In the initial stages of mammalian life, embryos consist of disorganized clusters of cells. This chaotic beginning is a critical phase in embryonic development.
As development continues, these cells undergo a transformation, organizing themselves into defined shapes and structures. This organization is essential for the proper formation of the embryo.
The study of how embryonic cells 'read' their boundaries to achieve this organization is an important area of research in biology, shedding light on the intricacies of early development.
