ISOLATION AND PHENOTYPICAL CHARACTERIZATION OF MESENCHYMAL STEM CELLS FROM PRE-TERM HUMAN UMBILICAL CORD MATRIX

Recent patents and advances on isolation and cellular therapy applications of mesenchymal stem cells from human umbilical cord Wharton's jelly
2011
In recent years, important advances were made to clarify the biology and potential use of mesenchymal stem cells (MSC) in the therapy of a number of disorders. MSC are present in a number of tissues, ranging from adult bone marrow, to several adult organs, adipose tissue and, in the last years, the fetal-associated (also named as extraembryonic) tissues (e.g. placenta, amniotic membrane, umbilical cord). In particular, research on cells derived from mature umbilical cord, a tissue which is still discarded at birth, showed that mesenchymal stem cells can be successfully isolated from the Wharton’s jelly (WJ), the main constituent of this organ. This review will take in to account the patents…
Expression and localization of matrix metalloproteinases MMPs in human umbilical cord

Immunohistochemical and transcriptional expression of matrix metalloproteinases in full-term human umbilical cord and Human Umbilical Vein Endothelia…

Matrix metalloproteinases (MMPs) are extracellular zinc-dependent endopeptidases involved in the degradation and remodelling of extracellular matrix in physiological and pathological processes. MMPs also have a role on cell proliferation, migration, differentiation, angiogenesis and apoptosis. Umbilical cord is a special organ subjected to many changes during pre-natal life and whose cells can maintain a certain degree of plasticity also in post-natal period; for example recently they have been used as a source of stem cells. In this work we investigated the expression of MMPs in human umbilical cord and Human Umbilical Vein Endothelial Cells (HUVEC) though immunohistochemistry, RT-PCR and …
Cytocheratins Identification in Human Umbilical Cord at Term.
2009
Introduction. Cytokeratins (Cks) are the proteins that constitute intermediate filaments. 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. With this study we tried to make light on the pattern of expression of a wide range of CKs in human umbilical cord at term. Materials and methods. We investigated the expression of CKs through immunohistochemistry and RT-PCR assay. Results. AE1/AE3 antibody reacts with the basic CKs 1, 2, 3, 4, 5, 6, 7 and 8, and with the acidic CKs 10, 13, 14, 15, 16 and 19. The reactivity for this antibody is localized in the amniotic…
Expression of matrix metalloproteinases in full-term human umbilical cord and Human Umbilical Vein Endothelial Cells.
2010
Background. Matrix metalloproteinases (MMPs) are extracellular zinc-dependent endopeptidases involved in breakdown and remodelling of extracellular matrix in physiological and pathological processes. MMPs have also a role on cell proliferation, migration, differentiation, angiogenesis and apoptosis. Umbilical cord is a special organ subjected to many changes during pre-natal life and whose cells can maintain a certain degree of plasticity also in post-natal period; for example recently they have been used as a source of stem cells. For these reasons we believe it is interesting to investigate the expression of some remodelling enzymes in this tissue. Human Umbilical Vein Endothelial cells (…
