WebJul 16, 2024 · Biological pacemakers derived from pluripotent stem cell (PSC) have been considered as a potential therapeutic surrogate for sick sinus syndrome. So it is essential to develop highly efficient strategies for enrichment of sinoatrial node-like cells (SANLCs) as seed cells for biological pacemakers. WebGeneration of human SAN-like cells from hESCs We sought to develop a protocol that maximizes the generation of pluripotent stem cell-derived SAN pacemaker lineages (PSC-SAN). Based on previous reports (Hoogaars et al., 2007; Ionta et al., 2015; McNally and Svensson, 2009), SAN progenitors are expected to be enriched for expression of key pace- bound in malay https://lovetreedesign.com
