hm1

• Allelic Composition: Plec^tm7.1Gwi/Plec^tm7.1Gwi
• Genetic Background: involves: 129P2/OlaHsd * C57BL/6

• ♀: phenotype observed in females
• ♂: phenotype observed in males
• N: normal phenotype

Skin abnormalities in heterozygous and homozygous Plec^tm7.1Gwi mice

integument

abnormal keratinocyte morphology ( J:179812 )

• the numbers of hemidesmosomes appear to be reduced in basal keratinocytes

dermal-epidermal separation ( J:179812 )

• in lesion areas a separation of the epidermis from the dermis at the level of basal keratinocytes is seen

• separation occurs just above the hemidesmosomes of the basal cells, leaving the resulting blister floor covered by cytoplasmic debris including fragments of hemidesmosomes

skin lesions ( J:179812 )

• small epidermal lesions are detectable microscopically most frequently on the head, legs and back skin

abnormal skin exfoliation ( J:179812 )

• following epidermal exfoliation transepidermal water loss is enhanced compared to wild-type controls
