Sugar-Assisted Cryopreservation of Stem Cell-Laden Gellan Gum-Collagen Interpenetrating Network Hydrogels.
Article in Biomacromolecules, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Tissue engineering involves the transplantation of stem cell-laden hydrogels as synthetic constructs to replace damaged tissues. However, their time-consuming fabrication procedures are hurdles to widespread application in clinics. Fortunately, similar to cell banking, synthetic tissues could be cryopreserved for subsequent central distribution. Here, we report the use of trehalose and gellan gum as biomacromolecules to form a cryopreservable yet directly implantable hydrogel system for adipose-derived stem cell (ADSC) delivery. Through a modified cell encapsulation method and a preincubation step, adequate cryoprotection was afforded at 0.75 M trehalose to the encapsulated ADSCs. At this concentration, trehalose demonstrated lower propensity to induce apoptosis than 10% DMSO, the current gold standard cryoprotectant. Moreover, when cultured along with trehalose after thawing, the encapsulated ADSCs retained their stem cell-like phenotype and osteogenic differentiation capacity. Taken together, this study demonstrates the feasibility of an "off-the-shelf" biomacromolecule-based synthetic tissue to be applied in widespread tissue engineering applications.
