Cystic Fibrosis (CF) is a progressive genetic disease that affects the lungs and digestive system as well as many other organ systems. It causes thick, sticky mucus to build up in the lungs, which leads to life-threatening lung infections. Cystic fibrosis is caused by mutations in the gene that produces the cystic fibrosis transmembrane conductance regulator (CFTR) protein. This protein is responsible for regulating the flow of salt and fluids in and out of the cells in different parts of the body. Induced pluripotent Stem (iPS) cells might offer hope for curing CF. Describe how iPS cell technology can be used to treat individuals suffering from CF. Note: Your answer should indicate the most appropriate cells taken from the patient for conversion to iPS cells and the genes that need to be expressed or repaired.

Induced pluripotent stem cells are a type of cells that can self renew by dividing and developinto th eprimary germ cells of the early embryo. It can be generated directly from a somatic cell. They can give rise to any type of cell in our body like the heart, liver, neurons or pancreas. They represent a single source of cells that can be used to replace anothe organ or cells that have bbeen damaged or lost due to some disease condition. These IPS cells can be derived directly from from adult tissues making it easier to produce and it an provide us with transplants without any risk of immune rejection.

To treat Cystic fibrosis, IPS cells are used to create lung epithelium cells. These epithelium cells form the tissue that line the airways and is the place where the CF affects the lung. Epithelial cells of the lung is the place where CF affects and causes irreversible lung disease and respiratory failure.

IPS cells are cells like fibroblasts. These are collected from the CF patients. They can be repaired with CFTR and reprogrammed to resemble embryonic stem cells (ESC) into fully differentiated cells characteristic of the proximal and distal airways. ESC and IPS cells have identical genes when they are developed from the same donor cells.

These generated epithelial cells then are grown. This contains the delta-508 mutation and G551D mutation which are genes that are mainly responsible in causing CF. Creating IPS cells that contain the entire genome of a Cystic fibrosis patient and direct them to become lung progenitor cells which develop into epithelium. Thus, IPS cells can provide use with a personlaized new tissue to replace the diseased tissue.

Cystic fibrosis (CF) is a genetic disorder that affects mostly the lungs, but also the pancreas, liver, kidneys, and intestine. CF is inherited in an autosomal recessive manner with simple Mendelian inheritance. It is caused by the presence of mutations in the gene for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. A normal couple intends to have children but consult a genetic counselor because the man has a sister with CF and the woman has a brother with CF....

Cystic fibrosis (CF) is an inherited disorder that causes severe damage to the lungs, the digestive system and other organs within the body. CF affects cells that produce thin and slippery mucus and cause the secretions to become sticky and thick. CF is caused by a deletion mutation on chromosome 7. In order for a child to have cystic fibrosis they must inherit a defective gene from each of his/her parents. Rob and Jane have four children in this order:...

Cystic fibrosis (CF) is caused by a genetic mutation resulting in defective proteins in secretory cells, mainly in the epithelial lining of the respiratory tract. The one in every 2,000 Caucasian babies who has the disease is homozygous for the recessive mutant. Although medical treatment is becoming more effective, in the past, most children with CF died before their teens. About 20 Caucasian in 2,000 are carriers of the trait, having one mutant and one normal allele, but they do...

Cystic fibrosis is genetic disease caused by mutations in the CFTR gene. The consequence of this is production of an abnormal transmembrane protein that is responsible for producing sweat, mucus, and digestive fluids. Explain in depth the correlation between the defective gene and the abnormal protein that is produced. Be sure to mention the process involved in protein production, whether or not those process(s) have occurred, and their end products. Provide details in your explanation and support your answer with...

Choose one disease/condition that affects the respiratory system. Some examples include: cystic fibrosis, asthma, pneumonia, emphysema, lung cancer, mesothelioma, and black lung disease. Research the disease/condition that you have chosen. In your discussion post, identify the disease or condition you have chosen. Then give background information on what the disease is and what causes it. Next talk about the common symptoms. Then indicate how the condition is diagnosed (tests, procedures, etc). Next talk about treatment options and the overall prognosis...

J.R., a 13-year-old with cystic fibrosis (CF), is being seen in the outpatient clinic for a biannual evaluation. J.R. lives at home with his parents and 7-year-old sister, C.R., who also has CF. J.R. reports that he “doesn't feel good,” explaining that he has missed the last week of school, doesn't have any energy, is coughing more, and is having “a hard time breathing.” J.R. is admitted to the hospital for a suspected respiratory infection and CF exacerbation. His mother...
