In vitro characterization of embryionic ST14A-cells

Int J Neurosci. 2008 Nov;118(11):1489-501. doi: 10.1080/00207450701769257.

Abstract

The embryonic striatal temperature sensitive immortalized ST14A-cell line was characterized in vitro by immunocytochemistry when cultured at 33 degrees C and at nonpermissive temperature of 39 degrees C for up to 14 days. At 33 degrees C in DMEM/10% FCS, cells proliferated, were extensively expressing the neural progenitor cell markers nestin and vimentin contrary to neuronal markers. However, when cultured at 39 degrees C the proliferation was delayed and cells began to increase the expression of neuronal markers, followed by a decrease of nestin and vimentin. In serum-free medium the process of neuronal differentiation became more obvious, indicating the potential to use these cells for experimental restorative therapies.
