Topical Application of Mesenchymal Stromal Cells Ameliorated Liver Parenchyma Damage After Ischemia-Reperfusion Injury in an Animal Model.

Background: Ischemia-reperfusion injury (IRI) is commonly encountered after liver surgery. This study evaluated the hepatoprotective effects of topically applied adipose-derived mesenchymal stromal cells (ADMSCs) on hepatic IRI in a rat model.

Methods: ADMSCs from transgenic green fluorescent protein Sprague-Dawley rats were topically applied to the liver surface of Sprague-Dawley rats after hepatic IRI and fixed in position by fibrin glue (group A, n = 24).

BACs-on-beads: a new robust and rapid detection method for prenatal diagnosis.

Karyotyping, the gold standard used for diagnosis of chromosomal abnormalities, is being progressively replaced by rapid aneuploidy testing (RAT) techniques such as quantitative fluorescence-PCR, FISH and multiplex ligation-dependent probe amplification for diagnosing the common aneuploidies or chromosomal microarray analysis for comprehensive genome-wide testing. However, due to technical limitations, current RATs are confined to the detection of common aneuploidies 13, 18, 21 and sex chromosomes. To overcome the limitations of RATs, a bacterial artificial chromosomes-on-beads (BoBs™) assay technology has been introduced for the detection of the common aneuploidies as well as specific microdeletion syndromes.
