Q

WHAT DOES SECRETION OF BMP INTO THE DORSAL NEURAL TUBE DO

A

INDUCES TRANSCRIPTION OF OTHER TRANSCRIPTION FACTORS SUCH AS PAX6 PAX7 PAX3 THAT CAUSE NERUAL TUBE PROGENITORS TO ACQUIRE DORSAL IDENTITIES

Q

WHAT IS THE OVERALL FUNCTION OF SONIC HH

A

TO CONFER A DV PATTERN OF TRANSCRIPTION FACTORS ON PROGENITOR CELLS. THESE TFS ARE THE UPSTREAM MASTER REGULATORS OF PARTICULAR NEURONAL FATES
