The embryonic origins of lymphatic vessels: an historical review
Ribatti D, Crivellato E. Br J Haematol. 2010 Jan 13. [Epub ahead of print] PMID: 20067566
- "Summary Work on the lymphatic system began in the 17th century, and by the beginning of the 19th century the anatomy of most of the lymphatic system had been described. One of the most important questions in this field has been the determination of the embryological origin of the lymphatic endothelium. Two theories were proposed. The first suggested that lymphatic endothelium derived by sprouting from venous endothelium, the so-called centrifugal theory. The second, the so-called centripetal theory, suggested that lymphatic endothelium differentiates in situ from primitive mesenchyme, and secondarily acquires connection with the vascular system. More recent evidence has provided support for both hypotheses."

- "The lymphatic system is essential for fluid homeostasis, immune responses, and fat absorption, and is involved in many pathological processes, including tumor metastasis and lymphedema. Despite its importance, progress in understanding the origins and early development of this system has been hampered by lack of defining molecular markers and difficulties in observing lymphatic cells in vivo and performing genetic and experimental manipulation of the lymphatic system. Recent identification of new molecular markers, new genes with important functional roles in lymphatic development, and new experimental models for studying lymphangiogenesis has begun to yield important insights into the emergence and assembly of this important tissue. This review focuses on the mechanisms regulating development of the lymphatic vasculature during embryogenesis."

Abstract
BACKGROUND: The prenatal development of human lymphatic systems has not attracted enough attention by lymphatic researchers in the past. Yet clearly these critical, early events determine the fate and function of the human lymphatic system.
METHODS AND RESULTS: The main focus of these studies was to investigate the embryonic development of human lymphangions including lymphatic valves and muscle cells, to better understand the prenatal formation of basic structural elements of lymph flow. This review in most of its parts is a short summary of the findings. It provides important information necessary for understanding the development and functioning of the human lymphatic system.
CONCLUSIONS: The structural basis of the active lymph transport system--the lymphatic muscle cells and lymphatic valves--which is absolutely necessary for all functions of lymphatic system, is already formed during the first half of the prenatal development in humans. During the second half of this development maturation of this system is already underway. The enlargement of lymphatic muscle cells together with increases in their quantity leads to formation of the multi-layered lymphatic vessel wall, able to develop contractions strong enough to propel lymph downstream of the lymphatic channels against gravity in bipedal humans. The development of the competent valves in lymphatic vessels occurs at the same time creating the ground for effective net, unidirectional lymph flow. The data summarized here represents some of the first systematic studies of the prenatal development of lymphatic muscle cells and valves in humans.
