| Outline of Final Research Achievements |
By locally removing cells from the chorioallantoic membrane (CAM) of a chick embryo and culturing human-derived cells on the CAM, biomedical experiments can be conducted in an environment more similar to that of humans. In this study, we propose a physical method using electrically induced bubbles to locally remove the epithelial cells on the CAM. To control the forces generated by the collapse of the microbubbles, we developed a new distance sensor that precisely measures the distance from the surface of the CAM in liquid (egg white) to the tip of the injector for bubble generation. In cell removal experiments, a pulse voltage of 500V was applied to generate the bubbles. We confirmed that cells within a circular region with a diameter of approximately 350 micrometers on the CAM can be removed when the distance between the bubble generation device and the membrane is set to 200 micrometers. This study establishes a new technique for the microfabrication of biological membranes.

| Academic Significance and Societal Importance of the Research Achievements |
Chick chorioallantoic membrane (CAM) is used as a model for ophthalmic research. For example, during corneal surface excision, it is necessary to precisely remove the epithelial cells on the surface. I have established a method to remove cells on the CAM without damaging the underlying structures.
