Efficacy of CRISPR-Cas9 in Mammalian Gene Therapy: A Systematic Review

Chen, L., Nakamura, K., Patel, R., & Williams, D. (2024)
Systematic ReviewGene TherapyCRISPR
Abstract
Recent advances in CRISPR-Cas9 technology have demonstrated promising results in therapeutic gene editing applications. This systematic review examines 47 preclinical studies published between 2020–2024, evaluating editing efficiency, off-target effects, and delivery mechanisms across mammalian cell types.
1. Introduction
Genome editing has become an indispensable tool in modern molecular biology[1]. Among the programmable nuclease platforms, CRISPR-Cas9 has emerged as the most widely adopted due to its simplicity and versatility[2,3].
CRISPR-Cas9 achieved 94% editing efficiency in HEK293T cells, consistent with prior reports[4].
These results demonstrate significant improvement over earlier zinc finger nuclease (ZFN) approaches, which typically achieved 40–60% efficiency[5]. However, delivery efficiency varies substantially across cell types and tissue contexts.
No significant off-target effects were observed across all tested loci[6], suggesting high specificity of the optimized guide RNA design.
CRISPR-Cas9 was superior editing efficiency compared to TALENs across tested cell types[7], including primary T-cells and hepatocytes.
The optimized lipid nanoparticle (LNP) delivery system demonstrated 78% transfection rates in primary hepatocytes[8], a notable improvement over adeno-associated virus (AAV) vector controls (61%).
2. Methods
We performed a systematic search of PubMed, Scopus, and Web of Science databases using the terms “CRISPR-Cas9” AND “gene therapy” AND “mammalian”. Inclusion criteria required peer-reviewed original research published between January 2020 and December 2024 with quantitative editing efficiency data...

Platform Components

Five primitives, infinite workflows

Unified Research Surface

One workspace for writing, reading, citations, data, and collaboration. The research equivalent of G Suite, eliminating the tool fragmentation that costs labs $10K+/year.

Credo Verification Engine

Multi-agent pipeline that audits papers at the atomic claim level. Citation checking, statistical consistency, figure-text alignment, with full evidence trails and eight verdict types.

Workflow Builder

Build custom multi-step research automations from platform primitives. Encode your lab's methodology as reusable, shareable workflows. Apple Shortcuts for the research workbench.

Shared Spaces

Researchers submit manuscripts. Reviewers see verification reports. Editors see aggregate integrity signals. Funders see compliance dashboards. Every stakeholder makes the platform more valuable for every other.

Contextual AI

Every AI interaction is grounded in what you're currently working on. Not a chatbot, but an ambient intelligence layer aware of your full research state, citations, data, and manuscript context.

Verification Engine

Every claim. Every citation. Every figure. Verified.

Claim-Level Atomic Verification

Credo decomposes papers into individual claims and verifies each one against retrieved evidence. Eight verdict types, from verified to disputed, with confidence levels and full audit trails. No document-level hand-waving.

Verification Report
12 claims extracted
Verified

CRISPR-Cas9 achieved 94% editing efficiency in HEK293T cells

Evidence

Zhang et al. (2023) reports 92-95% efficiency in HEK293T using optimized sgRNA, consistent with manuscript claim.

DOI:10.1038/s41587-023-01842-w · Confidence: High
Caution

No significant off-target effects were observed across all tested loci

Evidence

Source reports "minimal off-target activity" not "no significant effects." Overgeneralization detected.

DOI:10.1126/science.adg7285 · Confidence: Medium
Disputed

Demonstrated superior editing efficiency compared to TALENs across tested cell types

Evidence

Kim et al. (2022) found TALENs outperformed CRISPR-Cas9 in primary T-cells (82% vs 71% efficiency).
