mortality/aging
• 19 of 22 mice die between 6-10 days of age
|
growth/size/body
• mice have growth restriction starting a few days after birth
• the few survivors that make it to weaning recover in weight and in general health
|
pigmentation
• increased numbers of phagocytes containing melanosome complexes are found in the dermis
|
• 3-4 day old mice have skin with areas of reduced or absent pigmentation
|
immune system
• 4 day old mouse skin have numerous inflammatory foci with infiltration of granulocytes into the epidermis
• this infiltration is declining by 8 days of age
|
integument
• apoptotic keratinocytes are found in the suprabasal layer of 8 day old epidermis
• at 6 weeks of age, increased apoptosis is extended to both basal and suprabasal keratinocyte layers but is detected only in small affected patches showing abnormal structure and increased proliferation
|
• 4 day old mouse skin have numerous inflammatory foci with infiltration of granulocytes into the epidermis
• this infiltration is declining by 8 days of age
|
• hair growth is retarded on the scaly patches of skin present on neonates
• the few survivors continue to display patches lacking hair growth
|
• abnormal gaps form between the keratinocytes of the suprabasal and basal layers
• keratinocytes are in loose contact with each other forming filopodia that extend into the dilated intercellular spaces
|
parakeratosis
(
J:63055
)
• keratinocytes in the cornified layer of 8 day old mice contains cell bodies and nuclei
|
• the suprabasal layer of 8 day old mice is thicker than controls
|
• keratinocytes in the epidermis have abnormal tonofilament structure and no desmosomes
|
• the epidermis of 8 day old mice is thicker than controls
|
scaly skin
(
J:63055
)
• skin lacking pigmentation becomes hard, inflexible and scaly by 7 days after birth
|
• increased numbers of phagocytes containing melanosome complexes are found in the dermis
|
• 3-4 day old mice have skin with areas of reduced or absent pigmentation
|
cellular
• apoptotic keratinocytes are found in the suprabasal layer of 8 day old epidermis
• at 6 weeks of age, increased apoptosis is extended to both basal and suprabasal keratinocyte layers but is detected only in small affected patches showing abnormal structure and increased proliferation
