introduction: the aim of this study was to investigate the presence and distribution of cell surface terminal sugars in developing cartilage of the primordial vertebrae in rat embryo. material and methods: fifty female and 25 male wistar rats were chosenrandomly. after adaptation, mating was done. vaginal plug observationwas performed on o-day of gestation. specimens were collected from 9-18 da...

Notochord is an axial structure derived of embryonic mesoderm and in addition to structural supporting role in inducing nearby germinal layers, it has a basic role in formation of organs such as vertebral column, axial vessels, neural tube and primitive gut. This organ undergoes essential changes during the development process. First, arises from the primitive node and terms notochordal process...

Lectin binding histochemistry was performed on the developing sympathetic ganglionic cells to investigate the distribution and density of defined carbohydrate terminals on the cell surface glycoproteins during autonomic system morphogenesis. Sprague-Dauley rat embryos from 9th gestational day to birth were fixed and paraffinized. Serial sections of these specimens were incubated with different ...

introduction: it is well known that glycoconjugates on the cell surface of embryonic cells as well as extracellular matrix (ecm) are involved in many developmental phenomena including cell differentiation and maturation. these molecular events have not received proper attention during pituitary cell differentiation. the purpose of this study was to investigate glycoconjugate distribution on cel...
