Three-dimensional (3D) culture systems are critical to investigate cell physiology and to engineer tissue grafts. In this study, we describe a simple yet innovative bioreactor-based approach to seed, expand, and differentiate bone marrow stromal cells (BMSCs) directly in a 3D environment, bypassing the conventional process of monolayer (two-dimensional(More)
Clinical observations in patients undergoing bone marrow transplantation implicate the involvement of CD8(+) cells in promoting the stem-cell engraftment process. These findings are supported by mouse transplant studies, which attributed the engraftment-facilitating function to subpopulations of murine CD8(+) cells, but the analogous cells in humans have(More)
Hev b 6.01 is a major allergen of natural rubber latex with sensitization of 70-86% of latex glove-allergic subjects. Recently, we mapped the immunodominant T cell sites of Hev b 6.01 to the highly IgE-reactive hevein (Hev b 6.02) domain. Hev b 6.01 contains 14 cysteine residues with multiple disulphide bridges stabilizing tertiary conformation. With the(More)
Hematopoietic stem cell transplantation (HSCT) requires conditioning treatments such as irradiation, which leads to a severely delayed recovery of T cell immunity and constitutes a major complication of this therapy. Currently, our understanding of the mechanisms regulating thymic recovery is limited. It is known that a subpopulation of bone marrow(More)
Allergen-specific immunotherapy is a clinically proven effective treatment for many allergic diseases, including asthma; however, it is not currently available for latex allergy because of the high risk of anaphylaxis. There is, therefore, a crucial need for an animal model of latex allergy in which to develop effective immunotherapy. Previous mouse models(More)
T-cell production throughout life depends on efficient colonization and intrathymic expansion of BM-derived hematopoietic precursors. After irradiation-induced thymic damage, thymic recovery is facilitated by Flt3 ligand (FL), expressed by perivascular fibroblasts surrounding the thymic entry site of Flt3 receptor-positive progenitor cells. Whether(More)
The low molecular weight compound VAF347, and its pro-drug version VAG539, interact with the transcription factor aryl hydrocarbon receptor (AhR) on monocytes to mediate its anti-inflammatory activity in vitro and in vivo. AhR is a crucial factor for IL-22 production, which regulates skin and gut homeostasis. Here we investigated whether VAF347 might(More)
