Abstract

The flat bone develops through intramembranous ossification, in which themesenchymal cells are directly driven towards osteogenic lineage without the formation of cartilage template. While long bone develops through endochondral ossification, where cartilage template act as an intermediate stage between mesenchymal and bone tissues. Although the avian sternum is a flat bone, some studies describe formation of a cartilage template during its development. The aim of the current study was to observethe mechanism of ossification in quail sternum during embryonic development. Thirty quail embryos were collected for the current study (5 embryos/ day) during the period between Day (D) 5 and D10 of embryonic development and processed for light microscopy. The differentiation of mesenchymal condensation in to the chondrogenic cells was observed at D5whereas the secretion of extracellular matrix could be evident at D6. The cartilage primordia were observed by D7 which wereconsisted of chondrocytes, embedded in matrix and surrounded by perichondrium. Later these primordia were developed in to cartilage template by D8 where the chondrocytes were present in their lacuna. This template attained the shape of future sternum byD9, which was more distinct at D10. Thesepreliminary observationssuggested thatthe quail sternum grows through endochondral ossification. The future study will further explore the histological changes of quail sternum during post-hatching development.
