Background and purpose: Preeclampsia is a medical condition in pregnancy that is determined by hypertension and proteinuria. Among many predisposing factors in pathophysiology of preeclampsia, the role of lipid peroxides is recently emphasized. The aim of this study was to evaluate the association of preeclampsia with maternal plasma and umbilical cord lipid concentration. Materials and method...

The aim of the study was to investigate the possibility of human umbilical cord mesenchymal stem cells (UC-MSCs) surviving and differentiating into hepatocyte-like cells in partially hepatectomized model rats. MSCs were isolated from human umbilical cord and cultured with collagenase digestion. Cell surface markers were detected and fifth generation UC-MSCs were labeled with PKH26. The partiall...

Background and Objective: Nowadays, although umbilical cord blood is a commonly used source of hematopoietic stem cell, its low frequency of these cells is the main factor limiting its clinical application. The transplantation of hematopoietic stem cells derived from placenta tissue along with umbilical cord blood cells of the same sample may be an appropriate approach to solve this problem. In...

Full-term human umbilical cord contains three blood vessels: two arteries coiled around a vein and surrounded by Wharton's jelly, a mucous tissue with few mesenchymal stromal cells and abundant extracellular matrix. Umbilical vessels lack innervations, thus endothelial cells must play a role in the control of blood flow. The aim of this study was to investigate in human umbilical cord the expre...

The development of the human umbilical cord blood transplants with hematopoietic repopulating cells has enabled some problems associated with bone marrow transplants to be solved. Frozen umbilical cord blood banks should facilitate the finding of suitable stem cell donors. However, further experience is necessary to develop the optimal method for collection, separation, storage and cryopreserva...

Umbilical cord blood is an alternative hematopoietic stem cell source for patients with hematologic diseases who can be cured by allogeneic hematopoietic cell transplantation. Initially, umbilical cord blood transplantation was limited to children, given the low cell dose infused. Both related and unrelated cord blood transplants have been performed with high rates of success for a variety of h...

PURPOSE OF REVIEW Umbilical cord haematopoietic stem cell transplantation for primary immunodeficiencies is examined with other developments in treatment. Cord blood biology is reviewed, and advantages and disadvantages of umbilical cord blood stem cell transplantation for primary immunodeficiencies discussed. Clinical outcome data and future developments are reviewed. RECENT FINDINGS Cord bl...

The Stillbirth Collaborative Research Network recently reported on the probable or possible cause of death of 512 stillbirths whose mothers consented to complete postmortem examination [1]. Umbilical cord accidents (UCA) represented 10% of stillbirths [1]. In Caucasians the UCA associated stillbirth rate was 13% and 4% in non-Hispanic black. 9% of stillbirths were due to hypertension and 8% due...
