... of Dap, respectively. Finally, we show that the fate determinant factor, Tramtrack, downregulates Cyclin E expression and is probably involved in the exit of the cells from the cell cycle. * Author for correspondence (e-mail: [email protected] ) 18 2 2005 ©2005. 2005 BrdU...

... functional analysis. (2) Vital dye (DiI) labelling in vitro suggests that epiblast cells arrive in the PGE from anterior parts of the embryonic disc and then move within this area in a complex pattern of posterior, centripetal and anterior directions to form the primitive streak. (3) BrdU labelling shows...

... death Horizontal cell Amacrine cell NGF TrkA Chick BrdU Cells that undergo naturally occurring death has been found in the early and late developing retina ( Hughes and McLoon, 1979 ; Rager and Rager, 1978 ; Ulshafer and Clavert, 1979 ). Early cell death in chick embryo occurs during...

...E. J. Sanders; M. Varedi; A. S. French ABSTRACT Cell proliferation in the gastrulating chick embryo was assessed using two independent techniques which mark cells in S phase of the mitotic cycle: nuclear incorporation of bromodeoxyuridine (BrdU) detected immunocytochemically and immunolocalization...

... astrocytes, oligodendrocytes and their precursors. Between E16.5 and E18.5, two hours after a maternal injection of BrdU, the majority of proliferating cells were located in a discrete cluster at the ventral ventricular zone dorsal to the ventral midline region of the developing spinal cord. By contrast, 12...

... of lens fiber cells, (2) morphological abnormality of nuclei of lens fiber cells, (3) lack of eosinophilic granules in the central fiber cells and (4) rupture of lens capsule in the posterior region. We have immunohistologically examined, by means of an in vivo BrdU incorporation system, whether...

... the odontoblasts of incisor roots. Analysis of the distribution of bromodeoxyuridine (BrdU) incorporation indicated apparent correlations between TGF-β1 RNA expression and cell proliferation at the bud and cap stages but not at later stages of tooth development. Tissue recombination experiments of bud-staged (13...

... with embryonic cells in one clone. Further-more, BrdU labelling suggests that the embryonic neuroblast itself rather than one of its progeny resumes proliferation as a postembryonic neuroblast. A second type of clone consists of embryonic progeny only. 27 09 1990 © 1991 by Company of Biologists 1991...

... immunocytochemistry with antibodies against bromodeoxyuridine, BrdU (a thymidine analogue) and against opsin to determine when during the mitotic history of a cell the expression of opsin first occurred, taking a double labelled cell to be evidence of commitment to the rod cell fate. We found that the first double...

... growth, we developed a functional assay for cell proliferation using micromass culture and defined medium. Cell number was determined over a 4 day period and BrdU incorporation was used to determine the percentage of cells in S-phase. In defined medium, cell number progressively decreases...
