Mayo Clinic Center for Cell Signaling in Gastroenterology (C-SiG)

Core Facilities

The Center is composed of three cores.


OPTICAL MICROSCOPY CORE

The Optical Microscopy Core plays an essential role in supporting the overall goals of Center members through three linked objectives:

Objective 1:To provide reliable, accessible, and state-of-the-art microscopic technology to all Center members that facilitates their study of GI cellular signaling cascades.

Objective 2:To educate and train Center members in the use of both basic and sophisticated cellular imaging methods. Emphasis is placed on providing technical instruction as well as educating faculty about how such approaches can expand the scope and breadth of their scientific programs.

Objective 3:To develop and apply state-of-the-art optical imaging technologies to GI tissues/cells.
