Description : Bone Morphogenetic Protein 2 is one of the BMPs, some of which belong to the TGF-beta superfamily (BMP2-7). There are more than thirteen BMPs have been discovered nowadays and they are involved in inducing cartilage and bone formation. BMP-2 is expressed in a variety of tissues including lung, spleen, brain, liver, prostate ovary and small intestine. It is a potent osteoinductive cytokine and plays its role in association with osteoconductive carriers such as collagen and synthetic hydroxyapatite. As it shown to stimulate the production of bone, the recombinant human BMP-2 is available for orthopaedic usage and dentistry. The functional form of BMP-2 is a disulflde-linked homodimer and about 26 kDa The precursor of BMP-2 is 259 a.a., containing the 23 a.a. N-terminal signal sequence which will be cleaved by a furin-type protease to form the mature peptide.

The aim of the present study was to develop and examine a new non-invasive injectable graft for the repair of alveolar bone clefts using recombinant human bone morphogenetic protein-2 (rhBMP-2) encapsulated within injectable liposomal in situ gel (LIG).

Different liposomal formulations loaded with rhBMP-2 were prepared, and the effects of the preparation methods and lipid content on the efficiency of rhBMP-2 encapsulation within the liposomes were studied.

The results indicated that the prepared rhBMP-2-LIG prolonged the release and residence time of BMP-2 within rabbits for more than 7 days.

In this study, EPO and BMP2 are adsorbed separately on two 3D-printed PCL scaffold modules that are assembled for codelivery on a single scaffold structure. This assembled modular PCL scaffold with dual BMP2 and EPO delivery was shown to increase bone growth in an ectopic location when compared with BMP2 delivery along a replicate scaffold structure.

Dual delivery produced more dense cellular marrow, while BMP2 had more fatty marrow. Dual EPO and BMP2 delivery is a potential method to regenerate bone faster for prefabricated flaps.

The primary purpose of this study is to use phospholipids-based phase separation in-situ gel (PPSG) in combination with bone morphogenetic protein-2 nanoemulsion (BMP-2-NE) to aid repairing alveolar bone defects.

Injectable PPSG with the best NE formulation was tested for viscosity characteristics, gel strength, water absorption, and in-vitro BMP-2 release.

PPSG that has been loaded with BMP-2 NE may therefore be a promising, fruitful, and less painful paradigm for the noninvasive therapy of CLP with significant effect and extended release.

Recombinant Human Bone Morphogenetic Protein-2 (rhBMP2), a versatile bioengineered protein, is a finely recreated version of the naturally occurring protein in human bodies that significantly contributes to the bone and cartilage formation. In this article, we delve into the various applications of rhBMP2, exhibiting its intricate functionalities in clinical and therapeutic settings.

One of the most prominent areas of application of rhBMP2 lies within orthopedic surgery and dental procedures. The protein is noted for its remarkable capability to stimulate bone growth, efficiently filling up gaps in bones resulting from injury or disease. This has resulted in its extensive usage for spinal fusion surgeries, where it has shown remarkable results in supporting the bone growth needed for the effective fusion of vertebrae. The rhBMP2 protein has also gained popularity in oral and maxillofacial surgery. Its ability to enhance bone growth has been leveraged to support dental implants and treat periodontal diseases.

Another important application of rhBMP2 is in the treatment of complex fractures. Often, certain non-union fractures fail to heal with standard treatments and result in long term pain and disability. In such cases, rhBMP2 is utilized to stimulate bone growth and accelerate the healing process. The protein is adeptly engineered into a sponge that is placed at the fracture site during surgery. This then releases the protein over time, thus stimulating bone formation and healing.

Recombinant BMP2 has also shown promising results in the field of tissue engineering for the generation of new bone tissues. Research in this domain is primarily focusing on combining rhBMP2 with various biomaterials to act as bone graft substitutes, which can be used in bone regeneration therapies. These grafts that incorporate rhBMP2 have shown superior efficacy in promoting bone formation as compared to those without rhBMP2.

Apart from these, rhBMP2 has also shown potential in aiding the healing process for patients battling bone cancer. As bone cancer often needs a high amount of bone grafting after surgery, the application of rhBMP2 promotes faster bone regeneration, thereby accelerating the recovery process for afflicted patients. Furthermore, it reduces the often excessive dependency on autografts, thereby potentially minimizing the risk of donor site morbidity.

While it presents several impressive applications, the usage of rhBMP2 in clinical settings must be regulated with careful consideration. Overdosing or inappropriate administration of the protein can lead to severe side effects, such as ectopic bone formation or even potential immunological responses. Therefore, the dosage and handling of rhBMP2 in any therapeutic application must be accurately monitored.

Recombinant BMP2 has therefore opened up new avenues of treatment in various fields such as orthopedics, dentistry, tissue engineering, and oncology. Its ability to enhance bone formation and healing clearly marks it as a significant medical advancement. With ongoing research and improvements, its wide range of applications could further expand, leading to novel therapeutic approaches in bone-related diseases and surgeries.
