Fbn1+ mice skin. A,C, and E, Normal wild type mouse; B,D and F, Fbn1Tsk/Fbn1+ mouse. A and B are low power views (5,000x) showing basal keratinocytes, the dermo-epidermal junction as represented by the lamina densa (open arrows), and the upper dermis. In both mice, the dermis is dominated by collagen bundles. Microfibrillar bundles and elastic fibers are indicated by closed arrows. B reveals the presence of larger microfibrillar bundles with abundant microfibrils but little elastin. C-F are high magnification views of elastic fibers and microfibrillar bundles. These appear less well defined in mutant skin (D and F) than in wild-type skin (C and E). In particular, the striation pattern of microfibrils (arrowheads) seen with the wild-type mice (C and E) was less apparent in the mutant skin. Bars: A and B, 3,000 nm; C-F, 250 nm.
