Development of a 3D coculture system to study adipocyte and lymph node cell interactions

We have developed a long term 3-dimensional coculture system with adipocytes and lymph node cells for the purpose of investigating interactions between these cells in vitro. Present experimental work with the culture system is aimed at introducing lymph node cells, in proportions similar to those found in intact lymph nodes, among differentiated adipocytes and observing interactions and the establishment of a spatial relationship between them. Co-cultures will be used to investigate the lymph node adipocyte interactions following immune stimulation (lipopolysaccharide treatment) measuring production of inflammatory mediators (cytokines) and lipolytic activity.
