How do you ensure the animal models accurately reflect human disease?

We are comparing the gene expression profiles of our models against known human disease signatures. This ensures that the biological pathways your drug targets are active and relevant in our models.

Can you accommodate custom study designs for novel delivery methods?

Sure. We frequently handle specialized delivery routes, including intra-articular injections, local scaffold implantation, and osmotic pump installation for continuous infusion.

Do you offer longitudinal data collection?

Yes. Through non-invasive imaging, we can track the same animal over multiple time points, providing powerful internal controls and reducing the total number of animals required.

How do I get started with a pilot study?

Overview of Musculoskeletal Disease Models

The musculoskeletal system is an intricate network of bones, muscles, tendons, ligaments, and cartilage that provides structure, support, and locomotion. Disorders within this system, ranging from osteoporosis and sarcopenia to osteoarthritis and rare genetic dystrophies, represent a massive global clinical burden, often leading to chronic pain and permanent disability. Musculoskeletal Disease Modeling involves the use of specialized rodent strains and induction techniques to replicate these human pathologies. These models are essential for understanding disease mechanisms and evaluating the efficacy of therapeutic interventions in a controlled, measurable environment.

Musculoskeletal Disease Models

Creative Biolabs offers a robust portfolio of validated models designed to simulate the full spectrum of musculoskeletal pathology. We utilize a combination of genetic engineering, surgical induction, and chemical interventions to create highly reproducible disease states. Our capabilities include various models, which are rigorously validated to ensure they meet the specific mechanistic requirements of your therapeutic candidate.

Published Data

Objective: To determine if molecular signatures of sarcopenia are conserved across species and can be used to validate rodent models for human translation.

Model Used: Multi rodent comparison (Mice and Rats) anchored by phenotypic measurements (Grip Strength and Fiber Type analysis).

Results: The study identified a core set of conserved genes across mice, rats, and humans related to mitochondrial function and proteostasis. Results demonstrated that chronological age is a secondary predictor of phenotypic loss; molecular changes correlate most strongly with actual muscle mass loss. This confirms that focus on phenotypic anchoring ensures superior translational predictive value for human clinical trials.
