1. NS1 codon usage adaptation to humans in pandemic Zika virus
BACKGROUND Zika virus (ZIKV) was recognised as a zoonotic pathogen in Africa and southeastern Asia. Human infections were infrequently reported until 2007, when the first known epidemic occurred in Micronesia. After 2013, the Asian lineage of ZIKV spread along the Pacific Islands and Americas, causing severe outbreaks with millions of human infections. The

2. Participação das selectinas nas interações entre células angiogênicas da medula óssea e endotélio de músculos isquêmicos de membros inferiores em modelo murino.
The stimulation of vascular growth by angiogenic stem cells transplantation is a promising alternative for the treatment of PAD. Adhesive mechanisms governing progenitor/stem cell trafficking through the microcirculation of ischemic muscles are broadly unknown. The aim of this work was to evaluate the involvement of selectins on interactions between transpla

3. A origem do milho : a identificação de Saccharum como um dos provaveis parentais alotetraploides / The origin of maize: Saccharum as one of the allotetraploid progenitors
The sequencing of ESTs (expressed sequence tags) and its organization in databases constitute powerful tools to identify genes of interest in certain tissues and/or cell types. In this work we have created a database of ESTs expressed in diverse maize tissues called MAIZEST. MAIZEST contains 227,431 ESTs coming from over 30 different maize tissues, 64,357 of

4. Resistance of sorghum hybrids to Colletotrichum sublineolum: previsibility by lineage progenitor reaction. / ResistÃncia de hÃbridos de sorgo a Colletotrichum sublineolum: previsibilidade por meio da reaÃÃo de linhagens progenitoras
A antracnose (Colletotrichum sublineolum Henn. in Kab. &BubÃk), està disseminada em todas as regiÃes produtoras de sorgo no paÃs. Foi objetivo deste trabalho, caracterizar a diversidade populacional de C. sublineolum em locais de ocorrÃncia de severas epidemias da doenÃa, identificar combinaÃÃes entre linhagens elite capazes de gerar hÃbridos de sor

5. Lineage commitment in the progeny of murine hematopoietic preprogenitor cells: Influence of thrombopoietin and interleukin 5
Normal mouse marrow cells were stimulated by stem cell factor (SCF) to form dispersed or multicentric blast colonies containing progenitor cells committed to various hematopoietic lineages. Combination of the eosinophil-specific regulator interleukin 5 with SCF increased the frequency of colonies containing eosinophil-committed progenitor cells with multicen

6. Enforced expression of EBF in hematopoietic stem cells restricts lymphopoiesis to the B cell lineage
Mice deficient in early B cell factor (EBF) are blocked at the progenitor B cell stage prior to immunoglobulin gene rearrangement. The EBF-dependent block in B cell development occurs near the onset of B-lineage commitment, which raises the possibility that EBF may act instructively to specify the B cell fate from uncommitted, multipotential progenitor cells

7. Structure of clonal and polyclonal cell arrays in chimeric mouse retina.
One of the most striking results of recent cell-lineage studies of vertebrate retina is the marked variability in the size and types of clones marked by retroviral transfection and dye injection of embryonic progenitor cells. Is this variability due to microenvironmental modulation of cell determination, to lineage restriction, or to experimental perturbatio

8. Lineage commitment of hemopoietic progenitor cells in developing blast cell colonies: influence of colony-stimulating factors.
In clonal cultures of normal mouse marrow cells, combination of granulocyte, granulocyte-macrophage, or multipotential colony-stimulating factor (G-CSF, GM-CSF, or multi-CSF, respectively) with stem cell factor (SCF) did not alter the number of blast colonies stimulated to develop compared with SCF alone but induced an up to 25-fold increase in their mean ce

9. Commitment to natural killer cells requires the helix–loop–helix inhibitor Id2
We have previously described how T and natural killer (NK) lineage commitment proceeds from common T/NK progenitors (p-T/NK) in the murine fetal thymus (FT), with the use of a clonal assay system capable of discriminating p-T/NK from unipotent T or NK lineage-committed progenitors (p-T and p-NK, respectively). The molecular mechanisms controlling the co

10. Molecular Signatures of Self-Renewal, Differentiation, and Lineage Choice in Multipotential Hemopoietic Progenitor Cells In Vitro
The molecular mechanisms governing self-renewal, differentiation, and lineage specification remain unknown. Transcriptional profiling is likely to provide insight into these processes but, as yet, has been confined to “static” molecular profiles of stem and progenitors cells. We now provide a comprehensive, statistically robust, and “dynamic” analysi

11. Immunoglobulin heavy-chain and CD3 delta-chain gene enhancers are DNase I-hypersensitive in hemopoietic progenitor cells.
Multipotential interleukin 3-dependent non-immortalized murine hemopoietic progenitor cells have DNase I-hypersensitive sites in the immunoglobulin heavy-chain and CD3 delta enhancers and transcribe germ-line T-cell antigen receptor gamma-chain (TCR gamma), but not IgM or TCR beta, genes. Induction of myeloid differentiation in these cells clones down expres

12. Oligodendrocyte lineage genes (OLIG) as molecular markers for human glial brain tumors
The most common primary tumors of the human brain are thought to be of glial cell origin. However, glial cell neoplasms cannot be fully classified by cellular morphology or with conventional markers for astrocytes, oligodendrocytes, or their progenitors. Recent insights into central nervous system tumorigenesis suggest that novel molecular markers might be f
