limbs/digits/tail
abnormal interdigital cell death ( J:155754 )
• reduced apoptosis compared to wild-type controls in TUNEL and acridine orange stained E14.5 autopods sections
• decreased staining being most evident in IDT between digits 2 and 3 and between digits 3 and 4 of the hindlimbs
• local application of BMP4 or versican fragment induces apoptosis in the IDT in the mutant
syndactyly ( J:155754 )
• soft-tissue syndactyly (STS) with 100% penetrance
• at least three of four limbs are involved
• the interdigital tissue (IDT) between hindlimb digits 3 and 4 is most frequently involved and has the greatest severity of STS
• persistence of the IDT with a low cell density and loose, amorphous matrix
• reduced versican clearance
interdigital webbing ( J:155754 )
• syndactyly is caused by the persistence of the skin web between the digits
• no osseous syndactyly or patterning defects
