Primordial Germ Cell-Like Cells Differentiated In Vitro From Skin-Derived Stem Cells, Katja Linher, Paul Dyce, Julang Li
Paul W. Dyce
Background We have previously demonstrated that stem cells isolated from fetal porcine skin have the potential to form oocyte-like cells (OLCs) in vitro. However, primordial germ cells (PGCs), which must also be specified during the stem cell differentiation to give rise to these putative oocytes at more advanced stages of culture, were not systematically characterized. The current study tested the hypothesis that a morphologically distinct population of cells derived from skin stem cells prior to OLC formation corresponds to putative PGCs, which differentiate further into more mature gametes.
Methodology/Principal Findings When induced to differentiate in an appropriate microenvironment, a subpopulation …

Decarboxylation Of L-Dopa And 5-Hydroxytryptophan In Dispersed Rat Pancreas Acinar Cells, E. Yu, L. Stern, A. Tenenhouse
Decarboxylation Of L-Dopa And 5-Hydroxytryptophan In Dispersed Rat Pancreas Acinar Cells, E. Yu, L. Stern, A. Tenenhouse
Edward Yu
Amino acid decarboxylation activity in dispersed rat pancreas acinar cells and fractions derived by differential centrifugation of homogenate of these cells was studied. The rate of decarboxylation was measured by determining the rate of production of the [3H]-amine from [3H]-amino acid or the rate of production of 14CO2 from the [14C]-carboxy-labelled amino acid. Only the hydroxylated amino acids L-dopa and 5-hydroxytryptophan are decarboxylated by intact dispersed pancreas acinar cells or cell homogenates at all pH values and amino acid concentrations tested. The decarboxylase activity is located exclusively in the cell cytosol. Each substrate competitively inhibits the decarboxylation of the other …

Polymorphisms Of Delta-Aminolevulinic Acid Dehydratase (Alad) And Peptide Transporter 2 (Pept2) Genes In Children With Low-Level Lead Exposure, Christina Sobin, Marisela Gutierrez, Heather Alterio
Polymorphisms Of Delta-Aminolevulinic Acid Dehydratase (Alad) And Peptide Transporter 2 (Pept2) Genes In Children With Low-Level Lead Exposure, Christina Sobin, Marisela Gutierrez, Heather Alterio
Christina Sobin, Ph.D.
Low-level lead exposure during early childhood has long been associated with altered neurocognitive development and diminished cognitive functions. Over nine thousand U.S. industrial facilities annually emit significant amounts of lead, creating exposure risk particularly for minority children. The mechanisms by which low-level lead exerts neurotoxic effects are poorly understood. Once absorbed, the only intervention is source removal, thus primary prevention is key. Genetic biomarkers could provide an efficient means of identifying children at greatest risk. Common functional variants of genes that alter lead’s neurotoxic potential have been identified and include delta-aminolevulinic acid dehydratase (ALAD2) and peptide transporter 2 (PEPT2*2). These …
