A Robotic Surgery Platform for Automated Tissue Micromanipulation in Zebrafish Embryos

Mahmut Selman Sakar, Ece Özelçi, Andrew Charles Oates, Laurel Ann Rohde, Erfan Etesami

Microsurgical manipulations are key experimental techniques in life science research, particularly in embryology. These techniques are most often performed manually by highly skilled scientists, posing limitations on speed, precision, and reproducibility. ...

Deconstructing body axis morphogenesis in zebrafish embryos using robot-assisted tissue micromanipulation

Matthias Rüegg, Mahmut Selman Sakar, Erik Mailand, Ece Özelçi, Andrew Charles Oates

Classic microsurgical techniques, such as those used in the early 1900s by Mangold and Spemann, have been instrumental in advancing our understanding of embryonic development. However, these techniques are highly specialized, leading to issues of inter-ope ...

Actuated 3D microgels for single cell mechanobiology

Christina Myra Tringides, Mahmut Selman Sakar, Ece Özelçi, Berna Ayse Özkale Edelmann

We present a new cell culture technology for large-scale mechanobiology studies capable of generating and applying optically controlled uniform compression on single cells in 3D. Mesenchymal stem cells (MSCs) are individually encapsulated inside an optical ...
