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

As a result of their pluripotency and potential for unlimited self-renewal, human embryonic stem cells (hESCs) hold tremendous promise in regenerative medicine. An essential prerequisite for the widespread application of hESCs is the establishment of effective and efficient protocols for large-scale cell culture, storage, and distribution. At laboratory scales hESCs are cultured adherent to tissue culture plates; these culture techniques are labor-intensive and do not scale to high cell numbers. In an effort to facilitate larger scale hESC cultivation, we investigated the feasibility of culturing hESCs adherent to microcarriers. We modified the surface of Cytodex 3 microcarriers with either Matrigel or mouse embryonic fibroblasts (MEFs). hESC colonies were effectively expanded in a pluripotent, undifferentiated state on both Matrigel-coated microcarriers and microcarriers seeded with a MEF monolayer. While the hESC expansion rate on MEF-microcarriers was less than that on MEF-plates, the doubling time of hESCs on Matrigel-microcarriers was indistinguishable from that of hESCs expanded on Matrigel-coated tissue culture plates. Standard hESC cryopreservation methodologies are plagued by poor viability and high differentiation rates upon thawing. Here, we demonstrate that cryopreservation of hESCs adherent to microcarriers in cryovials provides a higher recovery of undifferentiated cells than cryopreservation of cells in suspension. Together, these results suggest that microcarrier-based stabilization and culture may facilitate hESC expansion and storage for research and therapeutic applications.
