1 · What the graph read from it

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.

2 · The registry

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

Efficient and controlled gene delivery from biodegradable materials can be employed to stimulate cellular processes that lead to tissue regeneration. In this report, a substrate-mediated approach was developed to deliver DNA from hyaluronic acid-collagen hydrogels. The hydrogels were formed by crosslinking HA with poly(ethylene glycol) diglycidyl ether. Poly(ethylene imine)(PEI)/DNA complexes were immobilized to the substrate using either biotin/neutravidin or non-specific adsorption. Complexes were formed in the presence or absence of salt to regulate complex size, and resulted in complexes with z-average diameters of 1221.7 +/- 152.3 and 139.4 +/- 1.3 nm, respectively. During 48-h incubation in PBS or hyaluronidase, DNA was released slowly from the hydrogel substrate (<30% of immobilized DNA), which was enhanced by incubation with conditioned media (approximately 50% of immobilized DNA). Transgene expression mediated by immobilized, large diameter complexes was 3 to 7-fold greater than for small diameter complexes. However, the percentage of cells expressing the transgene was greater for small diameter complexes (48.7%) than for large diameter complexes (22.3%). Spatially controlled gene transfer was achieved by topographically patterning the hydrogel to pattern cell adhesion. Biomaterial-based gene delivery can be applicable to numerous tissue engineering applications, or as a tool to examine tissue formation.
