Mapping proteoglycan functions with glycosidases

Methods Mol Biol. 2015:1229:443-55. doi: 10.1007/978-1-4939-1714-3_34.

Abstract

The intrinsic and extrinsic factors that contribute to stem and neuronal precursor cell maintenance and/or differentiation remain poorly understood. Proteoglycans, major residents of the stem cell microenvironment, modulate key signaling cues and are of particular importance. We have taken a loss-of-function approach, by developing a library of bacterial lyases and sulfatases to specifically remodel the ECM and test the functional role of glycosaminoglycans (GAGs) in cell self-renewal, maintenance, and differentiation.
