15. (5 pts) You read a paper where the scientist hypothesize that alurin is a small peptide responsible for induction of epithelial cell sheets during early embryogenesis. In one experiment a culture of isolated epithelial cells are exposed to different concentrations of alurin. After 24 hrs ALL the epithelial cells make intestinal cells. Based on what you know about cell-cell interactions, is alurin establishing a morphogen gradient (Yes or No)? Explain in 1-2 sentences.

Expert Solution
Step 1
A morphogen is a substance whose non-uniform distribution governs the pattern of tissue development in the process of or pattern formation
In the experiment it says that the sample of epithelial cells were subjected to different concentrations of alurin and after 24 hours it was observed that all the cells started making intestinal cells.
