The Challenge of Using CB-HSCs As Source for Gene Therapy: Lentiviral Vector Transduction, Phenotypic Characterization and Global Gene Expression Pro…
2015
Abstract Introduction: Genetic modification of autologous hematopoietic stem and progenitor cells (HSPC) is a promising clinical intervention to cure inherited monogenic diseases. Successful gene therapy trials have already been conducted using CD34+ cells from bone marrow and from mobilized peripheral blood. In this regard, cord blood (CB) represents an attractive source of HSCs due to its high concentration of high proliferative HSPC and increased susceptibility to be transduced by lentiviral vectors. Unfortunately, the major disadvantage is the limited number of HSC in the CB collection. Consequently, ex-vivo expansion of CB-HSC is desirable to extend clinical applications. Purposes: To …
Cell and molecular response to IORT treatment
2014
Ionizing radiations (IRs) generated by intraoperative radiotherapy (IORT) treatment activates both pro- and antiproliferative signal pathways producing an imbalance in cell fate decision regulated by several genes and factors involved in cell cycle progression, survival and/or cell death, DNA repair and inflammation. This paper describes the latest advances on cellular and molecular response to IR, highlighting the most relevant research data from cell biology, gene expression profiling and epigenetic studies on different tumor cell types. Understanding the cell molecular strategies to choose between death and survival, after an irradiation-induced damage, opens new avenues for the selectio…
