Hydration of transfer RNA molecules: a crystallographic study.

abstract：:Embryonic stem cells (ESCs) are capable of unlimited self-renewal and differentiation into multiple cell types. Recent large-scale analyses have identified various cell surface molecules on ESCs. Some of them are considered to be beneficial markers for characterization of cellular phenotypes and/or play an essential r...
