N normal phenotype
integument
• defective adhesion and more pronounced spreading
• cells do not grow into a confluent monolayer and undergo rapidly initiated terminal differentiation
• patchy hair loss over the dorsal midline of the skull
• intermixed with normal follicles
• less affected than in Itgb1tm1Ref/Itgb1tm1Ref Tg(KRT1-5-cre)5132Jlj mice
• however, no subepidermal blistering is observed

• defective adhesion and more pronounced spreading
• cells do not grow into a confluent monolayer and undergo rapidly initiated terminal differentiation
