Understanding the influence of substrate when growing tumorspheres
(BioMed Central, 2021-12)
Background: Cancer stem cells are important for the development of many solid tumors. These cells receive promoting and inhibitory signals that depend on the nature of their environment (their niche) and determine cell ...
Epidermal growth factor prevents thallium(I)- and thallium(III)-mediated rat pheochromocytoma (PC12) cell apoptosis
(Springer, 2017-03)
We have reported recently that the proliferation of PC12 cells exposed to micromolar concentrations of Tl(I) or Tl(III) has different outcomes, depending on the absence (EGF− cells) or the presence (EGF+ cells) of epidermal ...
A dynamic cell recruitment process drives growth of the Drosophila wing by overscaling the vestigial expression pattern
(Academic Press Inc Elsevier Science, 2020-06-15)
Organs mainly attain their size by cell growth and proliferation, but sometimes also grow through recruitment of undifferentiated cells. Here we investigate the participation of cell recruitment in establishing the pattern ...
Measurement of expansin activity and plant cell wall creep by using a commercial texture analyzer
(Pontificia Universidad Catolica de Valparaíso, 2017-03)
Background Expansins play an important role in cell wall metabolism and fruit softening. Determination of expansin activity is a challenging problem since it depends on measuring cell wall properties by using ad hoc ...
Perinatal DEHP exposure modulates pituitary estrogen receptor α and β expression altering lactotroph and somatotroph cell growth in prepuberal and adult male rats
(Pergamon-Elsevier Science Ltd, 2021-12)
Phthalates are synthetic chemicals widely used to make polyvinylchloride (PVC) soft and flexible. Of these, Di-(2-ethylhexyl) phthalate (DEHP) is the most commonly used, with high human exposure occurring as early as the ...
Following the footprints of variability during filopodial growth
(Springer, 2020-11)
Filopodia are actin-built finger-like dynamic structures that protrude from the cell cortex. These structures can sense the environment and play key roles in migration and cell–cell interactions. The growth-retraction cycle ...
ACTH cells of pituitary pars distalis of viscacha (Lagostomus maximus maximus): immunohistochemical study in relation to season, sex, and growth
(Elsevier, 2006-05)
Corticotrope or ACTH cells were immunohistochemically identiWed in the pituitary pars distalis (PD) of viscacha by using the polyclonal antiserum against ACTH (1–24). The localization, distribution, shape, percentage ...
Curcumin inhibits the growth, induces apoptosis and modulates the function of pituitary folliculostellate cells
(Karger, 2010-03)
The polyphenol curcumin (diferuloylmethane) is the active componenet of the spice plant Curcuma longa and has been shown to exert multiple actions on mammalian cells. We have studied its effect on folliculostellate (FS) ...
FSH and bFGF stimulate the production of glutathione in cultured rat sertoli cells
(Wiley Blackwell Publishing, Inc, 2009-06)
Migration of developing germ cells from the basal to the adluminal compartment of the seminiferous epithelium requires extensive tissue restructuring, resulting in the production of reactive oxygen species. Sertoli cells ...
Influence of individual cell motility on the 2D front roughness dynamics of tumour cell colonies
(Springer, 2014-06)
The dynamics of in situ 2D HeLa cell quasi-linear and quasi-radial colony fronts in a standard culture medium is investigated. For quasi-radial colonies, as the cell population increased, a kinetic transition from an ...
