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…

Expression of cytokeratins in human umbilical cord at term

2009

Background. Cytokeratins are the proteins that costitute intermediate filaments. In the cytoplasm, keratin filaments extend from the nucleus to the plasma membrane. This link is important for the structural organization of the cytoplasm and for many cellular processes such as mitosis, cell movement, cell differentiation and adhesion. The pattern of expression of cytokeratins is frequently organ or tissue specific and depends mainly on the type of epithelium, the level of differentiation and the stage of development. The expression of cytokeratins in umbilical cord has been investigated by many groups, but these previous studies gave only fragmentary informations: each single study focused o…
