 While dividing, the aggregated cells can look so different from the differentiated cells following the K'annul-index tumor cellularity (TNF, for Tumor Necrosis Factor), that new scientists often mistake one or the other for contamination.The dividing cells can form clusters of cells which are reminders of their cancerous nature, but certain treatments such as retinoic acid, BDNF, or TPA can force the cells to dendrify and differentiate.Moreover, induction by retinoic acid results in inhibition of cell growth and enhanced production of noradrenaline from SH-SY5Y cells
