Highlights
• A novel
Vcan
mouse allele,
Vcan
AA
, has ADAMTS protease-resistant versican.
•
Vcan
AA/AA
mice are viable and develop soft tissue-syndactyly (STS)
•
Vcan
AA/AA
STS is rendered more severe in combination with
Adamts20
Bt/Bt
.
• Mice lacking the versican GAGβ domain, but not the GAGα domain, also have STS.
• The versican GAGβ proteolytic fragment versikine is necessary for web regression.
