The yolk sac (YS) represents a promising source of stem cells for research because of the hematopoietic and mesenchymal cell niches that are present in this structure during the development of the embryo. In this study, we report on the isolation and characterization of YS tissue and mesenchymal stem cells (MSCs) derived from bovine YSs. Our results show that the YS is macroscopically located in the exocoelomic cavity in the ventral portion of the embryo and consists of a transparent membrane formed by a central sac-like portion and two ventrally elongated projections.
