Spray-on skin is a patented skin culturing treatment for burns victims, developed by scientist Marie Stoner and plastic surgeon Dr Fiona Wood of Perth, Western Australia. Wood's treatment is under ongoing development. Where previous techniques of skin culturing required 21 days to produce enough cells to cover major burns, Wood has reduced the period to five days. Through research, she found that scarring is greatly reduced if replacement skin could be provided within 10 days. Dr Wood's reported goal is "scarless woundless healing".
Wood established a company called Clinical Cell Culture (C3) in 1993 to commercialise the procedure. Her business came about after a schoolteacher arrived at Royal Perth Hospital in 1992 with petrol burns to 90% of his body. Wood turned to the emerging US-invented technology of cultured skin to save his life, working nights in a laboratory along with scientist Marie Stoner. The two women began to explore tissue engineering and moved from growing skin sheets to spraying skin cells. 
As well as receiving praise from both her own patients and the media, she also attracted controversy among other burns surgeons because spray-on skin had not yet been subjected to clinical trials. A clinical trial is planned at Queen Victoria Hospital, England.
