Why and how do wounds heal? Scientists have only recently begun to address these questions and are now developing techniques to prevent scars that are disfiguring. Their work should also give hope to people suffering from persistent wounds, like ulcers, notorious for being constantly painful during the long healing process. "Recommended. This documentary addresses the current state of technology related to developments in wound healing and scar prevention. It explains the use of technologies, such as digitized optical scans, MRIs, and ultrasound; then scientists discuss the healing process; it also explores areas such as artificially creating skin from seed cells, embryonic healing verses normal cell healing, anti TGF Beta promotion of wound healing, plus the use of specially grown/produced substances (fungal and blood protein based), which assist in the scar prevention/healing process. It is well produced and recommended for collections focusing on current scientific/technological issues." -EMRO Review
