Mice cloned from skin cells [PDF]
Proceedings of the National Academy of Sciences, 2007 Adult stem cells represent unique populations of undifferentiated cells with self-renewal capacity. In many tissues, stem cells divide less often than their progeny. It has been widely speculated, but largely untested, that their undifferentiated and quiescent state may make stem cells more efficient as donors for cloning by nuclear transfer (NT). Here,

Free-living protozoa in two unchlorinated drinking water supplies identified by phylogenic analysis of 18S rRNA gene sequences [PDF]
, 2009 Free-living protozoan communities in water supplies may include hosts for Legionella pneumophila and other undesired bacteria and also pathogens. This study aimed at identifying free-living protozoa in two unchlorinated groundwater supplies using ...

Cloning of terminal transferase cDNA by antibody screening [PDF]
, 1984 A cDNA library was prepared from a terminal deoxynucleotidyltransferase-containing thymoma in the phage vector λgt11. By screening plaques with anti-terminal transferase antibody, positive clones were identified of which some had β-galactosidase-cDNA ...

Suitability of a CMV/EGFP cassette to monitor stable expression from human artificial chromosomes but not transient transfer in the cells forming viable clones [PDF]
, 2004 Human artificial chromosomes (HACs) were generated by transfer of telomerized PAC constructs containing alpha satellite DNA of various human chromosomes. To monitor which cells took up constructs and subsequently formed stable clones under blasticidin S (

Violation of cell lineage restriction compartments in the chick hindbrain [PDF]
, 1994 Previous cell lineage studies indicate that the repeated neuromeres of the chick hindbrain, the rhombomeres, are cell lineage restriction compartments. We have extended these results and tested if the restrictions are absolute. Two different cell marking

Immunology Today, 1985 The interaction of antigen with immunologically competent cells may lead either to the induction of an immune response or to a state of antigen specific unresponsiveness complete orpartial, which is often called immunological 'tolerance'. This is believed to be a major mechanism of discrimination between self and non-self(1-3).

Determinant of HIV-1 mutational escape from cytotoxic T lymphocytes. [PDF]
, 2003 CD8+ class I-restricted cytotoxic T lymphocytes (CTLs) usually incompletely suppress HIV-1 in vivo, and while analogous partial suppression induces antiretroviral drug-resistance mutations, epitope escape mutations are inconsistently observed.

Diagnostic Pathology, 2018 Background The translocation t(14;18)(q32;q21) is the genetic hallmark of follicular lymphoma (FL) and can be observed in 85–90% of cases. Whether the translocation is restricted to cells with germinal center B-cell phenotype or can be observed in other ...
