The present invention discloses the preparation of placenta tissue derived CD106high CD151 +Nestin+ mesenchymal stem cells (MSCs). In a first aspect, the invention relates to a particular method to prepare these cells at industrial scale and the cell population generated thereby. In a second aspect, the invention relates to a cell culture obtained by said particular method, containing placental CD106high CD151 + Nestin+ MSCs expressing the vascular cell adhesion molecule 1 (VCAM-1 ) marker. The present application shows that said placental CD106high CD151 + Nestin+ MSCs are capable of inducing angiogenesis in vitro and in vivo. The herein presented results also show that administering said placental CD106high CD151 + Nestin+ MSCs to individuals suffering from an ischemic disease or from a disorder of the circulatory system results in a detectable improvement of one or more symptoms of said disease or disorder. Therefore, in a third aspect, the invention relates to placental CD 106high CD151 + Nestin+ MSCs for use as a medicament for treating subjects suffering from an ischemic disease, a disorder of the circulatory system, an immune disease, an organ injury or an organ function failure.
