Abstract:
Amylin has been reported to have bone-conserving effects. In the present study we evaluated the possible activity of the peptide on human osteoblast-like (hOB) cells in primary culture. Amylin between 10(-9) and 10(-6) M, dose-dependently stimulated cell proliferation with a maximal effect (200%) at 10(-6) M. In addition, amylin increased osteocalcin production when hOB cells were exposed to 1,25(OH)2D3 (10(-8)M) but there was a nonsignificant upward trend on alkaline phosphatase activity. The present results suggest that amylin could be included among the group of peptides endowed with osteogenic activity.
