the effects of prostaglandin e2 ( pge2 ) on the degradation of collagen and non-collagenous peptides in clonal osteoblastic mc3t3-e1 cells were investigated by using highly sensitive assay methods for pz-peptidase , collagenase-like peptidase ( cl-peptidase ) , dipeptidyl-aminopeptidase ( dap ) , leucine aminopeptidase ( lap ) , and post-proline cleaving enzyme ( ppce ) .
