Clinical-Grade Isolated Human Kidney Perivascular Stromal Cells as an Organotypic Cell Source for Kidney Regenerative Medicine.

ABSTRACT: Mesenchymal stromal cells (MSCs) are immunomodulatory and tissue homeostatic cells that have shown beneficial effects in kidney diseases and transplantation. Perivascular stromal cells (PSCs) identified within several different organs share characteristics of bone marrow-derived MSCs (BM-MSCs). These PSCs may also possess tissue-specific properties and play a role in local tissue homeostasis. We hypothesized that human kidney-derived PSCs (hkPSCs) would elicit improved kidney repair in comparison with BM-MSCs. Here we introduce a novel, clinical-grade isolation method of hkPSCs from cadaveric kidneys by enriching for the perivascular marker, NG2. hkPSCs show strong transcriptional similarities to BM-MSCs but also show organotypic expression signatures, including the HoxD10 and HoxD11 nephr
