MicroRNAs (miRNA) comprise a group of short ribonucleic acid molecules implicated in regulation of key biological processes and functions at the post-transcriptional level. Ionizing radiation (IR) causes DNA damage and generally triggers cellular stress response. However. the role of miRNAs in IR-induced response in human embryonic stem cells (hESC) has not been defined yet. https://www.tamalpies.com/product-category/tracer-pellets/
