background: in this feasibility study, a mechanically loaded in-vitro tissue culture model of joint morphogenesis using the isolated lower extremity of the 8 day old chick embryo was developed to assess the effects of mechanical loading on joint morphogenesis. methods: the developed in-vitro system allows controlled flexion and extension of the chick embryonic knee with a range of motion of 20 ...

in this study the role of cell death in cartilage canal morphogenesis with morphometrical and histological methods was evaluated. the proximal tibial epiphysis of the chick embryos after fixation and decalcification at the 13 th and 18th days of incubation, with thick and semithin sections and h&e; ,tricromason and feulgen staining were studied. the rsulths were showed that cartilage canals wer...

Carotenoids are secondary metabolites synthesized in plastids that function photosynthesis, photoprotection, growth and development of plants. contribute to the yellowish, orange pinkish-red hues leaves, flowers fruits, as well various aromas. They provide substrates for biosynthesis phytohormones cleavable into smaller apocarotenoids retrograde signals and/or mediate intracellular communicatio...
