Visikol Inc

Visikol has an in-house 3D cell culturing capability and works with clients to generate models that meet their specific cost, throughput, in-vivo relevancy and validation requirements. Visikol recognizes that 3D cell culture models are not a one-size-fits-all tool and that these models need to be developed specifically for each assay. We partner closely with clients to determine the best type of model for their specific research question and testing requirements. Some assays can utilize inexpensive single cell type spheroids to better replicate the in vivo microenvironment where other assays might require highly complex multi-cell-type models.

After we have generated a model for a client or brought a model in from a 3rd party, we can run full screening campaigns with simple plate reading all the way to high content confocal assays with advanced image processing and multi-channel immunolabeling. We are the only CRO capable of characterizing 3D cell culture models in their entirety through our patented Visikol HISTO-M tissue clearing technology and our clients consider us the industry leader in 3D cell culture characterization.

Vasculature is a complex three-dimensional feature which is challenging to depict and evaluate using traditional two-dimensional histology. Through using our patented Visikol HISTO tissue clearing technique combined with fluorescent labeling and 3D imaging (confocal and light sheet microscopy), we are able to visualize vasculature in 3D. When analyzed with our digital pathology algorithms, we are then able to transform these 3D vasculature networks into quantitative end-points (volume, branching) for your studies. This allows for researchers to quantitatively assess the impact of a compound or antibody on the angiogenesis process. We can conduct in depth vasculature studies on a few tissues at a time or screens on hundreds of tissues.

We have offer fee-for-service 3D tissue labeling and imaging. Our standard service consists of 1 mm tissue section labeling and imaging where you send us a tissue and we send back a digital stack of optical Z-sections from your tissue.

Our standard service is comprised of:
- 10X magnification imaging with 10 um Z steps.
- Nuclear label plus one antibody label (from list of Visikol HISTO validated antibodies).
- USB stick shipped back to customer
- Two week turnaround time

We can also conduct up to four channel imaging and can optimize antibody labeling for new antibodies.

At Visikol our core focus is on advanced optical imaging and digital image analysis to provide researchers with quantitative and actionable insights as a service. We have developed a portfolio of digital pathology tools that we use to help you transition from qualitative to quantitative histopathology analysis. Typically, clients will send us tissues, slides or just digital files and we will work with the client to answer a specific research question such as developing a quantitative quality control assay or quantifying the specific phenotypic effect of a drug compound. We offer a full spectrum of digital pathology solutions including:

• Customizable feature extraction for morphology of interested
  
• Automated feature quantification from digital pathology slides using 3Screen software.
  
• Reproducible and accurate quantitative data for developing quality control assays, dose response effects and addressing complex biological questions.
  
• Suite of algorithms that include: co-localization, area analysis, H-score, biomarker analysis, intensity thresholding and structure differentation.
  
• Generation of multi-dimensional data outputs that can be processed using 3Screen clustering analysis.
  

Through our suite of digital pathology tools we can extract thousands of features (e.g. nuclei size, distribution etc) from slides instantaneously. This means that complex questions and quantitative assays (e.g. transplant quality control) can be developed where traditionally a qualitative approach would be limited. The shift to quantitative histology means that for your drug discovery and pre-clinical efforts that quantitative fingerprints can be developed for your tissues that allow ranking and comparison across hundreds of dimensions (e.g. necrosis, cell death). We also understand that the jump to digital pathology can be big for many research groups that have relied on traditional histopathology and therefore we typically begin all of our service projects with short and inexpensive pilot studies so you can quickly see how digital pathology fits into your research workflow.

How our services work:

1) Define your research question, morphological features and desired end-points.
2) Send Visikol slides for slide scanning or digital renderings of slides.
3) Visikol extracts key features from digital renderings and analyzes based upon research question.
4) Visikol returns quantitative analysis report back to the customer.

At Visikol our main focus is on transforming tissues into three-dimensional data sets that can be analyzed for actionable insights. We have developed a suite of Visikol HISTO tissue clearing reagents that we sell to researchers as well as use within our portfolio of imaging and image analysis assays. We have developed our Visikol HISTO-1 and Visikol HISTO-2 reagents for use with whole tissues (e.g. mouse brains) and to be compatible with immunolabeling and fluorescent protein. Additionally, we have developed our Visikol HISTO-M tissue clearing reagent to be compatible with 3D cell culture models (e.g. organoids, spheroids, microtissues) and high-throughput process. The Visikol HISTO reagents are also reversible which means that 3D imaging can be followed up with traditional histopathological analysis.

If you are interested in using tissue clearing in your lab you can purchase our Visikol HISTO tissue clearing reagents or send us tissues to label, clear, image and analyze. Our Visikol HISTO Starter Kits start at $489.99 and our services start at $499.99 per sample.

We currently offer a suite of best-in-class 2D and 3D in vitro high content screening assays and are the only CRO capable of complete 3D cell culture characterization through the use of our patented tissue clearing technology.

Visikol is a CRO that is focused on transforming images into insights through the use of advanced optical imaging modalities and digital image analysis. We have developed a suite of automated image analysis tools that we leverage to assist our clients with their image analysis projects. Typically, clients send us either physical tissues that we transform into digital data sets or digital data sets that we analyze based upon a clients specification. Additionally, we have worked with clients to develop and implement custom automated image analysis algorithms for on-site applications. Our team are experts in image analysis and regularly work with traditional histopathology files (e.g. H&E, IHC) as well as images from optical coherence tomography (OCT) and computed tomography. However, we are agnostic in our approach to image analysis and can develop customized solutions for novel applications.
