Expression of nestin has been suggested to be a characteristic of pancreatic islet stem cells. To determine whether nestin is indeed expressed in such putative cells during embryonic development, or in the adult pancreas after injury, we performed a cell l ...
Intermediate filaments (IFs), together with actin filaments and microtubules, compose the cytoskeleton. Among other functions, Ts impart mechanical stability to cells when exposed to mechanical stress and act as a support when the other cytoskeletal filame ...
We have previously shown that glial cell line-derived neurotrophic factor (GDNF), in addition to promoting the survival of dopaminergic neurons in cultures from embryonic rat ventral mesencephalon,also increases the activity of choline acetyltransferase (C ...
We describe in this document our preliminary results regarding the tracking of dendrites spreading from a neuron in confocal microscope im- ages. When using a small number of image layers, we obtain good results by combining a EM-based local estimate of th ...
Recent evidence suggests that lactate could be a preferential energy substrate transferred from astrocytes to neurons. This would imply the presence of specific transporters for lactate on both cell types. We have investigated the immunohistochemical local ...
