ASSAY SERVICES
Gain insights into your anti-fibrotic drug candidates with our cell-based, Ready-2-Go or custom assay services.
WHAT IS FIBROSIS?
Thickened, stiff, damaged tissue is the hallmark of fibrosis– a deadly disease that can affect numerous organs and result from a multitude of causes. Currently available treatments are limited, only serving to improve quality of life, so drug-development efforts often target the underlying disease process to identify modulators and inhibitors of the transformation.
In addition to being categorized as a disease in itself, fibrosis is affiliated with other conditions, such as cancer and inflammatory disorders, rendering it a fulcrum point of diverse R&D studies and efforts.
CHALLENGES IN FIBROSIS RESEARCH
The history of failure of anti-fibrotic agents at clinical stages highlights the need for robust, scalable, physiologically relevant assays to maximize the potential of clinical success. Our in vitro assays model various types of fibrosis with cell-culture protocols that minimize basal fibrotic activation to offer quick, reproducible data in a predictable assay window, so you can reduce or avoid the cost- and time-prohibitive barriers inherent to animal models.

CELL-BASED FIBROSIS MODELS
We have built assays using a variety of cell types to study fibrosis, including:
- Immortalized lines (e.g., MRC-5)
- Primary human fibroblasts (e.g., lung, dermal, kidney)
- Primary, human hepatic stellate cells
- Human, iPSC-derived cardiomyocytes
- Renal proximal tubule cells
We can work with any cells that are commercially available or provided to us. Cells can be cultured in 2D or 3D formats (including bioprinted on matrices) and in monoculture or cocultured with other cell types.
Although we most commonly induce fibrosis with TGF-β, we have worked with and compared other stimulants as requested.
METRICS AND READOUTS FOR ASSESSING FIBROSIS
We can measure a variety of indicators of fibrosis, including:
- Changes in cellular morphology
- Pathway activation (e.g., phospho-SMAD nuclear translocation)
- F-actin area, intensity, alignment, length
- Alpha-smooth muscle actin-containing, stress-fiber area, intensity, alignment, length
- Extracellular matrix protein levels and/or deposition, including collagen and fibronectin
- Inflammatory cytokine secretion
