The effect of novel thiazole-derived small molecules on the self-renewal and differentiation of human multipotent neural progenitor cells

(i)                 RESEARCH IN PROGRESS

This research is looking at the potential of novel thiazole-derived small molecule compounds to be active in the differentiation process of neural progenitor cells. The SH-SY5Y cell line has been used as a ‘base-line’ neuronal differentiation model with which to screen the activity of 30 rationally designed small molecule compounds. Comparable activity of ‘hit’ compounds is to be screened in the human neural progenitor cell line. The ACEA xCelligence Real-Time Cell Analyser SP system is used for compound screening and determination of compound activity in real-time, followed by end-point fluorescent staining to determine cell viability and neurite outgrowth for the identification of differentiated cells.  Markers of developing neurons, identified by β-tubulin and Tyrosine hydroxylase expression, are identified using western blotting as well as immunofluorescence microscopy.
