What is the role of cells expressing higher levels of Delta in Delta-Notch signaling?
What is the role of cells expressing higher levels of Delta in Delta-Notch signaling?
- To promote neurogenin expression in surrounding cells
- To increase their own expression of Delta
- To prevent neurogenin expression in surrounding cells (correct)
- To differentiate into neurons
What happens to cells not receiving Delta signal in Delta-Notch signaling?
What happens to cells not receiving Delta signal in Delta-Notch signaling?
- They increase their expression of Delta
- They increase their expression of Neuro D (correct)
