Abstract: The current study aimed to describe the histological changes of the femur and tibia of the post-hatching quail. Femur and tibia from 1-day- to 6-weeks post-hatching quail were processed for light microscopy. Histological examination revealed that endochondral ossification was a delayed process in the development of femur and tibia preceded by periosteal ossification. Femur and tibia of 1-day-post-hatching quail consisted of growth cartilage enclosed in a tube of periosteal bone collar. The collar extended toward the epiphysis iding it into articular cartilage proper and lateral articular cartilage. Down to the articular cartilage, there was a physeal growth cartilage, in which the chondrocytes were organized into resting, proliferative and hypertrophic zones. Focal areas of hypertrophic chondrocytes were observed in the epiphysis of the tibia but not of the femur, which acted as a nidus for formation of the secondary ossification centre after in 2-week-posthathcing quail. Primary ossification centre was seen in both femur and tibia after 2 weeks and ossification continued replacing the cartilage until the 6th week when only permanent articular cartilage remained. Cartilage canals were present in both femur and tibia starting from the day 1, but chondrified and completely disappeared after the 6th week. The current study suggests that the periosteal ossification preceded the endochondral ossification and plays an important role in quail long bones development.

Abstract: The current study conducted a careful description of the histological events during the embryonic development of quail stomach. Daily histological specimens from the quail stomach from day 4 to day 17 post incubation were examined by light microscopy. The primitive gut tube of the embryonic quail appeared at day 4 post incubation. The gut tube consisted of an endodermal epithelium of pseudostratified type, surrounded by splanchnic mesenchyme. The prospective glandular epithelium invaginated at day 5 in the proventriculus and gradually developed to prospective proventricular glands. The muscular coat became distinguished at day 7 and day 8 in the proventriculus and gizzard, respectively. Transformation into simple columnar epithelium occurred in both proventriculus and the gizzard at day 12. The gizzard epithelium gave rise to tubular invaginations also at day 12. Canalization of the gizzard tubular glands was recognized at day 14. By day 15, the proventricular surface epithelium invaginated in a concentric manner around a central cavity to form immature secretory units that contained inactive oxyntico-peptic cells. The mucosal folding in the gizzard appeared at day 15 to form plicae and sulci. The wall of the proventriculus and gizzard at day 17 acquired histological features of post-hatching birds.

Abstract: The current study was undertaken to describe the main histological development stages of long bones (tibia and femur) from Japanese quail (Coturnix coturnix japonica) embryos. Whole Limbs or just tibia and femur of fifty Japanese quail embryos of different ages were fixed and embedded in paraffin or Spurr's resin. Paraffin and semi-thin, respectively, were undertaken and examined with light microscopy. Limb bud was established at day 5 of incubation. Mesenchymal cells differentiated into chondrocytes forming a cartilage template in the position of the future tibia and femur at day 6 of incubation. At day 7 of incubation, the cartilage template enlarged and had the shape and position of the future tibia and femur. At day 8, central chondrocytes underwent hypertrophy and were surrounded by a periosteal bone collar. Cellular and vascular invasion from the bone collar into the central zone of the cartilage template, cartilage resorption and formation of marrow tunnel and finally peripheral calcification was seen. Vascular cartilage canals penetrating the epiphysis were observed at day 9 and the canals gradually increased in thickness and number toward the hatching day. Articular epiphyseal growth cartilage with resting, proliferative and hypertrophic zones was clearly established by day 10 of incubation. After 17 days of incubation, the zonation of the articular epiphyseal cartilage were much clear, many cartilage canals were present within the epiphyses. In epiphyses of tibia but not femur, foci of chondrocytes hypertrophy were noticed close to the cartilage canals. The current study timed the main histological sequences of development of tibia and femur of embryonic quail.
