The delicate subtleties. Didn’t Sawston do some additional work with their cryopreservation unit not too long ago? Dr Liau and regulators would be made aware of any desire to save tumor tissue by Dr Ashkan if he did not communicate directly with NWBO. Then, of course, regulators being in communication with NWBO would probably forward that desire as a staged manufacturing “roadblock” to ensure adequate ramp up for what they may anticipate as an SOC viable treatment right?; ). Best wishes.
