Bone formation (osteogenesis) is a complex process in which cellular differentiation and the generation of mineralized organic matrix are synchronized to produce hybrid hierarchical architecture. To study mechanisms osteogenesis health disease, there great need for functional model systems that capture parallel, both processes. Stem cell-based organoids promising as functional, self-organizing ...

Although was published many cases of ectopic osteogenesis of traumatic, neurogenic cause or hereditable form, the etiology of ectopic osteogenesis remaining unknown. We present ectopic osteogenesis in the rectus abdominal sheath. The study material was represented from fragments of ectopic bones discovered in rectus sheath of four patients suffering iterative surgical abdominal interventions. T...

Elucidating the molecular mechanisms responsible for osteogenesis of human adipose-derived mesenchymal stem cells (hADSCs) will provide deeper insights into the regulatory mechanisms of this process and help develop more efficient methods for cell-based therapies. In this study, we analysed the role of miR-26a in the regulation of hADSC osteogenesis. The endogenous expression of miR-26a increas...

Researchers believe that most cases of cleft lip and palate are caused by genetic environmental factors. Nevertheless, the exact cause was not found. Nevertheless there allegations condition has something to do with osteogenesis imperfecta heterozygous mutation COL1A2 formation triple helix DNA accompanied Tetralogy Fallot in children a maternal history catatonic schizophrenia followed use valp...

Patients with complete or partial edentulism who have insufficient bone for endosseous dental implant treatment present a challenge for the dental practitioner. Alveolar distraction osteogenesis is a technique for creating bone and soft tissue, without the need for bone grafting and its potential complications. In this article, alveolar distraction osteogenesis is compared with traditional bone...

BACKGROUND Upper limb deformity in children with osteogenesis imperfecta may substantially impair function. The aims of this retrospective work were to study the prevalence of radial head malalignment (dislocation or subluxation) in different types of osteogenesis imperfecta and to identify factors linked to it. METHODS We assessed 489 upper limbs from 254 patients (with a mean age of 9.6 yea...

Osteogenesis imperfecta is a disorder of connective tissue, existing in a severe form (congenita) and a milder form (tarda) both being inherited as an autosomal dominant (McKusick, 1966). Recently Aeschlimann, Grunt, and Crigler (1966) and Bilginturan and Ozsoylu (1966) reported three infants with osteogenesis imperfecta congenita who improved, as regards survival and frequency of spontaneous f...

conclusions although most authors believe that general anesthesia following fiberoptic intubation is the preferred method for oi patients, it is likely that spinal anesthesia is acceptable in such patients. although it is technically difficult, the procedure can be performed by expert anesthesiologists. introduction the choice of anesthetic technique in patients with osteogenesis imperfecta (oi...

Osteogenesis is a complex process that involves the synergistic contribution of multiple cell types and numerous growth factors (GFs). To develop effective bone tissue engineering strategies employing GFs, it is essential to delineate the complex and interconnected role of GFs in osteogenesis. The studies investigating the temporal involvement of GFs in osteogenesis are limited to in vitro stud...
