Stem cells from umbilical cord Wharton's jelly from preterm birth have neuroglial differentiation potential.

Objective: The aim of the study is to determine the neuroglial differentiation potential of human Wharton's jelly-derived mesenchymal stem cells (WJ-MSCs) from preterm birth when compared to term delivery.

Study Design: The WJ-MSCs from umbilical cords of preterm birth and term controls were isolated and induced into neural progenitors. The cells were analyzed for neuroglial markers by flow cytometry, real-time polymerase chain reaction, and immunocytochemistry.

Homing of placenta-derived mesenchymal stem cells after perinatal intracerebral transplantation in a rat model.

Objective: The aim of this study is to assess early homing of placenta-derived stem cells after perinatal intracerebral transplantation in rats.

Study Design: Neonatal Wistar rats (2-4 days old) were anesthetized, and 250,000 human placenta-derived mesenchymal stem cells (MSC) injected into the lateral ventricle or the paraventricular white matter using a stereotactic frame. Donor MSC were detected by immunohistochemistry using an antihuman HLA-ABC antibody.

Placental microparticles, DNA, and RNA in preeclampsia.

Preeclampsia is a common disorder of the second half of pregnancy that complicates 2% to 7% of all pregnancies worldwide and remains a major cause of maternal and fetal morbidity and mortality. Although the origin of the disease is still elusive, population-based studies have suggested that it might implicate genetic, immunologic, or physiologic factors. On the other hand, there is no doubt that the placenta plays an important role in its development.
