Stem cells remain healthy following low-dose X-ray exposure, say biophysicists

Biophysicists have shown that following low-dose exposure to X-rays (at 80 milligrays), stem cells remain healthy, proliferate, and do not accumulate DNA damage to be passed on to their progeny. The paper was published in the journal Aging.

Overcoming Challenges of Assays of Complex Cellular Models with Real-Time Live-Cell Analysis

There's a continued drive towards making in vitro assays ever more translational towards in vivo models and ultimately the clinic. This ties in with the resurgence of phenotypic screening and is a response to the perceived poor translation of the traditional simple cell-based assays, often developed to study just single protein targets.
