Título: | Towards the Maturation and Characterization of Smooth Muscle Cells Derived from Human Embryonic Stem Cells | Autor: | Vazão, Helena Neves, Ricardo Pires das Grãos, Mário Ferreira, Lino |
Data: | 10-Mar-2011 | Editora: | Public Library of Science | Citação: | VAZÃO, Helena - Towards the Maturation and Characterization of Smooth Muscle Cells Derived from Human Embryonic Stem Cells. "PLoS ONE". ISSN 1932-6203. 6:3 (2011) e17771 | Título da revista, periódico, livro ou evento: | PLoS ONE | Volume: | 6 | Número: | 3 | Resumo: | In this study we demonstrate that CD34+ cells derived from human embryonic stem cells (hESCs) have higher smooth muscle cell (SMC) potential than CD34− cells. We report that from all inductive signals tested, retinoic acid (RA) and platelet derived growth factor (PDGFBB) are the most effective agents in guiding the differentiation of CD34+ cells into smooth muscle progenitor cells (SMPCs) characterized by the expression of SMC genes and proteins, secretion of SMC-related cytokines, contraction in response to depolarization agents and vasoactive peptides and expression of SMC-related genes in a 3D environment. These cells are also characterized by a low organization of the contractile proteins and the contractility response is mediated by Ca2+, which involves the activation of Rho A/Rho kinase- and Ca2+/calmodulin (CaM)/myosin light chain kinase (MLCK)-dependent pathways. We further show that SMPCs obtained from the differentiation of CD34+ cells with RA, but not with PDGFBB, can be maturated in medium supplemented with endothelin-1 showing at the end individualized contractile filaments. Overall the hESC-derived SMCs presented in this work might be an unlimited source of SMCs for tissue engineering and regenerative medicine. | URI: | https://hdl.handle.net/10316/15680 | ISSN: | 1932-6203 | DOI: | 10.1371/journal.pone.0017771 | Direitos: | openAccess |
