Recent patents and advances in hepatocyte-like cells differentiation by mesenchymal stem cells
2013
Chronic liver diseases constitute one of the main causes of death in western countries. Orthotopic liver transplantation still remains the final therapeutic approach to these diseases, but alternative therapeutic strategies are actively researched. Hepatocyte transplantation is considered a promising approach, even if this technique presents many limitations. These factors boosted the research for alternative cell sources to derive functional hepatocytes. In the last years, research on basic biology and differentiative ability of adult, embryonic and perinatal stem cells has constantly increased. The term "perinatal" indicates stem cell populations derived from foetal sources such as placen…
The expression of CD68 in human umbilical cord mesenchymal stem cells: new evidences of presence in non-myeloid cell types.
2009
Since their first identification in bone marrow [2],MSC have attracted much attention for thei r potential todifferentiate towards several mature tissues. The efforts ofthe researchers aimed in finding new tissues, whichshould provide adequate cell numbers for regenerativemedicine applications (and between them, extraembryonicsources as umbilical cord and amniotic membrane, arebeing viewed with extreme interest).
Morphological assessment of the umbilical cord with three-dimensional ultrasonography
2002
ABSTRACTThe long cylindrical cord covered by a layer of amnion that extends from the umbilicus of the fetus to the fetal surface of the placenta is known as the umbilical cord, or, in older medical textbooks, as funiculis umbilicalis. The two umbilical arteries extend as branches of the internal iliac arteries that emerge from the fetal body at the umbilicus, and run a helical course through the umbilical cord carrying venous blood to the placenta. In most normal placentas, the umbilical arteries anastomose within 2 cm of insertion into the placenta. The fetal umbilical vein emerges from the placenta and carries oxygenated blood to the fetus. The cord vessels are supported by a matrix of my…
Recent Advances in Derivation of Functional Hepatocytes from Placental Stem Cells
2013
Abstract: End-stage liver diseases are one of the leading causes of death in the world. Often orthotopic liver transplantation represents the final therapeutic choice. The limits of this approach are the scarcity of donor livers available, and the many side effects related to the administration of immune suppressants to the patients. Cellular therapy for liver diseases is increasingly being viewed as a promising strategy to provide hepatocytes to replenish the parenchymal cells of the organ. This technique suffers of some important limitations, such as the difficulty in isolating sufficient cell numbers (e.g. when adult or foetal hepatocytes are used for transplantation), the limited viabil…
