Biomarkers for monitoring pre-analytical quality variation of mRNA in blood samples.

There is an increasing need for proper quality control tools in the pre-analytical phase of the molecular diagnostic workflow. The aim of the present study was to identify biomarkers for monitoring pre-analytical mRNA quality variations in two different types of blood collection tubes, K2EDTA (EDTA) tubes and PAXgene Blood RNA Tubes (PAXgene tubes). These tubes are extensively used both in the diagnostic setting as well as for research biobank samples.

Prediction of mild cognitive impairment that evolves into Alzheimer's disease dementia within two years using a gene expression signature in blood: a pilot study.

Background: The focus on Alzheimer's disease (AD) is shifting from dementia to the prodromal stage of the disorder, to a large extent due to increasing efforts in trying to develop disease modifying treatment for the disorder. For development of disease-modifying drugs, a reliable and accurate test for identification of mild cognitive impairment (MCI) due to AD is essential.

Objective: In the present study, MCI progressing to AD will be predicted using blood-based gene expression.

Self-monitoring of blood glucose improved glycaemic control and 10-year coronary heart disease risk profile of type 2 diabetic patients.

Background: The debate over the overall benefits of self-monitoring of blood glucose in type 2 diabetes patients is still continuing. We aimed to assess the difference in glycaemic control and coronary heart disease (CHD) risk levels of experimental type 2 diabetes patients provided with facilities for self-monitoring blood glucose and their counterparts without such facilities.

Methods: Sixty-one patients who had no prior experience in using glucometers were studied as intervention (n = 30) and control (n = 31) groups.

Transiently redirected T cells for adoptive transfer.

Background Aims: T cells can be redirected to reject cancer by retroviral transduction with a chimeric antigen receptor (CAR) or by administration of a bispecific T cell engager (BiTE). We demonstrate that transfection of T cells with messenger (m) RNA coding for CAR is an alternative strategy.

Methods: We describe the pre-clinical evaluation of a method based on transient modification of expanded T cells with a CD19 CAR directed against B-cell malignancies.

Extensive adipogenic and osteogenic differentiation of patterned human mesenchymal stem cells in a microfluidic device.

Microtechnology offers great prospects for cellular research by enabling controlled experimental conditions that cannot be achieved by traditional methods. This study demonstrates the use of a microfluidic platform for long-term cultivation (3 weeks) of human mesenchymal stem-like cells (MSCs), a cell population of high interest for tissue engineering. The typical high motility of the MSCs required a strategy for preventing cells from inhabiting the feeding channels and thus interfere with a steady perfusion of medium to the cell cultivation chamber.
