abstract = {DNA-double strand break (DSB), detected by immunostaining
of key proteins orchestrating repair, like γH2AX and 53BP1,
is well established as a surrogate for tissue
radiosensitivity. We hypothesized that the generation of
normal brain 3D organoids ('mini-brains') from human induced
pluripotent stem cells (hiPSC) combined with detection of
DNA damage repair (DDR) may hold the promise towards
developing personalized models for the determination of
normal tissue radiosensitivity. In this study, cerebral
organoids, an in vitro model that stands in its complexity
between 2D cellular system and an organ, have been used. To
quantify radiation-induced response, immunofluorescent
staining with γH2AX and 53BP1 were applied at early (30
min, initial damage), and late time points (18 and 72 h,
residual damage), following clinical standard 2 Gy
irradiation. Based on our findings, assessment of DDR
kinetics as a surrogate for radiosensitivity in hiPSC
derived cerebral organoids is feasible. Further development
of mini-brains recapitulating mature adult neuronal tissue
and implementation of additional signaling and toxicity
surrogates may pave the way towards development of
next-generation personalized assessment of radiosensitivity
in healthy neuronal tissue.},
