Telocytes (TCs) are cells defined by their long and moniliform processes termed telopodes. They were previously identified in the endocardium and express neural markers, such as nestin and neuron-specific enolase (NSE). Previous studies found a positive expression of neuro-filaments in endocardial endothelial cells, and a positive expression of nestin in cardiac side population (CSP) progenitor...
objective(s): in the past few decades, variety of foetal, embryonic and adult stem and progenitor cells have been tried with conflicting outcome for cell therapy of central nervous system injury and diseases. cellular characteristics and functional plasticity of globose basal stem cells (gbcs) residing in the olfactory epithelium of rat olfactory mucosa have not been studied in the past by the ...
In the last few years we have witnessed one of most extraordinary revolutions in cardiovascular medicine, namely, an explosion of basic and clinical studies that support the notion that the diseased heart can be repaired by administration of stem cells, resulting in formation of functional new myocytes and vessels. Although the mechanism by which cell therapy improves cardiac function and anato...
MicroRNAs (miRNAs) are genomically encoded small RNAs that hybridize with messenger RNAs, resulting in degradation or translational inhibition of targeted transcripts. The potential for miRNAs to regulate cell-lineage determination or differentiation from pluripotent progenitor or stem cells is unknown. Here, we show that microRNA1 (miR-1) is an ancient muscle-specific gene conserved in sequenc...
in recent years transdifferentiation technology has enabled direct conversion of human fibroblasts to become a valuable, abundant and accessible cell source for patient-specific induced cell generation in biomedical research. the majority of transdifferentiation approaches rely upon viral gene delivery which due to random integration with the host genome can cause genome instability and tumorig...
The characterisation of biomaterials for cardiac tissue engineering applications is vital for the development of effective treatments for the repair of cardiac function. New ‘smart’materials developed from conductive polymers can provide dynamic benefits in supporting and stimulating stem cells via controlled surface properties, electrical and electromechanical stimulation. In this study we inv...
During heart development the second heart field (SHF) provides progenitor cells for most cardiomyocytes and expresses the homeodomain factor Nkx2-5. We now show that feedback repression of Bmp2/Smad1 signaling by Nkx2-5 critically regulates SHF proliferation and outflow tract (OFT) morphology. In the cardiac fields of Nkx2-5 mutants, genes controlling cardiac specification (including Bmp2) and ...
BACKGROUND Heart development is tightly regulated by signaling events acting on a defined number of progenitor and differentiated cardiac cells. Although loss of function of these signaling pathways leads to congenital malformation, the consequences of cardiac progenitor cell or embryonic cardiomyocyte loss are less clear. In this study, we tested the hypothesis that embryonic mouse hearts exhi...
In the past few years it has been established that the heart contains a reservoir of stem and progenitor cells. These cells are positive for various stem/progenitor cell markers (Kit, Sca-1, Isl-1, and Side Population (SP) properties). The relationship between the various cardiac stem cells (CSC) and progenitor cells described awaits clarification. Furthermore, they may open a new therapeutic s...
Transcription factor Lbx1 is known to play a role in the migration of muscle progenitor cells in limb buds and also in neuronal determination processes. In addition, involvement of Lbx1 in cardiac neural crest-related cardiogenesis was postulated. Here, we used mouse embryonic stem (ES) cells which have the capacity to develop into cells of all three primary germ layers. During in vitro differe...
