What is transfection plasmid?
Plasmids are small circular DNA molecules that naturally occur in bacteria, and are actually used by the bacteria to transfer genetic information. The mechanism of adding a DNA plasmid into a mammalian cell is known as plasmid transfection.
Can you transfect IPSC?
2. Transfection of human iPSCs with GeneJuice. Cells (grown on 6-well plates) should be approximately 40 -50% confluent on the day of transfection to achieve optimal transfection efficiency. It is not necessary to change the cell medium until the next day.
How does PEI work transfection?
As with most transfection reagents, PEI-mediated transfection involves the formation of nanoparticles (polyplexes) which are obtained by its mixing with plasmid DNA. A short incubation period that allows polyplexes to reach their optimal size is performed prior to their addition to the culture.
What are the differentiation of cardiomyocytes?
Current methods for PSC differentiation into cardiomyocytes can be divided into three categories: (i) differentiation via co-culture with mouse visceral endoderm-like (END-2) stromal cells, (ii) EB differentiation in suspension, and (iii) 2D monolayer differentiation.
What are cardiomyocytes made of?
The individual cardiac muscle cell (cardiomyocyte) is a tubular structure composed of chains of myofibrils, which are rod-like units within the cell. The myofibrils consist of repeating sections of sarcomeres, which are the fundamental contractile units of the muscle cells.
What are the different transfection methods?
Transfection methods include various approaches (physical and chemical methods) that are carried out by non-viral techniques – electroporation, calcium phosphate exposure, liposome-based transfection that allow to deliver cargo molecules through cellular membrane without any permanent damage to the cell.
What causes cardiomyocytes to contract?
Contraction in cardiac muscle occurs due to the the binding of the myosin head to adenosine triphosphate ( ATP ), which then pulls the actin filaments to the center of the sarcomere, the mechanical force of contraction.
What is the difference between embryonic and induced pluripotent stem cells?
Embryonic stem (ES) cells are pluripotent stem cells derived from the inner cell mass of preimplantation embryos. Induced pluripotent stem (iPS) cells can be generated by somatic cell reprogramming following the exogenous expression of specific transcription factors (Oct-3/4, KLF4, SOX2, and c-Myc).
