Fibrodysplasia ossificans progressiva (FOP) is a rare and disabling genetic condition characterized by congenital malformations of the great toes and progressive heterotopic ossification (HO) in specific anatomic patterns. {file27251}{file27252}Most cases arise as a result of a spontaneous new mutation.
Myositis ossificans progressiva: …the rare progressive type (myositis ossificans progressiva), group after group of muscles become ossified, until the individual is completely rigid. Breathing and swallowing become difficult, and fatal respiratory infections may occur. Steroid treatment of muscle injury and the use of medications to prevent calcification may slow the progression of…
Fibrodysplasia ossificans progressiva (FOP; MIM 135100) is a rare autosomal dominant disease characterized by progressive heterotopic ossification of soft connective tissues including skeletal muscle, tendons and ligaments. Individuals with FOP appear normal at birth, except for malformed great toes and thumbs. The ossification begins in early childhood and progresses over the course of a lifetime. It leads to a debilitating ankylosis of all major joints of the axial and appendicular skeleton and most patients will be confined to wheelchair by the third decade of life. Most FOP cases are sporadic, but there are reports of affected siblings. FOP is caused by mutations in the ACVR1 gene that codes for activin A receptor, type I. It belongs to the protein kinase superfamily and functions as a receptor for bone morphogenetic proteins (BMPs). BMPs are extracellular signaling proteins that are critical for the early development of heart, central nervous system, cartilage, and bone. All of the ACVR1 ...
MONTREAL, CANADA, June 13, 2016 - Clementia is pleased to announce that the Phase 2 Open-label Extension Trial (PVO-1A-202) has been modified to enroll up to 20 new participants and to investigate new palovarotene dosing regimens in participants with fibrodysplasia ossificans progressiva (FOP). The modification to the Phase 2 Open-label extension trial is designated as Part B.. The Phase 2 Trial (Study PVO-1A-201), which is now complete, was designed as an exploratory dose-ranging study that examined the safety and efficacy of two different dosing regimens of palovarotene in participants for acute flare-up. All 40 individuals who completed the Phase 2 trial have enrolled into the Phase 2 Open-label Extension Trial, which provides access to palovarotene to any participant experiencing an eligible flare-up and continues to evaluate the long-term safety and efficacy of palovarotene.. Much has been learned from these studies. Emerging data suggests that the risk to develop heterotopic ossification ...

Heterotopic ossification is a pathological, non neoplastic process of bone formation at ectopic sites, especially inside mesenchymal soft tissues. The disorder can occur localized or generalized.. Local forms are mostly assigned to the entity of Myositis ossificans circumscripta and involve the skeletal muscles. As a result of trauma, often following total hip replacement, or due to neuropathic disorders, e.g. spinal cord lesions, an intramuscular osteogenesis occurs. The osteogenic stimulation of mesenchymal stem cells seems to be the cause, but the pathobiochemical pathways are not known exactly [1].. The generalized disorder Fibrodysplasia ossificans progressiva (FOP, syn. Myositis ossificans progressiva) is a rare connective tissue desease with autosomal dominant heredity. It is characterized by enchondral ossification of muscle, tendons and ligaments after simple injuries, e.g. intramuscular injection [2-4]. The influence of bone morphogenetic proteins on this disorder seems to be evident ...

Myositis ossificans (MO) may be included in the group of lesions described as pseudosarcomas. Its clinical and histological picture frequently mimics a malignant neoplasm and therefore, ultimate diagnosis and implementation of adequate treatment requires the cooperation of interdisciplinary team of physicians. The paper presents the case of 20-year old female patient suffering from severe pain in the right thigh. The patient was initially diagnosed with the lower limb overload. Rest and administration of non-steroidal anti-inflammatory drugs (NSAID) were recommended. Due to the lack of the efficacy of the recommended conservative treatment and detection of tumorous mass on ultrasound examination, the patient was referred to the cancer centre. The diagnostic procedures were extended and an open biopsy of the lesion was performed which revealed the presence of MO. The patient underwent a surgical procedure during which the pathological mass was entirely removed. Follow up examinations conducted ...

We further explored the physiologic significance of the ability of ACVR1[R206H] to respond to activin A in our mouse model of FOP. Inhibition of activin A with a blocking antibody completely inhibited development of HO. Although our results do not exclude the possibility that other ligands may participate, they indicate that activin A (and perhaps the activin A-containing heterodimers, activin AB and AC) must play a major, indeed obligate, role. Moreover, our data were consistent with the idea that activin A, normally produced by cells of the immune system during inflammation (22, 23), is co-opted and reinterpreted by ACVR1[R206H]-expressing cells with osteogenic potential. Hence, activin A may provide the missing link between inflammation and HO in FOP.. We would like to caution, however, that there is a paucity of data implicating activin A as the driver of HO in FOP patients per se; this is largely due to the inability to safely biopsy patients in between, or during, attacks. We cannot ...
We describe a rare case of laryngeal fasciitis ossificans. A 58-year-old man presented with hoarseness and a nodule was found in the larynx. Excisional biopsy was performed, and follow-up laryngoscopy showed complete resolution of this reactive lesion, and normal laryngeal function. The 0.6 cm diameter nodule was well circumscribed and histologically, the lesion was composed of uniform woven bone trabeculae with rimming of osteoblasts and cellular stroma. At the periphery, uniform spindle cells actively proliferated in edematous stroma. Spindle cells were immunoreactive for vimentin and α-smooth muscle actin, suggesting myofibroblastic differentiation. Fasciitis ossificans is histologically identical to myositis ossificans, but tends to present no zonation phenomenon. Fasciitis ossificans is a rare form of heterotopic bone formation, commonly presenting with signs of local inflammation or pain. This patients successful outcome suggests that conservative resection may be both diagnostic and curative.
Fibrodysplasia ossificans progressiva (FOP) is a rare and intractable disease characterized by extraskeletal bone formation through endochondral ossification. Patients with FOP harbor point mutations in ACVR1, a type I receptor for BMPs. Although mutated ACVR1 (FOP-ACVR1) has been shown to render hyperactivity in BMP signaling, we and others have uncovered a mechanism by which FOP-ACVR1 mistransduces BMP signaling in response to Activin-A, a molecule that normally transduces TGF-β signaling. Although Activin-A evokes enhanced chondrogenesis in vitro and heterotopic ossification (HO) in vivo, the underlying mechanisms have yet to be revealed. To this end, we developed a high-throughput screening (HTS) system using FOP patient-derived induced pluripotent stem cells (FOP-iPSCs) to identify pivotal pathways in enhanced chondrogenesis that are initiated by Activin-A. In a screen of 6,809 small-molecule compounds, we identified mTOR signaling as a critical pathway for the aberrant chondrogenesis of ...
Results All patients presented small asymptomatic lesions similar to hamartomas at the level of the dorsal medulla and ventral pons, associated with minor brainstem dysmorphisms and abnormal origin of the vestibulocochlear and facial nerves. The size of the brainstem lesions did not correlate with patients age (p=0.061), age at first flare-up (p=0.733), severity of disability (p=0.194), history of head trauma (p=0.415) or hearing loss (p=0.237). The radiologic features and the absence of neurological symptoms were consistent with a benign process. Variable signal abnormalities and/or calcifications of the dentate nuclei were noted in all patients, while basal ganglia abnormalities were present in nine subjects. Brain calcifications positively correlated with patients age (p,0.001) and severity of disability (p=0.002). ...
Fibrous dysplasia is the uncommon bone disorder in which, instead of the normal bone, fibrous (scar-like) tissue develops, thus weakening the bone affected and causing it to be fractured or deformed. Only a single bone is usually affected by fibrous dysplasia, and it is most commonly a long bone in the legs or arms or the skull. This is the forum for discussing anything related to this health condition

The term heterotopic ossification (HO) describes bone formation at an abnormal anatomical site, usually in soft tissue. HO can be classified into the following 3 types: Myositis ossificans progressiva (fibrodysplasia ossificans progressiva) - This disorder is among the rarest genetic conditions, with an incidence of 1 case per 2 million persons.
After it was shown that bisphosphonates inhibited experimentally induced calcification and bone resorption, their potential application to clinical disorders was obvious, but it took many years for them to become well established.. The earliest clinical applications of bisphosphonates included use of etidronate as an inhibitor of calcification in fibrodysplasia ossificans progressiva (formerly known as myositis ossificans) and in patients who had undergone total hip replacement surgery to prevent subsequent heterotopic ossification and improve mobility.83. One of the other early clinical uses of bisphosphonates was as agents for bone imaging, "bone scanning," for which they still remain outstandingly useful for detecting bone metastases and other bone lesions. The application of pyrophosphate and simple bisphosphonates as bone-scanning agents depends on their strong affinity for bone mineral, particularly at sites of increased bone turnover, and their ability to be linked to a γ-emitting ...

Heterotopic ossification (HO) is a disabling condition associated with neurologic injury, inflammation, and overactive bone morphogenetic protein (BMP) signaling. The inductive factors involved in lesion formation are unknown. We found that the expression of the neuro-inflammatory factor Substance P (SP) is dramatically increased in early lesional tissue in patients who have either fibrodysplasia ossificans progressiva (FOP) or acquired HO, and in three independent mouse models of HO. In Nse-BMP4, a mouse model of HO, robust HO forms in response to tissue injury; however, null mutations of the preprotachykinin (PPT) gene encoding SP prevent HO. Importantly, ablation of SP+ sensory neurons, treatment with an antagonist of SP receptor NK1r, deletion of NK1r gene, or genetic down-regulation of NK1r-expressing mast cells also profoundly inhibit injury-induced HO. These observations establish a potent neuro-inflammatory induction and amplification circuit for BMP-dependent HO lesion formation, and ...

PHILADELPHIA - An international team of scientists, led by researchers at the University of Pennsylvania School of Medicine, is taking the first step in developing a treatment for a rare genetic disorder called fibrodysplasia ossificans progressiva (FOP), in which the bodys skeletal muscles and soft connective tissue turns to bone, immobilizing patients over a lifetime with a second skeleton.. Reporting in the November issue of the Journal of Clinical Investigation senior authors Eileen Shore, PhD, Professor of Genetics and Orthopedics, and Mary Mullins, PhD, Professor of Cell and Developmental Biology, with scientists in Japan and Germany, demonstrated that the mutation that causes FOP mistakenly activates a cascade of biochemical events in soft tissues that kicks off the process of bone development. The linchpin of the cellular signaling gone awry is a receptor for a bone morphogenetic protein, or BMP.. The present study provides the first clear glimpse of how FOP might develop at a cellular ...
By January 1999, she was given a diagnosis of fibrodysplasia ossificans progressiva (FOP), a rare genetic disease that causes muscle tissue and connective tissue to turn into bone - gradually forming a second skeleton and making it nearly impossible to move.
https://my.vanderbilt.edu/chemicalphenomics/ As a way of introduction, I do chemical genetics of zebrafish early development. https://medschool.vanderbilt.edu/chaz-hong-lab/. Briefly, in a manner analogous to classic mutagenesis screens, we conduct high-throughput chemical screens using zebrafish to discover small molecules that specifically perturb embryonic pattern formation. Using the interdisciplinary chemical genetic approach, we have discovered exquisitely selective modulators of the Bone Morphogenetic Protein (BMP), Wnt and Hedgehog pathways, as well as important new signaling components that direct early vertebrate development. For example, I discovered dorsomorphin, the first small molecule inhibitor of BMP signaling. The technology from this effort is nearing an Investigational New Drug (IND) stage for several devastating human diseases, such as fibrodysplasia ossificans progressiva, and incurable pediatric cancers.. Importantly, from this effort, we also have discovered many compounds ...
Maintenance of endothelial lineage is critical for vascularization and vascular homeostasis. Arranged in a single layer that serve as an interface between the vascular wall and bloodstream, the ECs are constantly influenced by hemodynamic forces and inflammatory stimuli. The environment requires that the endothelium is maintained in an appropriate differentiation stage that is able to support both a normal endothelial life span and the necessary turnover, allowing the ECs to participate in angiogenesis and vascular repair. Without proper differentiation, the ECs may become a driver of pathogenesis leading to vascular disease. Previous studies have shown that ECs with mesenchymal and stem cell-like characteristics contribute to cerebral cavernous malformation, atherosclerosis, and the human genetic disorder fibrodysplasia ossificans progressiva (14, 18, 34). Moreover, ECs undergoing mesenchymal differentiation have been traced in studies of vascular calcification, where ECs gain multipotency and ...

Cell culture. iPSCs were maintained in primate embryonic stem (ES) cell medium (ReproCELL) supplemented with 4 ng/ml recombinant human FGF2 (Wako Pure Chemical). To activate the production of induced neural crest cells (iNCCs), mTeSR1 medium (STEMCELL Technologies) was used for the feeder-free culturing of iPSCs. The induction and maintenance of iNCCs and iMSCs derived from iPSCs were previously described (43, 45) (Supplemental Figure 1A). Briefly, iNCCs were induced in chemically defined medium (CDM) supplemented with 10 μM SB-431542 and 1 μM CHIR99021 for 7 days. iNCCs were maintained in CDM supplemented with 10 μM SB-431542, 20 ng/ml FGF2, and 20 ng/ml recombinant human EGF (R&D Systems), and we used up to 20 passages in this study. iMSCs were induced and maintained in αMEM (Invitrogen, Thermo Fisher Scientific) supplemented with 10% (v/v) FBS (Nichirei), 5 ng/ml FGF2, and 0.5% penicillin and streptomycin (Invitrogen, Thermo Fisher Scientific). The FOP-iPSCs used in this study (previously ...
So what to do with my new bone? It may be the sole cause of my right hip pain and my inability to run on pavement since October. What I understand about massage is that, once you develop a bone, you really cant massage it out. Makes sense; you cant massage away your femur either. Then I read about shock-wave therapy. I found two studies saying it was effective for myositis ossificans (yes, thats the fancy name), but when you read the fine print, they never actually got rid of the bone, just the pain. The thing is, I have no pain there, just pain as a result of the stupid os (French for bone; of course they just pronounce that "o")-- in other places. For example, I have now developed a "sympathy knot" on the other side of the gastroc at the same height, which does hurt. Rats ...
Cortically based calcification extends toward adjacent myositis ossificans, without medullary contiguity. There is no cortical destruction.
