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 ...
Identification and culture of proliferative cells in abnormal Taenia solium larvae: Role in the development of racemose neurocysticercosis
(Public Library of Science, 2021)
Racemose neurocysticercosis is an aggressive disease caused by the aberrant expansion of the cyst form of Taenia solium within the subarachnoid spaces of the human brain and spinal cord resulting in a mass effect and ...
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 ...
Loss of prolyl hydroxylase-2 in myeloid cells and T-lymphocytes impairs tumor development
(Wiley, 2013)
The tumor microenvironment plays a pivotal role during cancer development and progression. The balance between suppressive and cytotoxic responses of the tumor immune microenvironment has been shown to have a direct effect ...
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 ...
Mast Cell Kinetics during Tumor Growth
(Karger, 1990)
The behavior of mast cells was studied during tumor growth. Sarcoma 13, and normal syngeneic kidney, as control, were implanted subcutaneously in BALBc mice. The number of mast cells in the hypodermis and peritumoral tissue ...
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 ...
