Control staining sample staining
The concept:
1. Define your region of interest
2. Count all cells.
3. Evaluate each individual marker for all detected cells.
4. Generate scattergrams or histograms
to quantify and compare positive and negative cells.

Forward connection: from image to scattergram
The „Forward Connection“ feature allows to double click on
individual cells in any image in order to show its position in
the scattergrams, i.e.to show a cell‘s properties.

Feulgen Staining of Colon Carcinoma – Overview
At 40x magnification a total of 1464 field of view was scanned.
Slide Overview at 2.5x Magnification
Application:Leukocyte Cytokine Expression in situ
Chang-Rodriguez et al.2004, Journal of Leukocyte Biology 76(3):657-66
Aim:
Quantify the expression of Interleukin-10
of dermal leukocytes in a knock-out
mouse model. Different mice (adult,
newborn and knock-out) were used to
determine the IL-10 expression level in
situ and thereby learn to understand
developmental changes throughout the
ontogeny of the mouse immune system.
It could be demonstrated that autocrine
IL-10 partially prevents differentiation of
neonatal dendritic epidermal leukocytes
into Langerhans cells

TissueQuest algorithms dynamically search for nuclei which are
• isolated or in close proximity
• intensly or weakly stained
• large or small
• round or elongated
• compact or ring shaped
• in focus or somewhat blured (beause they are in a different focus plain)

TissueFAXSThe Microscopic Equivalent to Flow Cytometry
Application Notes
Application Note 1:Measurement of Neuronal Markers
Courtesy Prof. M. Maurer, Inst. f. Pathophysiologie, Univ. of Heidelberg, Germany
Aim:
Measure the moleular expression levels of certain markers in neuronal cells in a rat model.
1,87%
Red: nuclei (Propidium Iodide)
Green: neuronal marker
Application Note 2:Viability Testing in Cell Cultures
Courtesy Dr. Schenkel, Central Mouse Facility, DKFZ Heidelberg, Germany
Aim:
Quality control of sperm cells after
thawing. By applying a specific stain
that labels exclusively nuclei of live
cells and a second stain that
exclusively labels nuclei of dead cells
an automated viability test can be
established by using TissueFAXS™.
Please note: The single event in the upper right
quadrant is a doublet of a living and a dead cell
tightly sticking together and can be easily gated out.
Why?
Why do we need biomedical image analysis?
• The human brain is a potent interpolater that can hardly be
replaced by software!
• An experienced observer is much faster than a computer!
• What could a computer „see“ in an image that a human
observer cannot recognize?
• What does it help me to know how many tumor cells are
there? All I need to know is whether there are any tumor cells!
