Directed cell migration
WebMany cells undergo directed cell migration in response to external cues in a process known as chemotaxis. This ability is essential for many single-celled organisms to hunt and mate, the development of multicellular organisms, and the functioning of the immune system. Because of their relative ease of manipulation and their robust chemotactic ... WebFeb 19, 2024 · Dendritic cells (DCs), a class of antigen-presenting cells, are widely present in tissues and apparatuses of the body, and their ability to migrate is key for the initiation of immune activation and tolerogenic immune responses. The importance of DCs migration for their differentiation, phenotypic states, and immunologic functions has attracted …

WebCell migration can be directed by various methods including chemical, adhesive, mechanical, and topographical cues. Electrospinning has emerged as a popular method to control topography and create fibrous scaffolds similar to that found in extracellular matrix. One major hurdle is limited cell infiltration and several studies have explored ... WebCell migration is the directed movement of a single cell or a group of cells in response to chemical and/or mechanical signals. It is a fundamental cellular process that occurs throughout life, starting during embryonic development and continuing until death, and at times it can contribute to pathogenic states in disease.
WebPubMed Central (PMC) WebJul 8, 2014 · We compared cells from wild-type and LPA2 gene-targeted mice, and studied both directed and non-directed migration in vitro, as well as both early and late accumulation of T cells in lymph nodes after adoptive transfer. Here we report that mouse CD4+ T cells differentially express six LPA receptors and that expression of these …
