Stone and Stainier show that lymphatic endothelial cell fate is imprinted much earlier as cells transition through the paraxial mesoderm. To determine their contribution to the postnatal and adult lymphatic endothelium, we lineage .In geometric optics, the paraxial approximation is a small-angle approximation used in Gaussian optics and ray tracing of light through an optical system. In this process, key developmental processes, including initiation of the segmentation clock, . Paraxial bedeutet neben einer Körperachse bzw.A striking paradigm for this diversification can be observed in the endothelium, which differentiates from mesoderm to form arterial, venous, lymphatic, and organ-specific .Vertebrates form their skeletal tissues from three distinct origins (the neural crest, paraxial mesoderm, and lateral plate mesoderm) through two distinct modes of ossification (intramembranous and endochondral ossification). To determine their contribution to the postnatal and adult lymphatic endothelium, we lineage traced PXMDCs and analyzed whole-mount tissues and sections.

Paraxial Mesoderm

A paraxial ray is a ray which makes a small angle to the optical axis of the system, and lies close to the axis throughout the system. Stichworte: Lageangabe, Lagebezeichnung.Paraxial mesoderm is responsible for the formation of the vertebrae as well as the dermis of the skin, striated skeletal muscle, muscles of the head and connective tissue [4]. Somites give rise to three major divisions: the dermatome, the myotome, and the sclerotome. As the primitive node and the primitive streak regress toward the caudal end of the embryo, they leave behind the notochord and the induced neural plate.In this definition, the somite is a homologously-paired structure in an animal body plan, such as is visible in annelids and arthropods.Paraxial mesoderm is segmented into sequentially ordered blocks of cells referred to as somites, which differentiate into the sclerotome and dermomyotome, giving rise to axial . The mesoderm forms at the same time as the other two germ layers, the ectoderm and endoderm.The second region is the paraxial mesoderm (or somitic dorsal mesoderm). μέσος [mésos] „mittig“, „mittlerer“ und to derma „Haut“) ist das mittlere Keimblatt des Embryoblasten.The sequential formation of somites along the anterior-posterior axis is under control of multiple signaling gradients involving the Wnt, FGF, and retinoic acid (RA) pathways.Directed specification and prospective isolation of chondrogenic paraxial mesoderm progeny from human pluripotent stem (PS) cells have not yet been achieved. The cells in this region will form somites, blocks of mesodermal cells on both sides of the neural tube that will produce many of the .This then leads to the formation of the paraxial mesoderm, the intermediate mesoderm, and the lateral plate mesoderm (Fig. Here we report the successful .
