FGFR3 mutation causes abnormal membranous ossification in achondroplasia.
FGFR3 gain-of-function mutations lead to both chondrodysplasias and craniosynostoses. Achondroplasia (ACH), the most frequent dwarfism, is due to an FGFR3-activating mutation which results in impaired endochondral ossification. The effects of the mutation on membranous ossification are unknown. Fgfr3(Y367C/+) mice mimicking ACH and craniofacial analysis of patients with ACH and FGFR3-related cr...
متن کاملMatrix vesicles and calcification.
Matrix vesicles (MVs) are extracellular, 100 nM in diameter, membrane-invested particles selectively located at sites of initial calcification in cartilage, bone, and predentin. The first crystals of apatitic bone mineral are formed within MVs close to the inner surfaces of their investing membranes. Matrix vesicle biogenesis occurs by polarized budding and pinching-off of vesicles from specifi...
متن کاملCollagenous bone matrix-induced endochondral ossification hemopoiesis
Transplantation of collagenous matrix from the rat diaphyseal bone to subcutaneous sites resulted in new bone formation by an endochondral sequence. Functional bone marrow develops within the newly formed ossicle. On day 1, the implanted matrix was a discrete conglomerate with fibrin clot and polymorphonuclear leukocytes. By day 3, the leukocytes disappeared, and this event was followed by migr...
متن کاملCalcifying Matrix Vesicles and Atherosclerosis
Artery calcification is a well-recognized predictor of late atherosclerotic complications. In the intima media, calcification starts with apoptosis of vascular smooth muscle cells (VSMCs) and the release of calcifying matrix vesicles with diameter of 0.5-15 μm that can be observed microscopically. In complicated plaques, calcification is generally less frequent. Calcifying vesicles are released...
متن کاملThe localization of chitin synthase in membranous vesicles (chitosomes) in Neurospora crassa.
Polyclonal anti-chitin synthase antibodies raised against the Saccharomyces cerevisiae CHS2 gene product were used to identify and localize chitin synthase in the filamentous ascomycete Neurospora crassa. A single band of approximately 110 kDa was observed in Western blots of total protein extracts of N. crassa, probed with these antibodies. However, several additional bands were labelled when ...
