{"groups":[{"description":"The surgical procedure is done under local anaesthesia using ultrasonic guidance and sterile technique. After receiving the MSC-suspension , the surgeon will identify the submandibular glands and inject the suspension MSCs into the submandibular gland. Calculation of injected number of MSCs pr. participant rests on the following calculation: 2.8 x 10\\^6 MSC / Cm\\^3 X volume , where volume is the volume of the submandibular gland, and a gland-volume of app. 7-8cm3 is the norm. Therefore the amount of cells given to each participant will be app. 4.6 x 10\\^7 MSC in total. Afterwards the participant will be given a band-aid and over the counter analgesics.\n\nMesenchymal stem cell: Stemcells injected into submandibularis","id":"FG000","title":"Stemcells Injected Into Submandibularis"},{"description":"The surgical procedure is done under local anaesthesia using ultrasonic guidance and sterile technique.
