Image datasets associated with Gut Analysis Toolbox

The images are sample image datasets associated with the software: Gut Analysis Toolbox (GAT). The dataset contains immunofluorescence images of enteric neurons and glia labeled with different markers. The data is mostly from mouse and human colon or small intestine. Channels corresponding to Hu labelling can be used for segmenting enteric neurons in GAT. Channels corresponding to GFAP (enteric glia) or neurons with markers labelling the cell body and processes (ChAT, Calbindin, Calretinin) can be used as a ganglia marker for segmenting the ganglia The data is two-dimensional (2D) with some images having multiple channels. The data is mostly in tif format, except for one dataset that is czi (Fiji using bioformats or aicspylibczi in Python). Calcium imaging data is 2D+Time.

At frame 52, 100 uM of ATP is added which causes enteric glia, neurons and blood vessels to respond. This causes slow drifting in the field of view. • mouse_GCamp_calcium_movement.tif Wnt1-GCaMP3 mouse where GCamP3 is a genetically encoded calcium sensor expressed by enteric neurons and enteric glia Imaging performed at Monash University. 745 frames in total acquired at 1.162 frames per second with drifting over time Tissue source: Stamp & Hao laboratory, University of Melbourne.

Types of Neurons in the Human Colonic Myenteric Plexus Identified by Multilayer Immunohistochemical Coding. Cellular and molecular gastroenterology and hepatology, 16(4), 573–605. This data is a myenteric wholemount from the descending colon of a Human. It has 14 different markers, 6 different rounds of staining. Every round has pan-neuronal marker Hu as a reference marker.There are 19 images. The filenames follow the convention: H2202Desc_layer num_ganglia num_markername.tif H2202 is the sample name, Desc means descending colon Here layer num corresponds to the round of staining, so Layer3, means its the 3rd round of staining. ganglia num is specified as multiple ganglia can be imaged from same tissue. markername corresponds to the marker used. Markers used are: Hu, 5HT, ChAT, NOS, CGRP, Enk, SP, Somat, VACht, NPY, Calbindin, Calretinin, NF, VIP Abbreviations: Hu: Pan-neuronal marker 5HT: Serotonin (5-Hydroxytryptamine) ChAT: Choline acetyltransferase nNOS: neuronal Nitric Oxide Synthase (NOS in these images are actually nNOS) CGRP: Calcitonin Gene-Related Peptide Enk: Enkephalin SP: Substance P Somat: Somatostatin VACht: Vasoactive Intestinal Peptide (VIP) NPY: Neuropeptide Y NF: neurofilament 200
