Immunohistochemical staining confirmed that these events occurred primarily in precursor cells rather than in postmitotic neurons. (jneurosci.org)
The morphological characteristics of these cells and immunohistochemical staining suggested that the coordinated events occurred in gap junction-coupled precursor cells. (jneurosci.org)

Glial cells are primarily produced in a second germinal zone, the subventricular zone that is located superficially to the VZ. (jneurosci.org)
This process occurs primarily through genesis of the correct number of each cell type. (org.es)

Melanoma in particular exhibits a high incidence of activating BRAF and NRAS mutations and such cells are addicted to the activity of these mutant oncoproteins. (babraham.ac.uk)
However, cancer cells overcome these controls, in particular by acquiring genetic mutations leading to the activation of oncogenes (pten, myc) or loss of tumor suppressors (p53) [ 1 ]. (hindawi.com)

Between fertilization and the eighth week of gestation, the embryo undergoes multiple cell divisions. (asu.edu)

Scientists consider stem cells a promising replacement for injured or diseased organs and tissues. (disabled-world.com)

In normal cells, the fate of pyruvate depends on many factors, one of which is oxygen availability. (hindawi.com)

A successful therapy must therefore eliminate these cells known to be highly resistant to apoptosis. (hindawi.com)

These are multipotent cells endowed with high migratory potential, that contribute to many tissues in the body. (inmg.fr)

In each hemi-segment, a set of neuroblasts produces neural cells by repeated asymmetrical and interiorly directed divisions. (biomedcentral.com)
With the currently available data, a common origin of pycnogonid neural stem cells and tetraconate neuroblasts remains unresolved. (biomedcentral.com)

Using biologically relevant elastic substrates to study cell function in vitro has proven beneficial, as the in vivo microenvironment usually is much softer than rigid plastic dishes. (5dok.org)
