One of the daughter cells retains the number of future divisions & will produce more organ specific cells. Induced pluripotent stem cells (also known as iPS cells or iPSCs) are a type of pluripotent stem cell that can be generated directly from a somatic cell. Advantages of the applications IPSCs in regenerative medicine, Can be generated from the patient's own cells, Disease specific IPSC lines that have been established, These cells have been generated from samples of patients with a variety of diseases such as: neurodegenerative, hematopoietic, metabolic and cardiovascular diseases, Advantages of IPSC - based disease modeling, I PSCs can be patient specific or disease specific, so called "disease in a dish", Advantages of IPS cells for drug Screening, Traditional drug development relied heavily on cell line-based compounds screening an animal-based testing, Applications of IPS cell technology in animal biotechnology, Can be used for genetic engineering in animals to generate disease models and to produce animals for useful substances, such as enzymes, that are deficient in patients with genetic diseases, Applications of IPSC technology in basic sciences. How do you know if you're iPS cells are good? What is the source of Embryonic stem cells. Which stem cells are maintained & propagated in culture forever? 4. Hypothesized that a combination of multiple factors are needed to maintain the poor potency of ESC's would reprogram somatic cells into the embryonic state, Mouse IPS cells can be induced from MEFs by four factors, Combination of the 10 gene alone produce more IPS cells than transduction of all 24 genes did. Specialized cells that continually self-divide & generate progeny cells for organ formation & maintenance. Additionally, advances with embryonic stem cells helped to support research progress with iPS cells, because iPS cells and embryonic stem cells share traits associated with pluripotency. Gravity.
