#1: What happens to the cells of ALL (Acute lymphocytic leukemia) patients? What happens to the patients is that the immature cells are attacked by the cancer cells, causing them to be stuck in the growing stage, which causes the immune system (system that protects the body from sickness) to become dangerously weak. #2 What was the challenge Stanford researchers faced when trying to find a cure? The challenge that the Stanford researchers faced was that the cells needed to be tested in a lab environment, and although they did have cancerous precursor B cells, they could not keep them alive long enough to test them. #3 How were the cancerous cells transformed? What did they change into?[ The cells were transformed using a transcription factor- a protein in the body that shows the immature cell what it needs to become. Somehow, the cancer cells began to look like what they would have become if they had not had the disease.
