Could the PD community benefit from such cases? I liked the fact that they used a new type of syringe.
"“You can’t teleport cells into a brain,” Schweitzer said. You need a needle that delivers the cells to a precise spot and does so without squeezing them. Yet in some previous cell therapies, “more than 90% of the cells died shortly after transplantation,” Schweitzer said, probably because the needles plunged the cells into the brain as one big ball. That gave the cells no access to oxygen or nutrients.
Schweitzer therefore developed a motor-driven syringe “to keep the cells from blasting out the bottom of the needle” in one blob, he explained, and instead deposit them “as you draw out the needle.” He worked with the manufacturer to build an off-the-shelf syringe that would extrude 2 microliters of cells per minute into the tract created when the needle entered. When they tried it in rat and pig brains, the syringe left behind a nice line of cells with access to nutrients and oxygen."
Maybe some other trials would have been more successful if they used this type of syringe.
