A tiny chip can directly repair corrupted tissue

A new device, a chip essentially the size of a fingernail, can repair damaged organs in , heralding a major development in medical science.

chip

Developed at the University of Ohio, it is named Tissue Nanotransfection (TNT) or in free Greek translation micro-transplant web, and uses a small chip of silicone the size of a coin that "injects" genetic code into skin cells, promoting them from one species to another.

During the initial testing phase, μπόρεσαν να επαναπρογραμματίσουν σε ένα ποντίκι που είχε ένα άσχημα τραυματισμένο πόδι χωρίς ροή αίματος , κύτταρα του δέρματος σε αγγειακά κύτταρα. Εντός μιας εβδομάδας ενεργά αιμοφόρα αγγεία εμφανίστηκαν γύρω από το πόδι και μέσα σε δύο εβδομάδες το πόδι είχε αποκατασταθεί πλήρως. Επίσης ένα ποντίκι που είχε υποστεί εγκεφαλικό αποκαταστάθηκε, υποδηλώνοντας αυτή η τεχνολογία μπορεί να εφαρμοστεί σε όργανα και νευρικά κύτταρα, καθώς και ιστούς. Είναι η πρώτη φορά που κύτταρα έχουν επαναπρογραμματιστεί σε ένα ζωντανό οργανισμό.

The technology weighs less than 100 grams and has a long life. It is completely non-invasive (no surgery or micro-surgery) – the genetic code is given to the device with a small electrical which is barely noticeable to the patient – ​​and the procedure can be performed without access to a laboratory or hospital. This means it will have a significant impact on the lives of those dealing with medical emergencies where time is of the essence, such as car accident victims and soldiers wounded in combat. It is awaiting approval from the US FDA, but researchers expect human trials to begin within the year.
