Australian surgeon's tenacity more than skin deep.

The CEAs are sprayed, fan-like from a nozzled syringe onto severely burnt areas, prepared (ideally) with a patchwork of grafted skin. About half of the cells fall face down and grow because of the enzymes they secrete (being non-confluent), thus adhering to the recipient bed to proliferate. The beauty of Wood’s ‘spray-on skin’ (besides the speed of intervention so crucial for burns treatment), is that procuring epithelial cells from just 1 cm2 of a patient’s skin enables an area 500 cm2 to be covered.
