Pretty sure that's the case. Since then, scientists have discovered more animals with regenerative powers. Here's how to watch. The team initially assumed that much of the enhanced wound-healing ability stemmed from Lin28a shutting off that target, let7. We knew [Lin28a] could reprogram cells back to embryoniclike stem cells but we made this other discovery largely by accident, says Daley, whose teams findings were published in the November 7 issue of Cell. Nevertheless, the discovery that the BioDome enables frogs almost completely to regrow limbs is a huge leap for science.
