Abstract

A system and method for forming a bone construct include providing bone marrow stromal cells on a substrate without disposing the cells within an exogenous scaffold, and culturing the cells in vitro in osteogenic media such that the cells form a confluent monolayer and detach from the substrate to form a self-organized three-dimensional bone construct. A system and method for forming a ligament construct using fibrogenic media and a system and method for forming a functionally integrated bone-ligament construct are also provided.
