What are the properties of the primary organizer?
Primary organizer has the ability for self-differentiation and organization. It is responsible to induce changes within the cell and to organize surrounding cells, including the induction and early organization of neural tube. It is responsible to determine the main features of axiation and organization of the vertebrate embryo. Induction is a tool-like process that utilizes by this center of activity through which it affects changes in surrounding cells and as such influences organization and differentiation. The surrounding cells that are changed by the process of induction, can act as secondary inductor centers with abilities to organize specific sub-areas. Therefore, the transformation of the late blastula into an organized condition of the late gastrula appears to be dependent on a number of separate inductions, all integrated into one coordinated whole by the formative stimulus of the primary organizer located in the pre-chordal plate area of the endodermal-mesodermal cells and adjacent chorda-mesodermal material of the early gastrula.
