Histology, tissue morphology and microscopy

Highly-skilled tissue processing, imaging, and analysis

Study design

  • Assistance in project planning and experimental set-up based on scientific question
  • Evaluation of samples, photodocumentation, and report writing


Histological preparation and techniques

  • Undecalcified bone histology with or without implants (eg, metal, calcium phosphates, polymers)
  • Sectioning of resin embedded samples with specialty equipment
  • Contact radiography
  • Decalcification of tissues
  • Paraffin embedding and sectioning
  • Cryosectioning
  • Immunohistochemistry (with protocol planning)
  • Routine to special stains (for resin and non-resin embedded samples)


Microscopy and image analysis

  • Brightfield light microscopy for sections with or without implants
  • Epifluorescent microscopy for fluorochrome labelled sections (eg, bone labels, marked antibodies)
  • Macrophotography for overview images of larger samples
  • Confocal laser microscopy for optical sectioning
  • Scanning electron microscope equipped with Energy Dispersive X-Ray Spectroscopy (EDX or EDS)
  • White light profilometry for surface characterization (eg, roughness values)
  • Quantitative analysis (eg, lengths, areas, numbers) on histological samples
