result of the enhanced aggregation of the macrocyclic molecules in the nanoparticles. The unique packing of the molecules also resulted in a large red-shift of the Q-band absorption to 832 nm, facilitating the in vitro and in vivo photothermal treatment.Posterior capsular opacification (PCO) is the most common complication of cataract surgery. PCO is due to the proliferation, migration, and epithelial-to-mesenchymal transition of the residual lens epithelial cells (LECs) within the lens capsule. As surface topography influences cellular response, we investigated the effect of modulating the dimensions of periodic nano-textured patterns on the surface of an intraocular lens material to regulate lens epithelial cell functions such as cell adhesion, migration, orientation, and proliferation. Patterned poly(HEMA) samples were prepared by a femtosecond laser microfabrication, and the behaviors of human B-3 LECs were observed on groove/ridge patterns with widths varying from 5 to 40 µm. In the presence of ridge and groove patterns, the adherent cells elongated along the direction of the patterns, and f-actin of the cells was spread to a lesser extent on the nano-textured groove surfaces. Both single and collective cell migrations were significantly inhibited in the perpendicular direction of the patterns on the nano-textured micro-patterned samples. We also fabricated the patterns on the curved surface of a commercially available intraocular lens for in vivo evaluation. In vivo results showed that a patterned IOL could help suppress the progression of PCO by inhibiting cell migration from the edge to the center of the IOL. Our reports demonstrate that nano- and microscale topographical patterns on a biomaterial surface can regulate cellular behavior when it is implanted into animals.The liver is the largest internal organ of the body with complex microarchitecture and function that plays critical roles in drug metabolism. Hepatotoxicity and drug-induced liver injury (DILI) caused by various drugs is the main reason for late-stage drug failures. Moreover, liver diseases are among the leading causes of death in the world, with the number of new cases arising each year. Although animal models have been used to understand human drug metabolism and toxicity before clinical trials, tridimensional microphysiological systems, such as liver-on-a-chip (Liver Chip) platforms, could better recapitulate features of human liver physiology and pathophysiology and thus, are often more predictive of human outcome. Liver Chip devices have shown promising results in mimicking in vivo condition by recapitulating the sinusoidal structure of the liver, maintaining high cell viability and cellular phenotypes, and emulating native liver functions. Selleck STAT3-IN-1 Here, we first review the cellular constituents and physiology of the liver and then critically discuss the state-of-the-art chip-based liver models and their applications in drug screening, disease modeling, and regenerative medicine. We finally address the pending issues of existing platforms and touch upon future directions for developing new, advanced on-chip models.Due to its degradability, magnesium holds potential for the application as a base material for local treatment systems. Particularly for the therapy of severe brain-related diseases, local approaches are advantageous. To confirm the suitability of magnesium as a material for neural implants, information on the interaction of brain cells with magnesium is essential. Initial steps of such an evaluation need to include not only cytocompatibility tests but also the analysis of the in vitro material degradation to predict in vivo material performance. Considering the sensitivity and functional importance of neural tissue, an in-depth understanding of the processes involved is of particular relevance. Here, we investigate the influence of four different brain cell types and fibroblasts on magnesium degradation in direct material contact. Our findings indicate cell type as well as cell density-dependent degradation behavior. Metabolic activity (lactate content) appears to be crucial for degradation promotion. Extracellular matrix composition, distribution, and matrix/cell ratios are analyzed to elucidate the cell-material interactions further. Statement of Significance Thanks to their degradability, magnesium (Mg)-based materials could be promising biomaterials for local ion or even drug delivery strategies for the treatment of severe brain-related diseases. To confirm the suitability of Mg as a neural implant material, information on the interaction of brain cells with Mg is essential. Initial steps of such an evaluation need to include cytocompatibility tests and the analysis of the in vitro material degradation to predict in vivo material performance. The present study provides data on the influence of different brain cell types on Mg degradation in direct material contact. Our findings indicate cell type and cell density-dependent degradation behavior, and elucidate the role of cell metabolites and extracellular matrix molecules in the underlying degradation mechanisms.BiCNU (carmustine), etoposide, Ara-C, melphalan (BEAM) and Campath conditioning was developed to reduce the high transplant-related mortality in patients with lymphoma while delivering intensive antilymphoma immunotherapy, as well as to some extent a platform for allogeneic stem cell engraftment. Significant numbers of patients appeared to have persistent recipient-derived hematopoiesis, and therefore we retrospectively analyzed patients with lymphoma undergoing BEAM-Campath conditioned allogeneic stem cell transplantation at our center (2003 to 2017) to characterize the patterns of chimerism and patient outcomes. Chimerism was analyzed with short tandem repeat PCR. Mixed donor-recipient chimerism (MDRC) was defined as 5% to 94.9% donor. Fifty-two patients (n = 30 male), with a median age of 45 years, were identified with histologic diagnoses of Hodgkin lymphoma (n = 13), diffuse large B cell lymphoma (n = 7), low-grade non-Hodgkin lymphoma (n = 16), mantle cell lymphoma (n = 10), and T cell lymphoma (n = 6).
