Perinatal and Wharton's jelly-derived mesenchymal stem cells in cartilage regenerative medicine and tissue engineering strategies
2011
Stem cells can be found in embryonic and extraembryonic tissues as well as in adult organs. In particular, research in the last few years has delineated the key features of perinatal stem cells derived from fetus-associated tissues. These cells show multiple differentiation potential, can be easily expanded ex vivo, and raise no ethical concerns as regards their use. Several reports indicate that cells isolated from Wharton's jelly (WJ), the main component of umbilical cord extracellular matrix, are multipotent stem cells that express markers shared by other mesenchymal stem cells (MSC) and give rise to different mature cell types belonging to all three germ layers. Moreover, WJ-MSC display…

Mesenchymal stem cells (MSC) are considered promising tools in regenerative medicine applications. Even if they are already applied clinically, their extended characterization is being increasingly viewed as a needed feature, in order to avoid contrasting results when translating “in vitro” experiments to “in vivo” approaches. We recently demonstrated in human MSC isolated from the umbilical cord matrix (HEMSC) the expression of novel markers indicative of their stemness, as well as differentiative and immune properties [1]. HEMSC were cultured and subject to multiple molecular and morphological analyses to determine the expression of markers of interest. Undifferentiated HEMSC expressed im…

Introduction. Wharton’s jelly (WJ), the main constituent of umbilical cord, emerged as a reliable and uncontroversial source of mesenchymal stem cells (MSC). WJ-MSC show unique ability in crossing lineage borders, therefore being capable to trans-ifferentiate towards mature cytotypes derived from the three germ layers. As other fetal-associated cells, WJ-MSC express several immunomodulatory molecules, essential during the initial phases of human development and for the processes linked to the tolerance of the mother to the semiallogeneic embryo. Very few data are present in literature on the maintenance of the immune privilege of the naïve cells after performing differentiation. Our previou…
