Caption Cdsn deficiency results in stratum corneum detachment due to defective desmosome formation. (A) Macroscopic appearance of formalin-fixed Cdsntm1Mmat/Cdsntm1Mmat (-/-) newborn mouse with skin erosions on the limbs. (B) Loss of upper epidermis due to detachment of the stratum corneum from the underlying granular layer and/or within the upper granular layers in mutant mouse epidermis. Dilation of capillaries beneath the affected epidermis was also noted (arrows). (Scale bar: 100 um) (C) Electron density of each corneodesmosome from mutant mice (lower left, arrowhead) was markedly lower than that in wild-type (+/+) mice (upper left, arrowheads). In contrast, formation of cornified cell envelopes (arrows) was indistinguishable between wild-type and mutant mice. (Right) Higher magnification of the outlined areas shown in Left. (Scale bars: 100 nm).
