摘要: Lymphatic development in mice is initiated the trunk at embryonic day (E) 9.5. This study aimed to examine origin of craniofacial lymphatic endothelial cells (LECs) and developmental process vessels mouse region. Serial sections from ICR embryos E9.5–E14.5 were immunolabeled with LEC venous cell (VEC) markers. These markers included prospero homeobox protein 1 (Prox1), vascular growth factor receptor 3 (Vegfr3), vessel hyaluronan (Lyve1), C-C motif chemokine 2 (Ccl21) for LEC, COUP transcription (CoupTF2) endomucin (Emcn) VEC. LECs monitored as an index Prox1/Vegfr3 double-positive using three-dimensional analysis because express Prox1 Vegfr3 ab initio during development. appeared VECs lateral walls cardinal veins (CVs) E9.5. dichotomized into populations that formed lymph sacs close CVs scattered surrounding CVs. The cellular streams extended mandibular arches E10.5 - E11.5. In arches, individual aggregated, tubular E11.5–E14.5. Expression marker proteins Lyve1 Ccl21 changed Collectively, these findings suggest originate migrate arches. Additionally, we found are according morphogenesis
