Osteogenesis Imperfect (OI) (Brittle Bones Disease) is the most common hereditary connective tissue disease. The main clinical forms of OI are quantitative and qualitative anomalies type I collagen, protein in bones [8]. In modern literature, cases successful delivery patients with imperfect osteogenesis described, however this disease considered a contraindication to pregnancy, when it advised...

objective a 4-month-old female with osteogenesis imperfecta (oi) type ii was admitted in picu of our center due to severe respiratory distress and fever with a diagnosis of severe pneumonia, and mechanical ventilation was initiated. due to severe hypotonia, ncv and emg were performed, and spinal muscular atrophy (sma) type i was diagnosed.

objective(s) it is believed that the mesenchymal stem cell (msc) differentiation and proliferation are the results of activation of wnt signaling pathway. on the other hand, lithium chloride is reported to be able to activate this pathway. the objective of this study was to investigate the effect of lithium on in vitro proliferation and bone differentiation of marrow-derived msc. materials and ...

background: characteristics of differentiated osteoblasts from adipose derived stem cells (adscs) in compared with isolated osteoblasts from normal bone such as calvaria are unknown. the aim of this study was determination and comparison of phenotypic characterization between differentiated osteoblasts from stem cells and calvaria osteoblasts in vitro . methods: in this study, mesenchymal stem ...
