The mouse and human placentas have labyrinthine and villous types of interdigitation between maternal and fetal tissues, respectively
The bulk of the villi consist of connective tissues in which blood vessels are found. Most of the cells in the connective tissue core of the villi are fibroblasts. Macrophages known as Hofbauer cells are also present.
