Assessing kidney development and disease using kidney organoids and CRISPR engineering

Area of Science:

• Regenerative Medicine
• Developmental Biology
• Stem Cell Biology

Background:

• Kidney organoids derived from human pluripotent stem cells (hPSCs) represent a significant advancement in regenerative medicine.
• These organoids provide valuable insights into human kidney embryonic development and nephrogenesis.
• Established protocols facilitate the differentiation of renal progenitors and mature cell types.

Purpose of the Study:

• To provide an overview of kidney morphogenesis and patterning using mouse models to identify key signaling pathways for hPSC-based renal differentiation.
• To highlight the role of genome editing approaches, including CRISPR/Cas9, in understanding gene function during renal differentiation and modeling human renal diseases.
• To review the benefits of emerging technologies like single-cell RNA sequencing and discuss limitations and bioengineering solutions for kidney organoid technology.

Main Methods:

• Review of existing literature on kidney organoid differentiation protocols.
• Analysis of mouse models for kidney morphogenesis and patterning.
• Examination of genome editing techniques (CRISPR/Cas9) and single-cell RNA sequencing applications.
• Discussion of bioengineering approaches for standardizing kidney organoid models.

Main Results:

• Identification of key signaling pathways regulating renal differentiation from hPSCs.
• Demonstration of genome editing's utility in dissecting gene roles and correcting disease phenotypes in kidney organoids.
• Highlighting the impact of single-cell RNA sequencing on understanding cellular heterogeneity and developmental processes.
• Identification of current limitations in kidney organoid technology.

Conclusions:

• Kidney organoid technology, informed by developmental biology and genome editing, holds immense potential for studying kidney development and disease.
• Advancements in differentiation protocols and emerging technologies are crucial for refining these models.
• Bioengineering solutions are needed to overcome current limitations and standardize kidney organoid applications in research and medicine.
