Abstract
Osteopetroses are disorders of bone remodeling resulting in increased bone mass. Osteopetrosis abnormalities can include changes in osteoclast lineage, bone marrow microenvironment, or both. Little is known about the mechanisms that regulate the activity of different bone cell types. Various agents act on bone in a complicated web of interactions, with either synergistic or diverse effects. Advances in molecular biology have enabled studies in knockout or transgenic animals, providing an insight into the mechanism of bone remodeling.Osteopetroze su poremećaji pregradnje kostiju koji dovode do povećanja koštane mase. Osteopetrotične abnormalnosti mogu obuhvaćati promjene u staničnoj liniji osteoklasta, u mikrookolišu koštane srži ili oboje. Malo se zna o mehanizmima koji reguliraju aktivnost različitih vrsta koštanih stanica. Različiti čimbenici utječu na kost kroz čitav splet međusobnih aktivnosti sa sinergističnim ili raznovrsnim učincima. Napredak u molekularnoj biologiji omogućio je ispitivanja na knockout ili transgenskim životinjama, pružajući uvid u mehanizme koštane pregradnje
