Bone morphogenetic proteins (BMPs) are a group of growth factors also known as cytokines and as metabologens. Originally discovered by their ability to induce the formation of bone and cartilage, BMPs are now considered to constitute a group of pivotal morphogenetic signals, orchestrating tissue architecture throughout the body. The important functioning of BMP signals in physiology is emphasized by the multitude of roles for dysregulated BMP signalling in pathological processes. Cancerous disease often involves misregulation of the BMP signalling system. Absence of BMP signalling is, for instance, an important factor in the progression of colon cancer, and conversely, overactivation of BMP signalling following reflux-induced esophagitis provokes Barrett's esophagus and is thus instrumental in the development of esophageal adenocarcinoma.
Recombinant human BMPs (rhBMPs) are used in orthopedic applications such as spinal fusions, nonunions, and oral surgery. rhBMP-2 and rhBMP-7 are Food and Drug Administration (FDA)-approved for some uses. rhBMP-2 causes more overgrown bone than any other BMPs and is widely used off-label.
BMPs for clinical use are produced using recombinant DNA technology (recombinant human BMPs; rhBMPs). Recombinant BMP-2 and BMP-7 are currently approved for human use.
rhBMPs are used in oral surgeries. BMP-7 has also recently found use in the treatment of chronic kidney disease (CKD). BMP-7 has been shown in murine animal models to reverse the loss of glomeruli due to sclerosis.
A 2022 study by researchers from the Mayo Clinic, Maastricht University, and Ethris GmBH, a biotech company that focuses on RNA therapeutics, found that chemically modified mRNA encoding BMP-2 promoted dosage-dependent healing of femoral osteotomies in male rats. The mRNA molecules were complexed within nonviral lipid particles, loaded onto sponges, and surgically implanted into the bone defects. They remained localized around the site of application.

La dibotermine alfa est une protéine inductrice de tissu osseux, utilisée en implant dans des fractures du tibia en complément au traitement standard. Elle est réservée à l'usage hospitalier C'est un facteur de croissance humain recombinant qui induit la formation de nouveau tissu osseux. Au niveau moléculaire : elle cible et active un récepteur membranaire à activité enzymatique (récepteur à activité Sérine/Thréonine Kinase.
La signalisation cellulaire est un système complexe de communication qui régit les processus fondamentaux des cellules et coordonne leur activité. La capacité des cellules à percevoir leur micro-environnement et à y répondre correctement est à la base de leur développement et de celui des organismes multicellulaires, de la cicatrisation et du système immunitaire, ainsi que de l'homéostasie tissulaire normale. Des dysfonctionnements dans le traitement de l'information cellulaire peuvent être responsables de maladies telles que le cancer, les maladies auto-immunes et le diabète.
Bone grafting is a surgical procedure that replaces missing bone in order to repair bone fractures that are extremely complex, pose a significant health risk to the patient, or fail to heal properly. Some small or acute fractures can be cured without bone grafting, but the risk is greater for large fractures like compound fractures. Bone generally has the ability to regenerate completely but requires a very small fracture space or some sort of scaffold to do so.
