1 Bone Development Tim Arnett Department of Anatomy and Developmental Biology University College London
2 Bone development Outline Bone composition matrix + mineral Bone formation - intramembranous & endochondral Types of bone - woven & lamellar
3 Bone formation: cell lineages Neural crest flat bones of skull & jaw intramembranous ossification Paraxial mesoderm (somites) axial skeleton - vertebral column endochondral ossification Lateral plate mesoderm appendicular skeleton limbs endochondral ossification
4 Two processes of bone formation (ossification) Intramembranous ossification Flat bones - osteoblasts differentiate from progenitors and form bone directly Endochondral ossification Long bones - formed initially as a cartilage model which is then replaced by bone
5 Regulation of chondrogenic / osteogenic differentiation Osteogenic differentiation of mesenchymal cells induced when Wnt proteins ( a.a. cytokines ) bind to LRP 5/6 & Frizzled co-receptors stabilisation / accumulation of β-catenin increased expression of Runx2 (Cbfa1) - osteogenic transcription factor increased expression of Osx (Osterix) - osteogenic transcription factor + decreased expression of genes required for chondrogenesis
6 Development of flat bones in human head ( intramenbranous ossification )
7 Intramenbranous ossification Bone formation without a cartilage model
8 Intramembranous ossification Bone formation without a cartilage model
9 Intramembranous ossification Newly formed bone may be remodelled quickly by osteoclasts
10 Tooth eruption (cat) ultra-low power section of developing jaw 1 mm
11 Tooth eruption (cat) remodelling of alveolar bone to accommodate developing tooth
12 Tooth eruption (cat) remodelling of woven alveolar bone to accommodate tooth
13 Two types of bone Woven (immature, fracture) large, rounded osteocytes osteocytes irregularly spaced randomly oriented collagen fibres variable collagen fibre diameter rapid matrix mineralisation forms rapidly rapid turnover Lamellar (mature, adult) smaller, flattened osteocytes osteocytes regularly spaced collagen fibres show regular, plywood orientation confers strength regular collagen fibre diameter delayed matrix mineralisation (few days) forms slowly slow turnover
14 Adult lamellar bone cortical, compact trabecular, cancellous
15 Limb bud development human 32 days chick 4.5 days chick 4.5 days
16 Cartilage Simplest tissue - no nerves, no blood vessels - only cells + ECM -primitive
17 Cartilage composition CELLS chondrocytes CARTILAGE FIBROUS COMPONENT collagen type II (+ elastin) (+ collagen type I) EXTRACELLULAR MATRIX GROUND SUBSTANCE glycosaminoglycans proteoglycans ( aggregates)

FORMATION OF BONE. Intramembranous Ossification. Bone-Lec-10-Prof.Dr.Adnan Albideri
FORMATION OF BONE All bones are of mesodermal origin. The process of bone formation is called ossification. We have seen that formation of most bones is preceded by the formation of a cartilaginous model,
Ossification = Osteogenesis
Ossification = Osteogenesis Ossification = Osteogenesis Parts of the fetal skeleton form during the first few weeks after conception By the end of the 8 th week, the skeletal pattern is formed : cartilage
