Abstract
Human immunodeficiency virus (HIV) still poses enigmatic threats to human life. This virus has mastered in bypassing anti retroviral therapy leading to patients’ death. Circulating viruses are phenomenal for the disease outcome. This hypothesis proposes a therapeutic strategy utilizing receptor-integrated hematopoietic, erythroid and red blood cells. Here, HIV specific receptors trap circulating viruses that enter erythrocyte cytoplasm and form inactive integration complex. This model depicts easy, effective removal of circulating HIV without any adverse effect.

Abstract
Stem cell-based gene therapy has been considered in the treatment of many degenerative diseases. Gene-modified stem cells should maintain its reproductive activity without losing stem cell properties, including genetic phenotype and differentiation potential. In the study, a novel poly (amidoamine) with pendant aminobutyl group (PAA-BA) designed by our group was used in the transfection of bone marrow mesenchymal stromal cells (BMSCs) and the cellular properties post-transfection were evaluated, including DNA content, colony forming capacity, genetic phenotype, and multi-directional differentiation. Two classical non-viral gene delivery vectors, polyethylenimine (PEI) and Lipofectamine 2000 (LP2000) were also used. Compared to non-transfected group, PAA-BA showed minor decreased DNA content but maintained BMSCs' phenotype, reproductive activity and multi-differentiation potential (osteogenic, chondrogenic, adipogenic, and neurogenic differentiation). Both PAA-BA and PEI transfected BMSCs demonstrated improved osteogenic differentiation ability at late stage but suppressed adipogenic as well as mature neural differentiation in vitro. LP2000 and PEI transfected BMSCs displayed significantly lower DNA content and reproductive activity. These findings suggest that PAA-BA is one of safe gene delivery vectors in BMSCs transfection and plays a role in stem cell's osteogenic and neurogenic differentiation. This study proposes the potential application of PAA-BA in BMSCs based gene therapy, in particular bone and nerve relative diseases. © 2017 Wiley Periodicals, Inc.

Abstract
Currently, sustained in vivo delivery of active bone morphogenetic protein-2 (BMP-2) protein to responsive target cells, such as bone marrow-derived mesenchymal stem cells (BMSCs), remains challenging. Ex vivo gene transfer method, while efficient, requires additional operation for cell culture and therefore, is not compatible with point-of-care treatment. In this study, two lentiviral gene constructs - (1) Lv-BMP/GFP, containing human BMP-2 and green fluorescent protein (GFP) gene (BMP group); or (2) Lv-GFP, containing GFP gene (GFP group) - were incorporated with human BMSCs into a solution of photocrosslinkable gelatin, which was then subjected to visible light-based projection stereolithographic printing to form a scaffold with desired architectures. Upon in vitro culture, compared to the GFP group, cells from BMP group showed >1,000-fold higher BMP-2 release, and the majority of them stained intensely for alkaline phosphatase activity. Real-time RT-PCR also showed dramatically increased expression of osteogenesis marker genes only in the BMP group. 3.5 months post-implantation into SCID mice, the micro-computed tomography imaging showed detectable mineralized areas only in the BMP group, which was restricted within the scaffolds. Alizarin red staining and immunohistochemistry of GFP and osteocalcin further indicated that the grafted hBMSCs, not host cells, contributed primarily to the newly formed bone.

Abstract
Despite the decline in U.S. cancer incidence and mortality rates, cancer remains the number one cause of death for people under the age of 85 and one in four people in the U.S. will die of cancer, mainly because of metastasis. Recently, interest in mesenchymal stem cell (MSC) tumor-homing has led to inquires into: (a) why MSCs home to tumors, (b) what the inherent protumor and antitumor consequences are, and (c) how to best capitalize on MSC tumor-homing for cell-based diagnostics and therapy. Here, these questions are reviewed and method for addressing them using animal models and tracking methodologies (or, synonymously, detection methodologies) are discussed. First, MSCs in a regenerative and tumor-homing context are reviewed, followed by MSC delivery and genetic labeling methods for tissue model systems. Finally, the use of the nonoptical methods, magnetic resonance imaging, positron emission tomography, and single photon emission computed tomography, along with optical methods, fluorescence imaging and bioluminescent imaging, are reviewed related to tracking MSCs within disease model settings. The benefits and drawbacks of each detection method in animal models is reviewed along with the utility of each for therapeutic use.

Abstract
Adeno-associated virus 2 (AAV2) vectors transduce fibroblasts and mesenchymal stem cells (MSCs) inefficiently, which limits their potential widespread applicability in combinatorial gene and cell therapy. We have reported that AAV2 vectors fail to traffic efficiently to the nucleus in murine fibroblasts. We have also reported that site-directed mutagenesis of surface-exposed tyrosine residues on viral capsids leads to improved intracellular trafficking of the mutant vectors, and the transduction efficiency of the single tyrosine-mutant vectors is ∼10-fold higher in human cells. In the current studies, we evaluated the transduction efficiency of single as well as multiple tyrosine-mutant AAV2 vectors in murine fibroblasts. Our results indicate that the Y444F mutant vectors transduce these cells most efficiently among the seven single-mutant vectors, with >30-fold increase in transgene expression compared with the wild-type vectors. When the Y444F mutation is combined with additional mutations (Y500F and Y730F), the transduction efficiency of the triple-mutant vectors is increased by ∼130-fold and the viral intracellular trafficking is also significant improved. Similarly, the triple-mutant vectors are capable of transducing up to 80-90% of bone marrow-derived primary murine as well as human MSCs. Thus, high-efficiency transduction of fibroblasts with reprogramming genes to generate induced pluripotent stem cells, and the MSCs for delivering therapeutic genes, should now be feasible with the tyrosine-mutant AAV vectors.
