Study shows that grafted limb cells acquire molecular 'fingerprint' of new location

Cells triggering tissue regeneration that are taken from one limb and grafted onto another acquire the molecular "fingerprint," or identity, of their new location, UC Irvine developmental biologists have discovered. The findings provide a better understanding of how grafted tissue changes its identity to match the host tissue environment during the process of limb regeneration and bring scientists closer to establishing regenerative therapies for humans. The results also challenge the conventional assumption in regeneration biology that cellular properties are predetermined... via Health News from Medical News Today Read More Here..
