We provide you with the latest breaking news and videos straight from the Biotech industry. Analyzing molecular clocks in the form of nonenzymatically deamidated proteins, we unmasked a position-dependent gradient (distal high, proximal low) of protein turnover, indicative of a gradient of tissue anabolism reflecting innate tissue repair capacity in human lower limb cartilages that is associated with expression of limb-regenerative microRNAs. Whereas, the knee had moderate amounts and the ankle very few proteins with these chemical modifications. Further, when the limbs that could not regenerate were studied further, researchers again found extensive scar tissue build-up, paralleling what is often seen in human injuries. A new study published in Science Advanceshas uncovered a previously unknown capacity for cartilage regeneration in human lower limbs.
