Mesoangioblast
（重定向自Mesoangioblasts）
A mesoangioblast is a mesenchymal-like cell, associated with the walls of the large vessels. Mesoangioblasts exhibit many similarities to pericytes found in the small vessels. Mesoangioblasts are relatively undifferentiated cells with the potential to progress down the endothelial or mesodermal lineages. Mesoangioblasts express the endothelial marker Flk-1, but not haematopoietic markers such as Tal-1.
