Kidney-on-a-Chip Models
The rapid evolution of biotechnology has ushered in a new era for organ-on-a-chip models, with the kidney-on-a-chip emerging as a groundbreaking innovation. These models harness advanced microfluidic technology to replicate the intricate architecture and function of the human kidney, offering a valuable platform for drug testing and disease modeling. At Alfa Chemistry, we are proud to deliver state-of-the-art kidney-on-a-chip models, complete with pre-qualified cells, organ-chip consumables, and validated protocols, ensuring robust characterization and functionality.
What is a Kidney-on-a-Chip Model?
- Physiological Relevance and Design
A kidney-on-a-chip model is a micro-engineered biochip designed to replicate the key physiological features of the human kidney. The primary objective is to recreate the microenvironment and intercellular interactions observed in vivo. Within the kidney-on-a-chip, cells develop an in vivo-like phenotype characterized by high differentiation, proper epithelial cell polarity, and morphology, along with functional transporter activity. These features enable more physiologically relevant analyses of kidney function, as well as the nephrotoxicity of pharmaceutical candidates.
- Key Components and Functionality
Alfa Chemistry's kidney-on-a-chip model incorporates critical renal cell populations, including primary human proximal tubule epithelial cells and renal microvascular endothelial cells. This integration facilitates realistic cell-cell interactions, setting it apart from traditional monoculture models. The chip retains essential renal characteristics, such as albumin reabsorption and stable cell morphology, for up to 14 days in culture—significantly longer than conventional cell lines, which rapidly lose differentiation.
Advantages of Our Kidney-on-a-Chip Models?
- Clinically Relevant Toxicity Assessment
Our kidney-on-a-chip models are meticulously designed to evaluate drug toxicity at clinically relevant concentrations within a human kidney co-culture system. This approach addresses the limitations of traditional animal models, which often fail to accurately predict human nephrotoxicity.
- Enhanced Cytoarchitecture and Polarization
One key advantage of our kidney-on-a-chip models is the enhanced cytoarchitecture achieved through shear stress induced by media flow. This dynamic environment promotes superior epithelial polarization, increased cell height, and pronounced cilia formation—features that are absent in static culture systems.
- Improved Transporter Activity
The inclusion of kidney-specific endothelial cells in our models significantly enhances transporter activity. For example, the sodium/phosphate (Na/Pi) co-transporter exhibits notably higher expression compared to monoculture systems or co-cultures with non-kidney-specific endothelial cells.
- Benefits of Long-Term Cultivation
Our kidney-on-a-chip models enable extended culture periods, preserving key renal functions for up to 14 days. This capability supports in-depth mechanistic studies, biomarker discovery, and assessments of nutrient metabolism. The sustained culture conditions also facilitate research into chronic kidney diseases and the long-term efficacy of drug candidates.
