Neural precursors (NPs) derived from ventral mesencephalon (VM) normally generate dopaminergic (DA) neurons in vivo but lose their potential to differentiate into DA neurons during mitogenic expansion in vitro, hampering their efficient use as a transplantable and experimental cell source. Because embryonic stem (ES) cell-derived NPs (ES NP) do not go(More)
AP-2 family transcription factors are essential for development and morphogenesis of diverse tissues and organs, but their precise roles in specification of neural crest stem cell (NCSC)-derived cell types have not been determined. Among three members known to be expressed in the NCSC (i.e. AP-2alpha, AP-2beta, and AP-2gamma), we found that only AP-2beta is(More)
BACKGROUND The incidence of cutaneous squamous cell carcinoma (cSCC) is increasing. Although most patients achieve complete remission with surgical treatment, those with advanced disease have a poor prognosis. The American Joint Committee on Cancer (AJCC) is responsible for the staging criteria for all cancers. For the past 20 years, the AJCC cancer staging(More)
Both fetal ventral mesencephalic (VM) and embryonic stem (ES) cell-derived dopamine neurons have been used successfully to correct behavioral responses in animal models of Parkinson's disease. However, grafts derived from fetal VM cells or from ES cells contain multiple cell types, and the majority of these cells are not dopamine neurons. Isolation of ES(More)
The MRL mouse is unique in its capacity for regenerative healing of wounds. This regenerative ability includes complete closure, with little scarring, of wounds to the ear pinna and repair of cardiac muscle, without fibrosis, following cryoinjury. Here, we examine whether neurogenic zones within the MRL brain show enhanced regenerative capacity. The largest(More)
BACKGROUND The number of uninsured children in the USA is increasing while the impact on children's health of being uninsured remains largely uncharacterized. We analyzed data from more than 23 million US children to evaluate the effect of insurance status on the outcome of US pediatric hospitalization. METHODS In our analysis of two well-known large(More)
The homeodomain transcription factor Phox2b is one of the key determinants involved in the development of noradrenergic (NA) neurons in both the central nervous system (CNS) and the peripheral nervous system (PNS). Using yeast two-hybrid screening, we isolated a Phox2b interacting protein, Trim11, which belongs to TRIM (Tripartite motif) or RBCC proteins(More)
BACKGROUND Rashkind balloon atrial septostomy is a common cardiac procedure aimed at improving systemic oxygenation in newborns with cyanotic congenital cardiac defects, such as transposition of the great arteries. Recent reports on the safety of this procedure were from limited series at single institutions. We analysed two complementary national databases(More)
