Biodegradable plastics + stem cells rebuild broken bone

Scientists at the Universities of Edinburgh and Southampton in the U.K. developed an implant made of three types of biodegradable plastics and bone stem cells that helped repair and regenerate broken bone. A patient's bone marrow stem cells attach to the material and then grow new bone over time. Meanwhile, new bone replaces the plastic as it slowly degrades.  The team generated positive results in lab and in animal testing and anticipates human clinical trials. Details are published in the journal Advanced Functional Materials. Release | Abstract

Five Translational Insights Key to a Successful First-in-Human (FIH) Study – Metabolite-Based Biomarker Discovery and Validation

Translational success rates from pre-clinical animal studies to human clinical trials remain frustratingly low. Learn how metabolomics helps you bridge between the theoretical & practical, between the function & actual activity of your drug molecule to get you closer to the phenotype, sooner.
