Actividad biológica
GRGDSPK (EMD 56574; RGD; 0.1-50 μM; for 4 days) inhibits mineralization in a dose-dependent manner as determined by measuring calcium content and 70 bonehnit area of tissue in parietal bones 18 days old isolated from pregnant Sprague-Dawley rats[1].
GRGDSPK (10, 50 μM; for 4 days) dramatically alteres bone morphology, with a disruption of osteoblast and mineralized matrix organization[1].
GRGDSPK (RGD; 250 μM), added to the medium, effectively blocks integrin-fibronectin binding and significantly increases the average size of wild-type cell aggregates[2].
When GRGDSPK (250 μM) is added, wild-type mesendodermal progenitors exhibits strongly reduced adhesion forces and work, indicating that the detachment parameters recorded are specific for fibronectin and that integrins expressed in mesendodermal progenitors are involved[2].
GRGDSPK (RGD-containing, 1.5 mM, 1.0 mM, and 0.5 mM) and RGD-mod-ified peptides impair the ability of sperm to fertilizebovine oocytes, illustrated by a reduction in cleavage in a dose-dependent manner[3].

Protocolo
Proliferation assays are carried out in 48-well cell culture dishes coated with OCP or HL. In proliferation assays, 7.25×103 cells in 0.5 mL of culture medium are seeded in a 48-well dish. Culture medium is changed every 3 days. After 1, 6, 12, and 18 days of culture, plates are washed thrice with PBS to remove unattached cells, and attached cells are collected by trypsinization. The number of cells is counted using a hemocytometer.
