A medical student assisting with this research is interested in applying the results of the experiment to spinal cord injury in humans. The principal investigator responds that this study does not apply to such injury, most likely because:

the study only examined the behavior of macrophages in response to uninjured nerve cells and astrocytes.

Explanation:

The study was only considerate on microphage migration in response to conditioned media from resting cells
