dc.description.abstractThis report describes novel thiol-modified N-acetylmannosamine (ManNAc) analogs that extend metabolic glycoengineering (MGE) applications of Ac5ManNTGc, a non-natural monosaccharide that metabolically installs the thio-glycolyl of sialic acid into human glycoconjugates. We previously found that Ac5ManNTGc elicited non-canonical activation of Wnt signaling in human embryoid body derived (hEBD) cells but only in the presence of a high affinity, chemically compatible scaffold. Our new analogs Ac5ManNTProp and Ac5ManNTBut overcome the requirement for a complementary scaffold by displaying thiol groups on longer, N-acyl linker arms, thereby presumably increasing their ability to interact and crosslink with surrounding thiols. These new analogs showed increased potency in human neural stem cells (hNSCs) and human adipose stem cells (hASCs). In the hNSCs, Ac5ManNTProp upregulated biochemical endpoints consistent with Wnt signaling in the absence of a thiol-reactive scaffold. In the hASCs, both Ac5ManNTProp and Ac5ManNTBut suppressed adipogenic differentiation, with Ac5ManNTBut providing a more potent response, and they did not interfere with differentiation to a glial lineage (Schwann cells). These results expand the horizon for using MGE in regenerative medicine by providing new tools (Ac5ManNTProp and Ac5ManNTBut) for manipulating human stem cells.en_US
