Influence of supramammary lymph node extract on in vitro cell proliferation.
Article in Cell proliferation, 2008. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
objectivesExperiments were conducted to evaluate whether or not bovine supramammary lymph node extract (LNE) could support cell proliferation when it was substituted for bovine growth serum (BGS) in cell culture media. MATERIALS AND
methodsTwo different preparations of LNE were tested. The first yielded protein concentration of 3 mg/mL and the second contained 27 mg/mL protein. Three cell lines (MDA-MB-435, MAC-T and 1C6) were used in serum starvation assays to evaluate LNE. Cell proliferation assays were used to determine growth stimulation in the presence of LNE, and short-term or rapid adaptation cultures were evaluated for LNE effects on cell survival.
resultsHeat-inactivated preparation 1 supported cell proliferation as well as or better (12-39%) than BGS following 2 days of serum starvation in culture. The second lymph node preparation provided a stimulatory effect (263-702% greater than BGS across all cell lines) following serum starvation at 2.7 and 5.4 mg/mL protein supplementation. A gradual adaptation process with lymph node supplementation into media maintained cell population growth on a short-term basis. However, once cells were trypsinized or scraped and re-seeded into 2.7 mg/mL LNE protein containing media, cells were unable to re-adhere, leaving them detached, and eventually appearing to be dead.
conclusionsSubstitution of BGS with LNE protein dramatically stimulated cells to proliferate, but did not allow for rapid cell population growth adaptation in vitro.
