Tracing the cellular origins of renal tubular regeneration

WT1+ glomerular parietal epithelial progenitors promote renal proximal tubule regeneration after severe acute kidney injury

Lineage tracing and single-cell sequencing in a mouse model of severe acute kidney injury supported the contribution of WT1-positive glomerular parietal epithelial progenitor cells to proximal tubule regeneration.

What this study examined

• Mouse ischemia–reperfusion injury, conditional gene knockout and lineage tracing
• Newly formed tubular cells showed albumin uptake at the 30-day stage

Why the study matters

Tracing where repair begins: identifying WT1-positive progenitor cells that contribute to proximal tubule regeneration.
