BACKGROUND AND OBJECTIVE: Low-Level Laser Therapy (LLLT) has been suggested to improve bone tissue healing. The cellular and molecular mechanisms involved in this effect are still unclear but bone cell proliferation and differentiation alteration have been proposed. The aim of the present study was to investigate, in vitro, the effect of LLLT...

A combination of autologous bone marrow stromal cells (BMSCs) and biomaterials is a strategy largely developed in bone tissue engineering, and subcutaneous implantation in rodents or large animals is often a first step to evaluate the potential of new biomaterials. This study aimed at investigating the influence of the immune status of the...

Bone marrow stromal cells (BMSCs) have been demonstrated to induce bone formation when associated to osteoconductive biomaterials and implanted in vivo. Nevertheless, their role in bone reconstruction is not fully understood and rare studies have been conducted to follow their destiny after implantation in syngenic models. The aim of the...

Interaction of host blood with biomaterials is the first event occurring after implantation in a bone defect. This study aimed at investigating the cellular and molecular consequences arising at the interface between whole blood and biphasic calcium phosphate (BCP) particles. We observed that, due to calcium capture, BCP inhibited blood...

Particulate forms of biphasic calcium phosphate (BCP) biomaterials below 500 μm are promising bone substitutes that provide with interconnected open porosity allowing free circulation of fluids and cells. Dispersion of the particles in the surrounding tissues at the time of implantation is a major drawback preventing from an easy use. We have...
