Epiboli refers to a rapid and extensive multiplication of cells, typically observed during embryonic development. This process is characterized by a significant increase in cell numbers over a short period, leading to the formation of new tissues and organs. Epiboli is crucial for the overall growth and differentiation of an organism, ensuring that sufficient cellular material is available for the complex structures that will eventually form.

In vertebrates, epiboli is a key event during gastrulation, the process by which the three primary germ layers (ectoderm, mesoderm, and endoderm) are established. During epiboli, cells migrate and rearrange themselves to enclose the yolk, which serves as a nutrient source for the developing embryo. This coordinated cellular movement is essential for establishing the basic body plan.

The mechanisms underlying epiboli involve intricate signaling pathways and cellular behaviors. These include cell division, cell migration, cell adhesion, and changes in cell shape. Disruptions in epibolic processes can lead to developmental abnormalities and malformations, highlighting its critical role in healthy embryonic development. Research into epiboli continues to shed light on fundamental principles of developmental biology and may offer insights into understanding and treating congenital disorders.
