To undergo cultured stem cell therapy, blood and skin tissue are first taken, and the stem cells contained within are extracted and cultured.
Cultivation takes about a month, after which the stem cells can be administered via intravenous infusion, which is administered slowly over approximately 40 to 60 minutes.
The skin sampling is performed under local anesthesia, and the sensation is similar to that of dental treatment. The sample area is small, about 5mm, and the scar becomes almost invisible after about a month.
