Co-cultures of multiple cell types mimic pulmonary cell communication in response to urban PM10.

Non-Viable Lactobacillus Casei Beneficially Modulates Poly I:C Immune Response in Co-Cultures of Human Cells

  Background: Polyinosinic:polycytidylic acid (Poly-IC) has been used as a viral stimulus to mimic in vivo and in vitro infection induced by some viruses. Objective: To determine whether non-viable Lactobacillus casei CRL431 (LcM) can modulate the immune response induced by Poly I:C in co-culture models of peripheral blood mononuclear cells (PBMC) and A549 cells. Methods: T and NK cell activati...

Co-Culture of Mesenchymal Stem Cells with Mature Chondrocytes: Producing Cartilage Construct for Application in Cartilage Regeneration

Background: Cell-based treatment approach using differentiated mesenchymal stem cells (MSCs) and mature chondrocytes has been considered as an advanced treatment for cartilage repair. We investigated the differentiated level of these two cell types that is crucial for their repair capacity for cartilage defect at a co-culture micro mass system. Methods: Passaged-2 MSCs isolated from the mouse b...

Immune response of chickens to four lentogenic strains of Newcastle disease virus propagated in lamb kidney cell cultures

Tissue Engineered Scaffolds in Regenerative Medicine

Stem cells are self-renewing cells that can be differentiated into other cell types. Conventional in vitro models for studying stem cells differentiation are usually preformed in two-dimensional (2D) cultures. The design of three-dimensional (3D) in vitro models which ideally are supposed to mimic the in vivo stem cells microenvironment is potentially useful for inducing stem cell derived tissu...

Alveolar macrophage-epithelial cell interaction following exposure to atmospheric particles induces the release of mediators involved in monocyte mobilization and recruitment

BACKGROUND Studies from our laboratory have shown that human alveolar macrophages (AM) and bronchial epithelial cells (HBEC) exposed to ambient particles (PM10) in vitro increase their production of inflammatory mediators and that supernatants from PM10-exposed cells shorten the transit time of monocytes through the bone marrow and promote their release into the circulation. METHODS The prese...
