Abstract

PURPOSE:

Exposition of best practice in management and experimental use of human stem cell lines in radiobiological research. This paper outlines the key challenges to be addressed by radiobiologists wishing to use human pluripotent stem cell (hPSC) lines in their research including human embryonic stem cell (hESC) lines and human induced pluirpotency stem (hiPSC) lines. It emphasises the importance of guidance already established for cell culture in general and outlines some further considerations specific to the culture of human pluripotent stem cell lines which may impact on the interpretation of data from radiobiological studies using these cells. Fundamental standards include obtaining cells from bona fide suppliers with suitable quality controls, screening cell lines to ensure absence of mycoplasma and authentication of cell lines by DNA profiling. For hESC and hiPSC lines, it is particularly important to recognise the significance of phenotypic and genetic stability and this paper will address approaches to reduce their impact. Quality assured banking of these two types of stem cell lines will facilitate reliable supply of quality controlled cells that can provide standardisation between laboratories and in the same laboratory over time.

CONCLUSIONS:

hPSC lines could play an important role in future radiobiological research providing certain fundamental principles of good stem cell culture practice are adopted at the outset of such work.
