Effects of Growth Factors on Establishment and Propagation of Embryonic Stem Cells from Very Early Stage IVF Embryos and Their Characterization in Buffalo.

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
BACKGROUND AND
objectivesAlthough ES cells have been derived from very early stage embryos in different species, but, so far ES cell line could be derived from early stage IVF embryos in buffalo. The present experiment was carried out to study the effects of different growth factors on attachment, formation of ES cell colonies, their extent of passaging and relative expression of pluripotency marker in these colonies in buffalo. METHODS AND
resultsFor this, 8~16 cell stages zona free IVF embryos were cultured with different culture condition viz. Control, Media-I: (Control+SCF), Media-II: (Control+SCF+bFGF) and Media-III: (Control+SCF+bFGF+IGF1). A total of 25 number of embryos were cultured in each medium. The efficiency (%) of blastomere attachment, % stem cell colony formation were recorded and number of passaging were evaluated in each culture condition. The results indicated that the efficiency of embryonic blastomere attachment, % stem cell colonies formation and propagation were significantly higher when medium was supplemented with growth factors viz. SCF, bFGF and IGF-1 (Media-III) than when supplemented with either SCF or SCF+bFGF. The expression of pluripotent genes viz Oct4, Nanog, FoxD3 and KLF4 were significantly higher (p<0.005) when medium was supplemented with three growth factors.
conclusionsIt can be concluded that when 8~16 cell stages zona free IVF embryos of buffalo was cultured on feeder,the %of blastomere attachment, % of ES cell colony formation and their further propagation were higher in ES cell medium supplemented with SCF+bFGF+IGF1 which may be due to high expression of pluripotent stem cell markers.
