Summary Introduction
To differentiate: The transcriptional regulatory mechanism of cytoplasmic determinants and cell signaling involved in induction.
Introduction: In early embryogenesis, the presence of one cell affects the development of other cell. This is known as induction. The process of induction is however influenced by several factors such as cytoplasmic determinants and cell signals whose presence or absence is related to the differentiation of particular cell type.
