Abstract:
Selected renal cells (SRCs), a renal epithelial cell-enriched platform, are being advanced as an autologous cell-based therapy for the treatment of chronic kidney disease. However, the mechanism underlying its renal reparative and restorative effects remains to be fully elucidated. In this study, we coupled knowledgebase data with empirical findings to demonstrate that genes differentially expressed by SRCs form interactomes within tubules and glomeruli and mediate a suite of renal developmental activities including epithelial cell differentiation, renal vasculature development, and glomerular and nephron development. In culture, SRCs form organoids which self-assemble into tubules in the presence of a scaffold. Implanted into the kidneys of subtotally nephrectomized rats, SRCs are associated with comma- and S-shaped body cell formation and glomerular development, and improvement in renal filtration indices and renal microarchitecture. These data suggest that SRCs harbor nephrogenic potential, which may explain, at least in part, their therapeutic activity.
Insights
Selected renal cells (SRCs) show potential for chronic kidney disease treatment by promoting kidney development and repair. These cells form tubules and aid in glomerular development, improving kidney function in preclinical models.
Area of Science:
- Nephrology
- Regenerative Medicine
- Cell Biology
Background:
- Selected renal cells (SRCs) are a promising autologous cell therapy for chronic kidney disease (CKD).
- The precise mechanisms behind SRCs' renal reparative effects require further investigation.
Purpose of the Study:
- To elucidate the molecular mechanisms and functional potential of SRCs in renal development and repair.
- To investigate the therapeutic efficacy of SRCs in a preclinical model of kidney injury.
Main Methods:
- Integrated knowledgebase data with empirical findings to analyze SRC gene expression.
- Cultured SRCs to form organoids and assessed their self-assembly properties.
- Implanted SRCs into subtotally nephrectomized rats to evaluate in vivo effects on renal structure and function.
Main Results:
- SRC genes form interactomes involved in renal development, including epithelial differentiation and vascularization.
- In vitro, SRCs self-assembled into tubular structures within scaffolds.
- In vivo, SRCs promoted comma- and S-shaped body formation, glomerular development, and improved renal filtration and microarchitecture in rats.
Conclusions:
- SRCs possess nephrogenic potential, contributing to renal development and repair.
- These findings provide mechanistic insights into SRC-based therapies for CKD.
- SRCs demonstrate therapeutic promise for restoring kidney structure and function.

Proximal Convoluted Tubule (PCT):
The PCT is the initial segment of the renal tubule, extending from the Bowman's capsule that encloses the glomerulus. Its convoluted structure and microvilli-lined cells increase the surface area for reabsorption. The PCT reabsorbs glucose, amino acids, sodium, and water from the filtrate, ensuring essential...
