Decreased peritoneal NK cell movement in women with endometriosis by time-lapse imaging estimation
This study used time-lapse imaging to observe peritoneal NK cell movement, revealing decreased motility in women with endometriosis compared to controls.

The study investigated peritoneal immune cell dynamics in women undergoing laparoscopy by performing time-lapse microscopy of single-cell movement from peritoneal fluid, comparing endometriosis versus non-endometriosis groups. NK cells, macrophages, and lymphocytes were tracked in microculture dishes with movement speed and NK pseudopod activity quantified from migration trajectories; the authors report that NK cell mean movement velocity was reduced to about 50% in the endometriosis group, while macrophages and lymphocytes showed no significant speed differences. NK cells also exhibited a significantly lower number of pseudopod movements in endometriosis. This paper is centrally about endometriosis — it directly measures decreased peritoneal NK cell movement and pseudopod activity in time-lapse imaging, supporting impaired immune monitoring relevant to endometriosis.
