HALO® Module

Microglial Activation FL

The Microglial Activation FL module measures fluorescently-stained microglia cell activation in whole slide images. This module detects microglia, soma, and processes, and ultimately reports the number of activated microglial cells, the number of inactivated microglial cells, and the number of negative (non-microglia) cells detected. In addition to cell classification and counting, this tool precisely measures cell processes. It reports the total process area and length, as well as the average process area, length, and thickness, and quantifies process branching by counting the number of branch points and end points per cell. An interactive markup image output option enhances visualization of results by selecting which of the following are displayed: activated microglia, inactivated microglia, microglial processes and skeleton, branch points, end points, as well as the microglia radius.
