Efficient genome editing of differentiated renal epithelial cells

Area of Science:

• Molecular Biology
• Genetics
• Cell Biology

Background:

• Genome editing technologies allow precise DNA manipulation.
• Previous methods were limited to non-differentiated or haploid cells.
• Editing differentiated renal cells faced challenges in construct design, expression, mutation rates, and screening.

Purpose of the Study:

• To develop an easily implementable workflow for genome editing in differentiated renal cells.
• To generate targeted heterozygous and homozygous genomic alterations.
• To create novel cellular and animal models for kidney disease research.

Main Methods:

• Utilized transcription activator-like effector nucleases (TALENs) and clustered regularly interspaced short palindromic repeat (CRISPR) systems.
• Developed a workflow for efficient expression of genome editing constructs.
• Established screening strategies for identifying desired mutations.

Main Results:

• Successfully generated targeted genomic sequence alterations in renal cells.
• Created novel cellular models for studying autosomal dominant polycystic kidney disease (ADPKD).
• Validated the applicability of the method to mouse embryonic stem cells (mESCs) for generating mouse models.

Conclusions:

• The presented workflow enables rapid and precise genome editing in differentiated renal cells.
• This approach facilitates the generation of disease models for studying kidney physiology and pathophysiology.
• The method is broadly applicable to various cell types for genotype-specific functional studies.
