Abstract The renal biopsy provides critical diagnostic and prognostic information to
clinicians including cases of acute kidney injury, chronic kidney disease, and
allograft dysfunction. Today, biopsy specimens are read using a combination of
light microscopy, electron microscopy, and indirect immunofluorescence, with a
limited number of antibodies. These techniques all were perfected decades ago
with only incremental changes since then. By contrast, recent advances in
single-cell genomics are transforming scientists' ability to characterize cells.
Rather than measure the expression of several genes at a time by
immunofluorescence, it now is possible to measure the expression of thousands of
genes in thousands of single cells simultaneously. Here, we argue that the
development of single-cell RNA sequencing offers an opportunity to describe
human kidney disease comprehensively at a cellular level. It is particularly
well suited for the analysis of immune cells, which are characterized by
multiple subtypes and changing functions depending on their environment. In this
review, we summarize the development of single-cell RNA sequencing
methodologies. We discuss how these approaches are being applied in other
organs, and the potential for this powerful technology to transform our
understanding of kidney disease once applied to the renal biopsy.
