The invention provides materials and methods related to a transgenic non-human mammal whose genome comprises a disrupted PAPP-A allele. Methods for making such transgenic non-human mammals, and using them identify and characterize agents that affect conditions related to PAPP-A activity, such as vascular restenosis, atherosclerosis, wound healing, cancer, fibrosis, bone development, fetal development, longevity, and fracture repair, also are provided.
