Cells
In 2005, Mickie Centrone was diagnosed with Hodgkin's Lymphoma. In her manuscript, she puts into words her experiences with both death and life.

Car-Modified T Cells Capable of Distinguishing Normal Cells From Malignant Cells
<p>T cells can be redirected to target tumor-associated antigen (TAA) by genetic modification to express a chimeric antigen receptor (CAR), which fuses the specificity derived from an antibody to T-cell activation domains to result in lysis of TAA-expressing cells. Due to the potential for …

Neurogenesis from Neural Stem Cells, Ependymal Cells and Fibroblasts
… Stroke leads to loss of neurons and also other cells in the brain due to lack of blood supply. Currently no therapies are available to treat stroke-related disability. It has been shown that stroke leads to increased neurogenesis, birth of new neurons, within the brain. This increased …

Directed differentiation of endodermal cells from mouse embryonic stem cells
Pluripotent embryonic stem cells hold a great promise as an unlimited source of tissue for treatment of chronic diseases such as Type 1 diabetes and chronic liver disease. Various attempts have been made to produce cells that can serve as precursors for pancreas and liver. By using …

Series interconnected solar cells and solar cells with integrated bypass diode
… solar cell modules consists of small area cells connected in series to give desired output voltages. As large area substrates become available, e.g. continuously grown ribbons, the current output of a solar cell made from a large substrate becomes excessively large so that the substrate …

Investigating interplay between human regulatory T cells and oligodendrocyte lineage cells
… initially restored by oligodendrocyte progenitor cells (OPCs) that migrate to, and proliferate in the site of injury, differentiate into mature oligodendrocytes (OLs) and generate new myelin sheaths, a process termed remyelination. The signals that influence this process in the central nervous …

The interactions of tolerogenic dendritic cells, induced regulatory T cells and antigen-specific IgG1-secreting plasma cells in asthma
… IL-10-differentiated dendritic cells (DC) (DC10) leads to progressive and long-lasting full-spectrum asthma tolerance. However, little has been done in investigating a role for antigen-specific B cells in DC10-induced tolerance. In this study, we characterized the surface markers …

Dendritic Cells Suppress Pathogen-Induced Inflammasome Activation to Prime Naïve T Cells
… whether inflammasome activation in dendritic cells (DCs) is critical for T cell priming is not clear. Here, we find that lymphoid organ resident conventional DCs (cDCs) actively suppress inflammasome activation to prevent pyroptotic cell death. This protection from inflammasome-induced cell …

Potential Rest Targets In Neural Stem Cells and Glioblastoma-Derived Stem Cells
… by self-renewing glioblastoma-derived stem cells (GSCs). At the current time, the mechanisms that regulate self-renewal and other oncogenic properties of GSCs remain unknown. Recently, we found transcriptional repressor REST maintains self-renewal in neural stem cells (NSCs) and in GSCs. …

Regulatory Mechanisms Underlying the Differentiation of Mesenchymal Stem Cells to Endothelial Cells
… |Bone marrow (BM)-derived mesenchymal stem cells (MSCs) can differentiate into endothelial cells (ECs) in the presence of vascular endothelial growth factor (VEGF) — 165 in vitro. Translational models have demonstrated that differentiated BM-derived MSCs can be transplanted into the site of …

Enhancing materials for fuel cells and organic solar cells through molecular design
… research in improving efficiencies of solar cells and fuel cells have grown rapidly over the last few decades. One prominent strategy to improving the efficiencies in these devices focuses on engineering materials with customized molecular structure for enhancements in specific properties. …

Chemotaxis of Sperm Cells
Sperm cells are guided to the egg by chemoattractants in many species. Sperm cells are propelled in a liquid by the regular beat of their flagellum. In the presence of a concentration gradient of a chemoattractant, they can steer upwards the concentration gradient, a process called chemotaxis. Eggs …

Cells, surfaces and adhesion
… the basis for synthetic cartilage. Cartilage cells (chondrocytes) plated onto the surface of the porous IPN materials maintain a rounded shape and hence phenotypic function when a critical pore size and density is achieved. In this way, a prospective implant, made porous at the perpendicular …

Cells and force transduction
This thesis studies mechanism involved in propagating force generated at cadherin complexes. The first part of this thesis demonstrates that mechanotransduction at classical cadherin complexes is not only ligand-dependent but also dependent on the respective receptor tyrosine kinase (RTK) binding …

Semi-finished modular cells
This thesis subject is a pre-fabricated element (cell): a system that employs natural, light, and economic materials to produce a near-finished portion of a building. The intent is to introduce sustainable design into construction industry through prefabrication. The cell has been envisioned both …

Dye sensitized solar cells: optimization of Grätzel solar cells towards plasmonic enhanced photovoltaics
… method of producing energy is using solar cells to convert sunlight into electrical energy through photovoltaic processes. Currently, the most widely commercialized solar cell is based on a single p-n junction with silicon. Silicon solar cells are able to obtain high efficiencies but the …
