Abstract
Background Mesenchymal stem cells (MSCs) have shown immense therapeutic potential for various brain diseases. Intrathecal administration of MSCs may enhance their recruitment to lesions in the central nervous system, but any impact on cerebrospinal fluid (CSF) flow remains unclear. Methods Rats with or without middle cerebral artery occlusion (MCAO) received intrathecal injections of 2D cultured MSCs, 3D cultured MSCs or an equal volume of artificial cerebrospinal fluid (ACSF). Ventricle volume was assessed by MRI on Days 2 and 14 post-MCAO surgery. A beam walking test was used to assess fine motor coordination and balance. Aggregation of MSCs was evaluated in CSF and frozen brain tissue. Differential expression of cell adhesion molecules was evaluated by RNA-Seq, flow cytometry and immunofluorescence analyses. The influence of VCAM-1 blockade in mediating the aggregation of 2D MSCs was investigated in vitro by counting cells that passed through a strainer and in vivo by evaluating ventricular dilation. Results MSC expanded in 2D culture formed aggregates in the CSF and caused ventricular enlargement in both MCAO and normal rats. Aggregates were associated with impaired motor function. 2D MSCs expressed higher levels of integrin α4 and VCAM-1 than 3D MSCs. Blockade of VCAM-1 in 2D MSCs reduced their aggregation in vitro and reduced lateral ventricular enlargement after intrathecal infusion. 3D MSCs exhibited lower cell aggregation and reduced cerebral ventricular dilation after intrathecal transplantation Conclusions The aggregation of 2D MSCs, mediated by the interaction of integrin α4 and VCAM-1, is a potential risk for obstruction of CSF flow after intrathecal transplantation.

Abstract
Negatively charged synthetic hydrogels have been known to facilitate various cellular responses including cell adhesion, proliferation, and differentiation; however, the molecular mechanism of hydrogel-dependent control of cell behavior remains unclear. Recently, we reported that negatively charged poly(2-acrylamido-2-methylpropanesulfonic acid) (PAMPS) gel induces chondrogenic differentiation of ATDC5 cells via novel protein reservoir function. In this study, we identified the cell adhesion molecules binding to PAMPS gels that act as mechanoreceptors. First, we performed a pull-down assay by particle gels using cell membrane proteins of ATDC5, and found that multiple membrane proteins bound to the PAMPS gel, whereas the uncharged poly(N,N'-dimethylacrylamide) gel as control did not bind to any membrane proteins. Western blot analysis indicated differential binding of integrin (ITG) isoforms to the PAMPS gel, in which the α4 isoform, but not α5 and αv, efficiently bound to the PAMPS gel. ITG α4 knockdown decreased cell spreading of ATDC5 on PAMPS gels, whereas the enhanced expression increased the behavior. Furthermore, ITG α4 depletion suppressed PAMPS gel-induced expression of bone morphogenic protein (BMP) 4 contributing to chondrogenic differentiation, in concordance with the reduction of ERK activation. These results demonstrated that membrane protein binding to PAMPS gels occurred in a charge-dependent manner, and that ITG α4 plays a crucial role in cell spreading on PAMPS gels and acts as a mechanoreceptor triggering cellular signaling leads to chondrogenic differentiation.

Abstract
Blockade of α4 integrin by antibodies could be an appropriate treatment strategy in multiple sclerosis and Crohn's disease. Considering disadvantages of antibodies, other elements (e.g. aptamers) have been proposed for antibodies replacement. Isolation of aptamers through cell-SELEX (systematic evolution of ligands by exponential enrichment) method requires positive and negative expressing α4 integrin cell lines. For a better isolation, we intended to construct a negative cell line lacking of specific ligand binding site of α4 integrin. Escherichia coli strain top 10 was used for truncated integrin subunit α4 (TITGA-4) expression vector. Human embryonic kidney (HEK)-293T cell was transfected with linearized TITGA-4 plasmid and subsequently screened for stable truncated TITGA-4 expressing cells. Chromosomal DNA of truncated TITGA-4-transfected cells was extracted and the presence of truncated TITGA-4 gene in HEK-293T genome was confirmed by polymerase chain reaction (PCR). The expression level of truncated TITGA-4 on HEK-293T cells was also analysed by real-time PCR and flow cytometry. Real-time PCR and flow cytometric analysis showed significant difference of truncated TITGA-4 expression between untransfected HEK-293T cells compared to transfected cells. The results suggest that we have successfully constructed the truncated integrin α4 expressing HEK-293T cell, which will facilitate further research into the production of antibody, nanobody, and aptamer against α4 integrin.

Abstract
PURPOSE Integrins are heterodimeric membrane proteins, which are exposed to post translational modifications in eukaryotic cells in contrast to prokaryotic cells. These modifications provide advantages for production of proper nanobody, mono and polyclonal antibody against this surface protein and also in aptamer selection process. Since the majority of diagnostic and therapeutic antibodies, target the surface epitopes, eukaryotic membrane proteins provide an appropriate model for further investigation on therapeutic agents. METHODS Escherichia coli strain top 10, was used as host for ITGA-4 expression vector encoding the human integrin α4. The plasmid was extracted and consequently, ITGA-4 vector was digested to make a linear plasmid. Human Embryonic Kidney-293 (HEK-293) cell transfected with linear plasmid and subsequently screened for stable ITGA-4 expressing Cells. Three separated clones were isolated twenty one days after transfection. Chromosomal DNA was extracted from ITGA-4-transfected cells. The presence of ITGA-4 gene in HEK-293 genome was confirmed by PCR. The expression level of ITGA-4 on HEK-293 cells was also analyzed by Flow cytometry. RESULTS Flow cytometric analysis showed that HEK-293 cells have no expression of integrin α4 on their surface while 95% of transfected HEK-293 cells with ITGA4, expressed different levels of integrin α4 on their surfaces which correlates well with genomic DNA PCR amplification results. CONCLUSION The results suggest that we have successfully constructed the integrin α4 expressing HEK293 cell, which will facilitate further research into the production of antibody, nanobody and aptamer against α4 integrin.
