Kinship of conditionally immortalized cells derived from fetal bone to human bone-derived mesenchymal stroma cells.
Article in Scientific reports, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 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
The human fetal osteoblast cell line (hFOB 1.19) has been proposed as an accessible experimental model for study of osteoblast biology relating to drug development and biomaterial engineering. For their multilineage differentiation potential, hFOB has been compared to human mesenchymal progenitor cells and used to investigate bone-metabolism in vitro. Hereby, we studied whether and to what extent the conditionally immortalized cell line hFOB 1.19 can serve as a surrogate model for bone-marrow derived mesenchymal stromal cells (bmMSC). hFOB indeed exhibit specific characteristics reminiscent of bmMSC, as colony formation, migration capacity and the propensity to grow as multicellular aggregates. After prolonged culture, in contrast to the expected effect of immortalization, hFOB acquired a delayed growth rate. In close resemblance to bmMSC at increasing passages, also hFOB showed morphological abnormalities, enlargement and finally reduced proliferation rates together with enhanced expression of the cell cycle inhibitors p21 and p16. hFOB not only have the ability to undergo multilineage differentiation but portray several important aspects of human bone marrow mesenchymal stromal cells. Superior to primary MSC and osteoblasts, hFOB enabled the generation of continuous cell lines. These provide an advanced basis for investigating age-related dysfunctions of MSCs in an in vitro 3D-stem cell microenvironment.
