The Histopathology & Bio-imaging Lab provides techniques, equipment and protocols for bio-imaging and non-destructive 3-D imaging evaluation as well as histopathological examination and histomorphometric analysis for musculoskeletal research and for developing innovative drugs in bone and joint diseases. So far, the lab has established the following techniques.

Ø  Biophotonic-based Fluorescence Imaging Techniques

Lumina XR Series III could sensitively image bioluminescent / fluorescent reporters and differentially evaluate their distribution in various organs within the same animal. It is employed to examine drug delivery by in vivo bio-imaging analysis.

Ø  X-ray-based Three-dimensional Imaging Techniques

Scanco VivaCT 40 could provide non-destructive imaging and analysis of musculoskeletal tissue. It is employed to perform in vivo and ex vivo measurement of bone and cartilage specimens for micro-architecture.

Ø  Histopathological Examination & Histomorphometric Analysis & Gene Expression Analysis in
    specific cells

Non-decalcified histological processing for bone tissue and static / dynamic bone histomorphometric analysis could be performed in the lab. Techniques of wide special stains for bone and cartilage, such as the VonKossa, tartrate-resistant acid phosphatase (TRAP), alkaline phosphatase, Gömöritrichrome, safranin O and toluidine blue stains are provided in the lab. Further, laser-captured micro-dissection in combination with Q-PCR analysis for gene expression in specific cells is also established in the lab.

Ø  Planar Radiographic Imaging Techniques

The Faxitron MX-20 radiography system can be used for a broad range of bone studies including: bone metastasis, osteoporosis, phenotyping, and bone growth / regeneration studies.

Ø  Description: The Leica Cryostat facilitates preparing frozen sections from decalcified bone tissue for observation under

    a microscope.

Ø  Equipment Name: Leica Rotary Microtome

Ø  Location: Rm. 607, SCM

Ø  Technician: Mr. Michael Wong (whwong@hkbu.edu.hk)

Ø  Description: Leica Rotary Microtome were used for routine sectioning of paraffin-embedded tissues for observation

    under a microscope.

Ø  Equipment Name: The Lumina XR Series III

Ø  Location: Rm. 602, SCM

Ø  Technician: Ms. Nickie Chan (nickie@hkbu.edu.hk)

Ø  Description: The Lumina XR Series III pre-clinical in vivo imaging system offers precise optical and X-ray overlay to

    bring the optical signal into anatomical context. Perkin Elmer Life Science’s Living Image® software automates all

    the controls, settings and analysis.

Ø  Equipment Name: SCANO® vivaCT 40

Ø  Location: Rm. 601, SCM

Ø  Technician: Mr. Michael Wong (whwong@hkbu.edu.hk)

Ø  Description: VivaCT 40 is a fast and flexible in vivo microCT for preclinical studies. The low X-ray dose allows serial

    measurements of individuals. Whole-body scans or scans from selected regions of mice can be made, while head

    and hind limbs of larger rodents can be scanned using beds supplied with the system.

Ø  Equipment Name: BIOQUANTOSTEO Analysis System

Ø  Location: Rm. 601, SCM

Ø  Technician: Dr. Baosheng Guo (borisguo@hkbu.edu.hk)

Ø  Description: The BIOQUANT OSTEO software enables cutting-edge bone biology research in animal models and

    human biopsy. It supports both high-throughput automation and precise manual interaction for ASBMR standard bone

    histomorphometry in digital histology and microCT. Unique tools simplify skeletal phenotyping, characterize arthritis

    models, help quantify cancer metastasis, measure chondrocyte proliferation aid in forensic anthropology and  

    quantify implant osseointegration.

Ø  Equipment Name: Laser Captured Microdissection

Ø  Location: Rm. 609, SCM

Ø  Technician: Mr. Michael Wong (whwong@hkbu.edu.hk)

Ø  Description: Laser Capture Microdissection system (LCM, PixCell IIe from Aucturus) provides one of the best tools

    available to date for isolation of individual cells or specific populations of cells, or bacteria of interest from tissue

    sections for further molecular and biochemical analysis.
