In early vertebrate embryonic development, a number of pathways, such as Wnt, Hedgehog, and Notch, regulate differentiation and organ formation. They operate by __________.
A)formation of new transcription factors at each stage
B)transcription activation due to interaction among transcription factors
C)cell signaling mediated by receptor binding
D)establishing anterior-posterior and dorsal-ventral symmetry
E)stimulating MADS box genes
