Researchers have developed “designer tissue” with Velcro-like qualities to mend damaged hearts.

Heart cells are grown on hook and eye mesh that attach to one another, allowing tissue to be rebuilt one layer at a time. The mesh then dissolves away and after just four days the new tissue was shown to contract on its own in rats.

If scientists can re-grow cardiac tissue, more complex tissue like skin or liver may be next. Thank you to our furry heroes for this amazing research!
