Question

Soon after nerve growth factor (NGF) was discovered, investigators injected newborn mice with antibodies that inactivated it. Compared to control mice, those that received the antibody showed massive amounts of nerve cell death. After a week of daily antibody injections, up to 99% of the neurons in certain parts of the nervous system of these mice were gone. What do these results suggest

Answer 1

Step-by-step explanation:

The results suggest that nerve growth factor is directly/indirectly involved in stimulating the growth and maintenance of certain parts of neurons in new born mice.
