Neutrophils: Two-Photon Data: Neutrophils responding to an infection in the ear

Description

LysM-GFP mice were infected with S. aureus on their ear, and intravitally imaged using two-photon microscopy proximal to the infection. These cells display a fairly directed kind of motion, as they move towards infection foci. For method details, see the references below.

Usage

data("Neutrophils")

Format

## `Neutrophils` An S3 object of class "tracks"; a list with 411 elements. Each element name identifies a cell track. Each element is a matrix containing the following three columns.

t

the time (in seconds)

x

The X coordinate (in micrometers)

y

The Y coordinate (in micrometers)
