“…These independent or combined "single" technologies have helped us not only to create a high-resolution SC type map of human tissues [127] and three-dimensional nuclear architecture, gene expression, and epigenetic modifications, [128] but also to assess and analyze immune cell differentiation, [129,130] to uncover cellular and molecular mechanisms and to discover new therapeutic targets for human diseases, [49,[131][132][133] in particular COVID-19 and CVDs, as well as to trace cancer progression. [134] It can be said that this is indeed a new "single" era of biomedicine and its current implications and research in both CVDs and COVID-19 [135][136][137][138][139][140][141][142][143][144][145][146][147][148][149][150] as well as others will definitely open a new beautiful future.…”
