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

Current acellular adipose tissue engineering focuses primarily on structural regeneration, whereas functional metabolic recovery remains a major challenge. Extracellular vesicles (EV) derived from adipose tissue (AT-EV) have recently emerged as potent mediators of tissue regeneration, and cold stimulation has been reported to enhance the metabolic reprogramming of AT-EV. We have previously reported that fat grafts from cold-stimulated mice exhibited enhanced survival and adipose regeneration. Yet whether cold-induced AT-EV contribute to in vivo metabolic adipose regeneration remains unclear. Moreover, the cold stimulation temperatures used in traditional mouse models are often intolerable for humans. To address this, we developed a short-term intermittent mild cold exposure (STIMCE) protocol to metabolically activate murine adipose tissue for EV isolation (STIMCE-EV). Following only 3 or 7 days of STIMCE treatment, adipose tissue exhibited increased EV secretion and enrichment of mitochondrial components. Moreover, STIMCE-EV were efficiently incorporated into human acellular adipose matrix (AAM) hydrogel and exhibited controlled release in vitro. Injectable AAM@STIMCE-EV hydrogel transplantation in nude mice showed improved adipogenesis and volume retention in situ after 2 months. Importantly, the AAM@STIMCE-EV grafts improved cold adaptation and enhanced the thermogenic function of the host mice. Mechanistically, mmu-miR-296-3p was identified as a key regulatory factor within STIMCE-EV. Exogenous mmu-miR-296-3p supplementation significantly improved the adipogenic regeneration of AAM. Overall, this study presents a metabolically activated, cell-free adipose regeneration strategy that combines STIMCE-EV with AAM scaffolds. This minimally invasive and injectable system enables functional adipose tissue regeneration with systemic thermogenic metabolic activity, providing a promising translational solution for soft tissue reconstruction.
