College of Dentistry Research Core

Overview of Services

College of Dentistry Research Core

Our mission is to facilitate all faculty and student research projects at Texas A&M University College of Dentistry by providing guidance and service through our research core.

The research core at consists of a Histology Core, a Microscopy Core, and an Animal Resource Unit. We have several full-time technicians to staff this facility. Two are dedicated to animal maintenance and compliance. The Histology Core is housed in the main Texas A&M College of Dentistry building and the Micro-Computed Tomography (μCT), Scanning Electron Microscope (SEM), and Confocal microscope are housed in the Sciences Building.

Histology Core Facility

The Histology Core Facility provides oversight and technical support for The Histology Core Laboratory which is a 400 square foot facility equipped with regular laboratory hardware, including:

  • Leitz 1512 microtome
  • VIP Tissue Tek processing station
  • PELCO Biowave Microwave (2)
  • Tissue Tek TEC Paraffin embedding station
  • Slide warmer (3)
  • Histo-orientator
  • Water bath (2)
  • Knife sharpener (2)
  • Dual headed microscope (2)
  • Slide dryers (2)
  • Paraffin oven
  • Vibratomes (2)
  • Tricontinent Multiwash 3 plate washer
  • Equipment for bone histomorphology includes:
    • Buehler Isomet low speed saws (4)
    • Buehler grinding and polishing devices
    • Techcut low speed saws

 

Histology Service Fee

Microscopy Core Facility

The Microscopy Core Facility provides oversight and technical support for the Microscopy-Image Analysis Laboratory. A senior research faculty in the Department of Biomedical Sciences supervises this core. The core contains a Confocal and Microscopy Image Analysis System, a Scanning Electron Microscope, and Micro-Computed Tomography (μCT).

Confocal Microscope

Confocal Microscope System set up for live cell imaging: Leica SP5 (2010 model) confocal system with four lasers and five detectors used with an upright microscope: Laser lines 405, 458, 488, 514, 543, 561, 633.

 

Confocal Microscope Fee

Scanning Electron Microscope (SEM)

The Scanning Electron Microscope area has a JEOL JSM-6010LA SEM and uses a field emission gun with cold cathode. The resolution is 1.5 nm in secondary electron imaging (SE) and 3.0 nm in backscattered electron imaging (BEI) at 30 kV. The airlock specimen chamber allows up to a 32 mm diameter sample. Without airlock, the sample can be up to 150 mm. It has a motorized X-Y stage, automatic SEM condition setup based on sample type, simultaneous multiple live image and movie capture, easy sample navigation at 5x - 300,000x magnifications, quantitative and qualitative elements analysis, low and high vacuum operation and wireless capacity.

Scanning Electron Microscopy Fee

The Micro-Computed Tomography area contains a ScanCo MicroCT 35 Scanner with two terminals. It has a Windows-based microcomputer for image analysis; the associated Windows-based software includes Mimics, Geomagic Studio, Strand 7 Finite Element software, Analyze, and Imaris; and a Windows-based microcomputer set-up to use with Bioquant Osteo.

Micro-Computed Tomography (μCT) Fees

Other Imaging Equipment

The Laser Capture Microdissection Microscope area contains a Leica CTR 6500 UV-laser based microdissection system purchased in 2013, which combines automated upright microscope architecture, three-dimensional optical control of the dissecting laser beam and the dissected area, non-contact tissue sampling, and motorized post-dissection handling.

The Slice Scanning Olympus VS 120-S5 area contains a compound light microscope with an epi-florescence capability that allows standard slides (five 1x3, or two 2x3) to be manually loaded and scanned.  All system components are designed to interact seamlessly, producing a fully automated, high-speed scanning system with excellent flexibility and simple operation. The microscope is equipped with Fluorescence components and can produce fully automated, high-speed, multi-channel fluorescence virtual slide system with flexibility and simple operation.

Nikon epifluorescent microscope equipped for digital monochrome and color image analysis, an X-Y-Z encoded motorized stage, Pentium computer and Elements software, as well as a second Nikon microscope with a Sony DXC-390 camera and Bioquant NOVA software for bone histomorphometry.

 

Zeiss Axioplan microscope with a color digital camera for digital capture.

 

Leica DMRXE microscope with color digital camera for digital capture.
