Here is one link: https://www.sciencedaily.com/releases/2019/10/191031174650.htm . I was not able to find the one I was actually reading earlier (and apparently my poor sleep last night was not sufficient and I cannot remember how I found it....) but the link here seems to be referencing the study I was reading about.
BTW, when I mentioned “external” I was not thinking external to the organism (e.g., me) but rather external to the cells (or at least many of them) but within the confines of our body or organ.

Aha, that study linked to the one I was thinking of: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3880190/
Thanks!
