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 or research here considered mostly what macrophages are responsive to in microenvironment. The location where an injury occurs produces a different environment from the resting tissue. The study was only considerate on microphage migration in response to conditioned media from resting cells
