# Histology and Histomorphometry Core

> **NIH NIH P01** · COLUMBIA UNIVERSITY HEALTH SCIENCES · 2020 · $346,942

## Abstract

The four projects of this Program Project heavily rely on the use of mouse models to demonstrate their
hypotheses. The purpose of the Histology and Histomorphometry Core is therefore to consolidate equipment
and expertise to provide the Investigators of these projects with state-of-the-art, quality controlled histologic
and histomorphometric analyses of bone, pancreas and brain specimen as well as microCT of mouse bones.
The Core contribution to this Program Project will be at 4 levels:
1. Processing mouse specimens for histology, immunolabeling and histomorphometry. Fixed and partially
 dehydrated mouse skeletons or pancreata will be embedded in plastic medium (vertebrae and long bones)
 or paraffin (pancreas). Fixed mouse brain specimen will either be sectioned without embedding or cryo-
 embedded and cryo-sectioned.
2. Performing specific stainings and immunostainings of mouse tissues sections. Classic histology stainings
 such as Hematoxylin/Eosin, Toluidine Blue, von Kossa/Van Gieson, Goldner trichrome, Cresyl violet as
 well as more specific reactive ones such as TUNEL and TRAP stainings will be performed by the Core
 personnel at the request of investigators. The Core will also perform immunodetection studies using
 fluorescent and enzymatic detection on sections.
3. Performing histomorphometric analyses of mouse bone, pancreas and brain specimens. The
 OsteoMeasure Histomorphometry System (OsteoMetrics Inc., Decatur, GA) will be used to assess static
 parameters, such as bone volume, trabecular number and cell counts, and dynamic parameters of bone
 formation, such as mineral apposition rates, from non-decalcified bone sections. It will also be used to
 quantify cell mass/proliferation in pancreas and TUNEL or BrdU positive cells in brain sections. Image J will
 be used for all other quantifications. The Core will provide investigators with histomorphometric data and
 will help them in evaluating their biological relevance.
4. Analyzing mouse bone specimen by microCT. Fixed and partially dehydrated mouse long bones and
 vertebrae will be provided to the Core by project investigators. These specimens will then be scanned
 using a VivaCT 40 microCT (Scanco Medical, Switzerland).
