ScienceDaily (Feb. 10, 2012) — In a new study presented at the Society for Maternal-Fetal Medicine's annual meeting, The Pregnancy Meeting ™, in Dallas, Texas, researchers have reported that early transplantation of human placenta-derived mesenchymal stem cells into the lateral ventricles of neonatal rats with birth-related brain damage is possible, and that the donor cells can survive and migrate in the recipient's brain. The study was designed to have the rat's brain damage mimic brain injury in infants with very low birth weight. One of the major causes of neonatal brain damage is preterm delivery. Despite enormous efforts to prevent it, brain injury accounts for a major part of the clinical problems experienced by survivors of premature birth. The enormity of this problem is indicated by the occurrence of: cognitive, behavioral, attention related and/or socialization deficits in twenty-five to fifty percent of cases in this group; and major motor deficits in five to ten percent of cases in this group. The majority of neonatal encephalopathy cases are found in infants with a very low birth weight, and include both hypoxia-ischemia and inflammation, a double-hit. Approximately 63,000 infants are born in the United States with a very low birth weight (one … Continue reading →
