AACR late breaking abstract13 Apr 2018 23:47
Looks like a late breaking abstract featuring research using Parsortix has been published and will be presented at AACR on Wednesday - link below.
It appears to be completely independent research from Northwestern University, Chicago on culturing breast cancer CTC's captured by the Parsortix system.
'Using the Parsortix System, highly purified CTCs (ranging in number from 300 to 17,250 cells) were isolated from the blood samples for each of the 16 patients and placed into culture (day 0). During the first week, the CTCs could be expanded to 3.5 - 5.5 fold, and then to 9.5 - 22.5 fold during the second week, to maximum amount of 112,500 within 14 days'
'We identified and optimized a workflow for the recovery and culturing of CTCs from Stage III/IV BCa patients, demonstrating that cell-size dependent isolation using the Parsortix System allows for effective ex vivo culture. With further optimization, this strategy may be utilized for organoids development for drug testing and molecular analysis, representing an important tool for personalized precision therapy.'
So capturing live circulating tumour cells from breast cancer patients and basically growing them in the lab - amazing and of course not possible with ctDNA liquid biopsies.
