title: [Bone and adipose tissue formation].
abstract: Leptin has been described to have a crucial role in bone homeostasis by systemic as well as local action. Systemically, leptin seems to inhibit bone formation controlled by a feedback loop including osteocalcin and insulin. Even though the action seems to be bone site specific, as well as gender- and time-dependent, the results showing the interaction of these three factors are in part still inconsistent. In this article the complex effects of leptin, insulin, and osteocalcin on bone and fat metabolism are summarized.
