[Constitutive expression of the potential stem cell marker CD44 in permanent HNSCC cell lines].
Article in HNO, 2008. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
backgroundDespite significant advances and the use of new diagnosic and therapy methods to treat head and neck squamous cell carcinoma (HNSCC), prognosis has improved only marginally in the last decades. Thus, there is an enormous need for novel immunotherapeutic approaches. It is becoming more and more obvious that stem cells play an important role in tumor development and progression. The identity of these cells and the underlying cellular and molecular mechanisms remain mostly unknown in HNSCC. MATERIAL AND
methodsSolid tumors as well as cells from the peripheral blood of patients with HNSCC were analyzed by flow cytometry concerning the expression of different putative stem cell marker proteins.
resultsDistinct populations of CD44-positive (CD44+), lin-negative (lin-) potential stem cells could be identified in solid tumors of HNSCC patients with strong individual variations. Surprisingly, the potential stem cell marker CD44 was found to be constitutively expressed on the surface of all permanent HNSCC cell lines analyzed.
conclusionThese data strongly suggest that CD44+ tumor stem cells may play a key role in establishment of permanent HNSCC cell lines, selecting especially robust cell entities that in real life might drive progression and metastasis of HNSCC. Individual analysis of tumor stem cell markers will be an important tool for innovative therapies and prognosis of patients with HNSCC. Additional stem cell markers will be investigated concerning their expression and cellular function.
