Culturas alternativas para pluripotentes estaminais humanas produção de células, Manutenção e Análise Genética

Overview

This article presents a novel method for culturing human pluripotent stem cells (hPSCs) using non-colony type monolayer (NCM) growth of dissociated single cells. The approach employs Rho-associated kinase inhibitors and laminin isoform 521 (LN-521) to facilitate the generation of large quantities of homogeneous hPSCs, which are essential for genetic manipulation and drug discovery.
