Multi-Parameter Analysis of Biobanked Human Bone Marrow Stromal Cells Shows Little Influence for Donor Age and Mild Comorbidities on Phenotypic and Functional Properties.

Heterogeneous populations of human bone marrow-derived stromal cells (BMSC) are among the most frequently tested cellular therapeutics for treating degenerative and immune disorders, which occur predominantly in the aging population. Currently, it is unclear whether advanced donor age and commonly associated comorbidities affect the properties of -expanded BMSCs. Thus, we stratified cells from adult and elderly donors from our biobank ( = 10 and = 13, mean age 38 and 72 years, respectively) and compared their phenotypic and functional performance, using multiple assays typically employed as minimal criteria for defining multipotent mesenchymal stromal cells (MSCs).

Association of the Nicotinic Receptor α7 Subunit Gene (CHRNA7) with Schizophrenia and Visual Backward Masking.

The nicotinic system is involved in the pathophysiology of schizophrenia. However, very little is known about its genetic basis and how it relates to clinical symptoms and potentially pharmacological intervention. Here, we investigated five single nucleotide polymorphisms (SNPs) [rs3826029] [rs2337506] [rs982574] [rs904952] [rs2337980] of the cholinergic nicotinic receptor gene, alpha 7 subunit (CHRNA7) and their association to schizophrenia.

A T-cell receptor gamma polymerase chain reaction assay using capillary electrophoresis for the diagnosis of cutaneous T-cell lymphomas.

Detection of clonal T-cell receptor gamma rearrangements by polymerase chain reaction (TCRgamma PCR) followed by high-resolution electrophoresis has now become a valuable tool in the diagnosis of cutaneous T-cell lymphoma (CTCL). The identification of clonal TCRgamma PCR products by fluorescent fragment analysis (FFA) on a capillary DNA sequencer is described here and compared with an established hetero-duplex temperature gradient gel electrophoresis (HD-TGGE). Of 55 CTCL derived lesional skin samples, clonality was obtained in 46 samples by FFA (83.
