  • As opposed to what previously shown for epithelial cell lines, DCSC did not reduce nYAP positivity as a function of cell density, when grown in serum containing medium, suggesting that soluble factors present in the serum could maintain the nuclear localization of YAP, independently from the cell density. (ung.si)
  • Currently JRM-001 is going through Phase III clinical trial in Japan to evaluate the improvement of cardiac function after standard surgical repair of the heart and the team is aiming for speedy approval and commercialization. (metcela.com)
  • By developing these pipelines in an integrated manner, Metcela will be able to bring seamless pipeline development for a wide range of cardiac diseases and, in the future, relish a wide range of synergies in terms of sharing manufacturing know-how and sales systems. (metcela.com)
  • Across biomedicine, there is a major drive to develop stem cell (SC) treatments for debilitating diseases. (ox.ac.uk)
  • These include bone marrow-derived cells, peripheral blood derived stem cells and skeletal myoblasts (3). (escardio.org)
  • Such a prospect is currently hampered, however, in part by an incompletely defined complex of molecular regulators of cardiac cell development and differentiation. (biomedcentral.com)
  • The development of a new, advanced modality, such as reducing adverse cardiac remodeling, promoting myocardial functions, and correcting molecular or genetic defects, is urgently required. (techbriefs.com)
  • miRNAs could thus be the best targets for understanding cardiac specialization during differentiation of human embryonic stem cells (hESCs). (biomedcentral.com)
  • Metcela will further expand discussions on strengthening collaboration by utilizing the know-hows of the two companies and applying Kidswell Bio's experience on establishing a master cell bank for stem cells from human exfoliated deciduous teeth (SHED) to VCF and CSC businesses. (metcela.com)
  • 21 Nov, 2007 10:54 am A huge advancement in stem cell research--and a stake in the heart of human cloning--was announced yesterday. (scitizen.com)
  • 18 Sep, 2007 12:13 pm Rice University researchers have engineered musculoskeletal cartilages with human embryonic stem cells, with the hope of eventually using the neotissue. (scitizen.com)
  • 6 Sep, 2007 12:57 pm British authorities decided yesterday to permit research that uses animal eggs to create human stem cells because of the limited supply of human eggs. (scitizen.com)
  • 27 Jun, 2007 06:08 pm Stem cells have the potential to become all the cells and tissues in the human body. (scitizen.com)
  • This approach could therefore micromass test, and the embryonic stem cell test (EST) provide a means to reduce the need for animal testing in human risk assessment practices. (cdc.gov)
  • In 2012, it was proposed that Isl-1 is not a marker for endogenous cardiac stem cells. (wikipedia.org)
  • We thus wondered how cells grow spatially during differentiation, so we labeled cells by expression of marker genes and found that cells expressing the same marker tended to occur in patches. (figshare.com)
  • Double staining for iron and CD68 (resident macrophage marker) showed that most of the iron-positive cells were cardiac macrophages at 4 weeks. (biomedcentral.com)
  • Moreover, Massan's trichrome staining shows increased amount of cardiac fibrosis in STZ-induced diabetic animals compared with control. (ucf.edu)
  • In this line, reporter gene assays with combinatorial treatment of 3i-1000 and the BET bromodomain inhibitor (+)-JQ1 demonstrated the cooperative role of GATA4 and BRD4 in the modulation of chamber-specific cardiac gene expression. (biomedcentral.com)
  • MicroRNAs (miRNAs) are small noncoding RNAs (~22 nucleotides in length) that regulate gene expression post-transcriptionally by imperfect binding to the 3′ untranslated region of target mRNAs in a wide variety of cell types. (biomedcentral.com)
