title: CRSBP-1/LYVE-l-null mice exhibit identifiable morphological and functional alterations of lymphatic capillary vessels.
abstract: CRSBP-1, a membrane glycoprotein, can mediate cell-surface retention of secreted growth factors containing CRS motifs such as PDGF-BB. CRSBP-1 has recently been found to be identical to LYVE-1, a specific marker for lymphatic capillary endothelial cells. The in vivo role of CRSBP-1/LYVE-1 is unknown. CRSBP-1-null mice are overtly normal and fertile but exhibit identifiable morphological and functional alterations of lymphatic capillary vessels in certain tissues, marked by the constitutively increased interstitial-lymphatic flow and lack of typical irregularly-shaped lumens. The CRSBP-1 ligands PDGF-BB and HA enhance interstitial-lymphatic flow in wild-type mice but not in CRSBP-1-null animals.
