Building a new skull

Yesterday, Dr. MINIMCOM sent in a team of VIRUS-based constructor units into Rei's bloodstream. MINIMCOM ordered them to cluster around the fracture in Rei's arm. He then used a miniature null-fold projector to transport random bone cells from other parts of Rei's arm into the cavity and the constructors fitted them together like puzzle pieces. At this point, Rei's arm has been completely reconstructed and the bone just needs to set. Today, MINIMCOM is going to try and heal the hole in Rei's skull using a more advanced version of the same technique:

     MINIMCOM removed the bandages and packing from the back of Rei’s skull. Rome gasped at the size of the wound. The portion of Rei’s skull that was missing was a full two inches in diameter. His living brain was exposed, the grey matter pulsing with his heartbeat. Only a thin plastic film covered the area. MINIMCOM removed it and cerebrospinal fluid started gushing out for a moment then the tiny flood stopped. MINIMCOM held it at bay with an outstretched hand and a small null-fold twist.
     “I will place a thin bio-polymer film underneath the remaining bone,” MINIMCOM said. “I have coated both sides with an arteriogenic compound that should cause new blood vessels to form. This will help in the healing process. The film will also prevent Rei’s brain from leaking any more fluid.”
     Mercifully, the film that MINIMCOM placed over the wound was opaque such that Rei’s exposed brain was no longer visible. MINIMCOM retrieved the syringe with the grayish liquid. However, instead of injecting Rei, MINIMCOM merely expelled a few drops of the fluid with enough force that despite the lack of gravity, they spread evenly across the film, held in place by surface tension.
     “First, the dura mater,” MINIMCOM said. Cells from all over Rei’s skull were transported to the film and assembled by the VIRUS units. Soon a visibly thickened layer of tissue was formed.
     “Won’t removing the tissue from other parts of his head cause damage?” Rome asked, even as she watched the fascinating display.
     “No,” MINIMCOM said. “I am taking less than .01% of the cells from any given area. Any micro-perforations this causes will heal instantaneously. No section will even miss them.”
     Rei grunted.
     “Am I causing you pain?” MINIMCOM asked with some concern. “I can apply an anesthetic if you need it.”
     “No,” Rei said. “It’s just a little weird being your science experiment. I’m fine. Keep going.”
     MINIMCOM nodded. Layer by layer, MINIMCOM built up the tissues culminating in a fibrous bony surface covered by muscle. Finally, MINIMCOM took tiny sections of Rei’s scalp and knit them together, closing the wound completely. In another age, it would be considered the ultimate in hair-plugs.
     “That’s amazing,” Dr. Martell said, bending over to inspect the repairs. “If I hadn’t seen the wound myself, I’d swear it was never there.”

Wow. Don't you wish our doctors had the ability to do this today? I even impressed myself. Now that this is a proven good technique, it is time for the main show, i.e. healing Rei's back.
