Gene editing in hematopoietic stem cells by co-delivery of Cas9/sgRNA ribonucleoprotein and templates for homology-directed repair in 'all-in-one' lentivirus-derived nanoparticles.
Article in Nucleic acids research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Repair of double-strand DNA breaks generated by site-directed endonucleases, like Cas9, is the hallmark of gene editing based on homology-directed repair (HDR). HDR uses an exogenous DNA template to restore the cleaved DNA sequence and can facilitate specific gene corrections as well as insertion of genes or partial complementary DNA (cDNA) sequences. For CRISPR/Cas-directed gene editing, co-administration of the Cas9/single guide RNA (sgRNA) ribonucleoprotein (RNP) complex and a DNA template typically involves two different delivery strategies or different types of vehicles. This requires exquisite timing of delivery and may potentially challenge safety and therapeutic applicability. There is a need therefore for technologies that can ferry complete editing tool kits into cells. Here, we demonstrate the use of lentivirus-derived nanoparticles (LVNPs) to transport both RNP complexes and vector RNA, which upon reverse transcription serves as a repair template for HDR-directed gene editing. Such 'all-in-one' LVNPs support targeted gene insertion with reduced off-target effects relative to nucleofection procedures. We show potent editing in the HBB gene in human erythroid progenitor cells as well as HDR-directed editing in hematopoietic stem and progenitor cells. Our findings mark a first step toward using a single virus-derived vehicle for delivering a full HDR gene editing kit.
