Columbia researchers bioprint seamless 3D skin grafts for burn patients
The science of grafting skin has come a long way from the days of scraping it off one part of a patient's body and slapping it back on somewhere else to cover a nasty burn or injury. These days grafts are commonly bioprinted like living inkjets using the patient's cultured cells to seed the growing process,. The primary shortcoming of these printed grafts is that they can only be produced in flat sheets with open edges.
What's more, these uniform grafts have shown superior performance, both mechanically and functionally, than their patchwork alternatives. The Columbia team has dubbed the grafts"wearable edgeless skin constructs" . Ok, but can you eat them?
