Definiens Tissue Studio™ 2.0 – the solution of choice for tumor biomarker
and morphological profiling
Definiens Tissue Studio™ 2.0 is the solution of choice for tumor biomarker and
morphological profiling because it is easy to use, accurate, robust, powerful and fast.
Definiens Tissue Studio™ 2.0 provides localized, cell-by-cell biomarker analysis; as well as
relational and multiparametric morphological quantification of cells and sub-cellular
structures. Whether you are working with bright field or immunofluorescence images;
on whole tissue slides or tissue microarrays; Definiens Tissue Studio™ 2.0 is your ultimate
resource for comprehensive digital pathology image analysis.
Figure 1 Definiens Tissue Studio™ 2.0 now fully
supports immunofluorescent image quanti­
fication. In this example, nuclei are detected in
xenograft tissue stained for DAPI, CD206, CD68
and a therapeutic antibody candidate. Up to 12
channels are supported.
Understanding Images

2. Definiens Tissue Studio™ 2.0 supports most commercial image formats
Definiens Tissue Studio™ 2.0 supports native image file formats from most
commercially available digital slide image acquisition systems. This enables
laboratories to standardize on one image analysis platform improving productivity
and reproducibility. Definiens Tissue Studio™ 2.0 also supports .tiff, .jpeg, .bmp and
.jpeg2000.

file formats from most commercially
available image acquisition platforms.
A single platform for bright field and immunofluorescence image
analysis
Simply start the program, and choose whether you want to analyze bright field or
immunofluorescence images; in either slide or tissue microarray formats. There is no
need for additional software.
Figure 3 After launching the program,
the user selects four analysis modes:
Bright field (slides or TMAs); or
immunofluorescence (slides or TMAs)
Definiens Tissue Studio™ 2.0 provides a simple to use, 4-step workflow
Load, Configure, Run, Review. It is that easy. New users can expect to develop a
customized image analysis solution in about 20 minutes. Simply load your training

results. The exported results are contained within easy to access folders and include
per-object information, classified images and more.

The Analysis Builder is the heart of
Definiens Tissue Studio™ 2.0. It combines
advanced image analysis technology
with a simple and efficient user interface;
providing flexibility for configuring
robust solutions over a wide variety of
stains and tissue types. The user sets
parameters for detecting regions of
interest; cellular and sub-cellular analysis
within these regions; and various data
export options.

configuration panel makes it easy to develop a
customized image analysis solution.
Region of interest detection with Definiens
Composer™ technology – Interactive, simple,
accurate, and reliable
Definiens Composer™ technology is an easy to use
method for generating robust region of interest
detection. In this “learn by example” format, you
simply use the paintbrush tool to “brush” on
representative regions of interest, and then click
the “learn” button. It is that easy. New in Definiens
Tissue Studio™ 2.0 is the ability to tune Definiens
Composer™ technology for even more precise
region of interest detection.

technology in action – In this image,
all staining for Her2 in breast tumor
tissue has been classified in orange;
surrounding tissue, yellow; and white
space, blue.
For manual annotation, the Magnetic Snap tool helps to follow the contours
of a region of interest; making manual annotation quick and easy. The Magnetic Snap
tool can be used in combination with Definiens Composer™ technology.

Definiens Tissue Studio™ 2.0 allows accurate detection of cells and
sub-cellular components
After region of interest training with Definiens Composer™ technology, subsets are
selected (i.e., from tumor regions), to configure the system to properly identify cells
and sub-cellular objects (membrane, cytoplasm, nuclei). It only takes a few interactive
steps to properly adjust the software for accurate detection of cells and sub-cellular
structures.

preview of the detection of cells and
sub-cellular structures in breast tis­
sue. In this step, the user interactively
adjusts the software until the desired
result is achieved.

5. The next configuration step is to set the staining thresholds for biomarker
quantification. Although the software makes suggestions for default low, medium, and
high thresholds, this step is ultimately user defined which ensures accurate cell-by-cell
evaluation of biomarker expression.

intensity preview (low, medium, or high). As in figure
9a, the user interactively adjusts the software until
the desired result is achieved. The solution is saved
aa and batch processing can now begin.
Definiens Tissue Studio™ 2.0 is also able to exclude cells from the analysis. In Figures
9a and 9b, all cells where nuclei were not present have been excluded from further
analysis. You can exclude cells based on area, length, width, distance from border, etc.
The most comprehensive biomarker and morphological quantification
available for digital pathology image analysis
Increasingly, the trend in the literature shows that in addition to localized biomarker
expression, tumor morphology plays a role in disease prognosis or therapeutic
response prediction. Definiens Tissue Studio™ 2.0 provides the world’s most
comprehensive digital pathology image analysis for tumor morphological quantification.
Figure 10 The image object table and
image object information tables are
displayed. Clicking on any object (cell,
nucleus, cytoplasm, region of interest,
etc.) will yield all quantified features for
that particular object.
Length, area, width, elliptic fit, circularity, and dozens more intensity-, shape- and
context-based features can be measured. You can even create your own attributes to
quantify, and there is no limit to how many parameters can be measured
or exported. Further, there is no “speed limit” for comprehensive image analysis
processing. Turnaround times are the same whether you are measuring marker
intensity; percent stain; percent positive or negative nuclei; or for example, 15 different
morphological attributes of an individual cell.

from a typical Definiens Tissue Studio
analysis. Over 50 intensity-, shape-, and
context-based features are available.
Full tissue microarray support for retrospective studies
Tissue microarrays are often utilized for retrospective studies involving tumor
biomarker and morphological profiling. In these settings, researchers look for
correlations between biomarker expression, tumor morphology, and clinical
endpoints of interest. Definiens Tissue Studio™ 2.0 provides full tissue microarray
support, for both bright field and immunofluorescent images, and supports
metadata import on a per core basis. Even with heavily skewed tissue microarrays,
Definiens Tissue Studio™ 2.0 easily matches cores.
Figure 12 a-d In these images, a non-small cancer tissue microarray was analyzed for the nuclear expression of SOX2. The study
concluded that SOX2 over-expression correlates to longer survival in patients with squamous non-small cell lung cancer (Images
