Engineered models of the lymphatic vascular system: Past, present, and future
The lymphatic vascular system is crucial for optimizing body fluid level, regulating immune function, and transporting lipid. Relative to the experimental models to investigate blood vasculature, there are significantly fewer tools to explore lymphatics. Although in vivo studies have contributed to major discoveries in the field, finding and characterizing lymphatic specific markers has opened the door to isolating lymphatic vessels and cells for building ex vivo and in vitro platforms. These preparations have enabled the study and analysis of lymphatic vasculature in various physiological and pathophysiological conditions leading to a better understanding of cellular expressions and signaling. In this review, a broad range of ex vivo and in vitro engineered models are highlighted and categorized based on the major lymphatic function they model including contractile function, inflammation, drainage and immune regulation, lymphangiogenesis, and tumor-lymphatic interactions. Then, the novel 3D engineered tissues are introduced consisting of acellularized scaffolds and hydrogels to form vessels and cellular structures close to in vivo morphology. This paper also compares traditional in vitro methods with recent technologies and elaborates on the inherent advantages and limitations of each preparation by critically discussing simplest to most complex tissue-cellular structures. It concludes with an outlook of the lymphatic vasculature models and the possible future direction of contemporary tools, such as organ-on-chips.
期刊介绍:
The journal features original contributions that are the result of investigations contributing significant new information relating to the vascular and lymphatic microcirculation addressed at the intact animal, organ, cellular, or molecular level. Papers describe applications of the methods of physiology, biophysics, bioengineering, genetics, cell biology, biochemistry, and molecular biology to problems in microcirculation.
Microcirculation also publishes state-of-the-art reviews that address frontier areas or new advances in technology in the fields of microcirculatory disease and function. Specific areas of interest include: Angiogenesis, growth and remodeling; Transport and exchange of gasses and solutes; Rheology and biorheology; Endothelial cell biology and metabolism; Interactions between endothelium, smooth muscle, parenchymal cells, leukocytes and platelets; Regulation of vasomotor tone; and Microvascular structures, imaging and morphometry. Papers also describe innovations in experimental techniques and instrumentation for studying all aspects of microcirculatory structure and function.
