Özet

Most of the strategies developed in bone tissue engineering in the past three decades have been aimed to repair/regenerate the tissue with forming elements such as osteoblasts and bone morphogenetic proteins. All these materials are selected as they are known to induce bone formation. Since it is known that bone turnover in basic multicellular units (BMUs) is at equilibrium, inducing an imbalance in this process via molecules known to resorb and transmit resorption signals and therefore initiate activation in bone forming cells from adjacent tissue may offer a radical approach to bone regeneration. Possible targets for such an approach may include resorbing molecules such as tartrate resistant acid phosphatase (TRAP) and cathepsin K. Delivering these enzymes (TRAP and cathepsin K) and/or other molecules involved in bone resorption into bone defects and thus obtaining a concentration difference in the levels of these materials may induce bone forming cells to balance bone turnover, therefore inducing bone regeneration.
