Strip of tape with dissolvable microneedles

“. . . researchers [at the Terasaki Institute in Los Angeles, and UCLA] made microneedles out of the gelatin matrix, complete with MSCs. These were then encased in a shell made of a tougher biomaterial called PLGA. Once embedded in a wound, the PLGA dissolves first, and as it does the microneedles begin to poke out between the cracks, allowing them to deliver their payloads. In lab tests, 90 percent of the MSCs were still alive and functioning 24 hours later.” MORE
