Aug 29, 2003 - Methods for directly turning a somatic cell type into another type (a process referred to as transdifferentiation) would be beneficial for producing replacement cells for therapeutic applications. Adult stem cells have been shown…

Aug 6, 2013 - For symmetrically dividing cells, large variations in the cell cycle time are typical, even among clonal cells. The consequence of this variation is important in stem cell differentiation, tissue and organ size…

Aug 22, 1986 - The regulatory biology of antibody formation entered a new phase of study with the development of selective theories of immunity. The discovery of the ‘one cell - one antibody’ dogma and the demonstration that only a small minority of B cells

Nov 5, 2013 - Asymmetric cell divisions (ACDs) result in two unequal daughter cells and are a hallmark of stem cells. ACDs can be achieved either by asymmetric partitioning of proteins and organelles or by asymmetric cell fate…

Mar 23, 1987 - Three forms of viral hepatitis can be distinguished serologically. Hepatitis A virus is a picornavirus, which is being studied increasingly after its propagation in cell cultures. The B virus (HBV) is the prototype of a family now termed hepadna

Feb 5, 2017 - Evolving multicellularity is easy, especially in phototrophs and osmotrophs whose multicells feed like unicells. Evolving animals was much harder and unique; probably only one pathway via benthic ‘zoophytes’ with pelagic ciliated larvae allowed

Mar 5, 2018 - Telomeres are repeating DNA found at the ends of chromosomes that, in the absence of restorative processes, shorten with cell replications and are implicated as a cause of senescence. It appears that sperm telomere length (TL) increases with age in

Nov 6, 2014 - The encapsulation of living mammalian cells within a semi-permeable hydrogel matrix is an attractive procedure for many biomedical and biotechnological applications, such as xenotransplantation, maintenance of stem cell phenotype and bioprinting of

Jan 31, 2016 - The human T-cell repertoire is complex and is generated by the rearrangement of variable (V), diversity (D) and joining (J) segments on the T-cell receptor (TCR) loci. The T-cell repertoire demonstrates self-similarity in terms clonal frequencies
