Lactoferrin, a glycoprotein found in milk, has stimulated osteoblast proliferation and differentiation, but has remained relatively unexplored as a biomaterial component. In this study, artificial extracellular matrices consisting of fibrils of collagen type I containing lactoferrin were used as coatings for the biocompatible polymer poly(lactic-co-glycolic acid) (PLGA). The numbers of cells, their viability and proliferation rate were evaluated in various time intervals. Additionally, cell initial spreading area on day 1 was measured. The results show that lactoferrin accelerates fibril-logenesis, leads to increased osteoblast cell numbers 1 and 3 days post-seeding, and encourages their proliferation in each of the tested time intervals.
