Induced pluripotent stem cells (iPSCs) are reprogrammed cells that have features similar to embryonic stem cells, such as the capacity of self-renewal and differentiation into many types of cells, including cardiac myocytes. Although initially the reprogramming efficiency was low, several improvements in reprogramming methods have achieved robust and efficient generation of iPSCs without genomi...
BACKGROUND Cardiomyocytes differentiated from human pluripotent stem cells can serve as an unexhausted source for a cellular cardiac disease model. Although small molecule-mediated cardiomyocyte differentiation methods have been established, the differentiation efficiency is relatively unsatisfactory in multiple lines due to line-to-line variation. Additionally, hurdles including line-specific ...
The anterior heart field (AHF) encompasses a niche in which mesoderm-derived cardiac progenitors maintain their multipotent and undifferentiated nature in response to signals from surrounding tissues. Here, we investigate the signaling mechanism that promotes the shift from proliferating cardiac progenitors to differentiating cardiomyocytes in chick embryos. Genomic and systems biology approach...
There is a growing interest in using paper as a biomaterial scaffold for cell-based applications. In this study, we made the first attempt to fabricate a paper-based array for the culture, proliferation, and direct differentiation of human induced pluripotent stem cells (hiPSCs) into functional beating cardiac tissues and create "a beating heart on paper." This array was simply constructed by b...
AIMS The Wnt/frizzled (Fzd) signal transduction cascade has been implicated in the proliferation, differentiation, and migration of many cell types, but the role of this pathway in cardiac fibroblast differentiation is not known. Our lab previously showed an up-regulation of Fzd-1 and -2 expression in myofibroblasts after myocardial infarction (MI), indicating a potential role for the Fzd recep...
Background and Objective: In recent decades, stem cell therapy has been introduced as a novel therapeutic approach for patients suffering from cardiac disorders. Recently, identification of menstrual blood-derived stem cells (MenSCs) as a unique source of stem cell with some characteristics as well as ease of access, high proliferative ability and renewability has created enormous promise for c...
We show that loss of beta1 integrin function affects connexin (Cx) expression in embryonic stem (ES) cell-derived cardiomyocytes. Both loss of beta1 integrin function and inhibition of integrin clustering by RGD peptides in wild type ES cells correlated with upregulated expression of gap junctional proteins in ES-derived cardiomyocytes. The upregulation of connexin transcript levels in beta1 in...
