Hypothermia, currently the only effective treatment, leads to modest improvements, but new therapeutic strategies are required. Umbilical cord blood (UCB) mononuclear cells have potent anti\u2010inflammatory properties and may reduce neuropathology. This study examined whether autologous UCB mononuclear cells were neuroprotective when administered to newborn lambs at 12\u00a0h after birth asphyxia. At caesarean section, birth asphyxia was induced by clamping the umbilical cord until mean arterial blood pressure decreased to 18\u201320\u00a0mmHg. Asphyxia (<jats:italic>n<\/jats:italic>\u00a0=\u00a020) or control (<jats:italic>n<\/jats:italic>\u00a0=\u00a011) lambs were resuscitated and maintained, with magnetic resonance spectroscropy (MRS) performed at 12 and 72\u00a0h, and were then killed at 72\u00a0h. Cord blood was collected once the cord was clamped, and mononuclear cells were isolated and labelled fluorescently and administered to control (<jats:italic>n<\/jats:italic>\u00a0=\u00a03) or asphyxia (<jats:italic>n<\/jats:italic>\u00a0=\u00a08) lambs. Asphyxia induced a significant increase in cellular apoptosis (caspase\u20103 immunopositive) within all brain regions examined, including cortex, hippocampus, thalamus, striatum and subcortical white matter (<jats:italic>P<\/jats:italic>\u00a0&lt;\u00a00.01\u00a0<jats:italic>vs<\/jats:italic>. control). Additionally, asphyxia induced significant and widespread astrogliosis and increased inflammatory cells (activated microglia and macrophages). The administration of UCB mononuclear cells (asphyxia+UCB) significantly decreased neuronal apoptosis, astrogliosis and inflammation (<jats:italic>P<\/jats:italic>\u00a0&lt;\u00a00.05\u00a0<jats:italic>vs<\/jats:italic>. asphyxia alone). Asphyxia+UCB lambs also demonstrated decreased brain metabolites lactate:choline (<jats:italic>P<\/jats:italic>\u00a0=\u00a00.01) and lactate:<jats:italic>N<\/jats:italic>\u2010acetylaspartate (<jats:italic>P<\/jats:italic>\u00a0&lt;\u00a00.01) from 12 to 72\u00a0h, detected using MRS. Autologous UCB mononuclear cell treatment restores normal brain metabolism following perinatal asphyxia, and reduces brain inflammation, astrogliosis and neuronal apoptosis, supporting its use as a neuroprotective therapy following asphyxia.<\/jats:p><\/jats:sec>","DOI":"10.1113\/jp271104","type":"journal-article","created":{"date-parts":[[2015,11,3]],"date-time":"2015-11-03T08:42:45Z","timestamp":1446540165000},"page":"1421-1435","source":"Crossref","is-referenced-by-count":69,"title":["Cord blood mononuclear cells prevent neuronal apoptosis in response to perinatal asphyxia in the newborn lamb"],"prefix":"10.1113","volume":"594","author":[{"given":"James D.
