Presence of germ layers trigger hormonal release from endocrine glands, signaling to certain cells to express genes,
Cell signals through plasmodesmata allow coordination of cellular activities and cell differentiation.
Cues from the cytoplasm and from surrounding cells can induce changes in gene expression.
