Epithelial Cardiac Myocytic Mitochondrial( Epithelial, Cardiac, Myocytic, Mitochondrial ) cells form a lining muscle gland neuron( lining, muscle, gland, neuron ) in many different organs and structures. The cells are joined together by tight junctions light junctions wide junctions permeable junctions( tight junctions, light junctions, wide junctions, permeable junctions ) which facilitates communication programmed cell death protein synthesis mitosis( communication, programmed cell death, protein synthesis, mitosis ) and keeps them tightly packed loosely touching mobile unspecialised( tightly packed, loosely touching, mobile, unspecialised ). Some have cilia, for example in the respiratory tract bone tissue the cornea nerve cells( the respiratory tract, bone tissue, the cornea, nerve cells ), which help waft mucus lipids hormones( mucus, lipids, hormones ) and foreign particles up to the throat. Others have microvilli, for example in the digestive tract the liver glial cells blood vessel endothelium( the digestive tract, the liver, glial cells, blood vessel endothelium ), to increase decrease( increase, decrease ) surface area and increase rate of absorption digestion cell division( absorption, digestion, cell division ). These type of cell tend to have short long( short, long ) cell life cycles.

Stem cells Erythrocytes Cardiac cells Genetically engineered mice( Stem cells, Erythrocytes, Cardiac cells, Genetically engineered mice ) are a hot topic in scientific research because of their wide range of potential applications, including cancer therapy, treatment of immune diseases, and regeneration of damaged tissues and organs. If stem cells can become nerve blood muscle kidney( nerve, blood, muscle, kidney ) cells, they can be used to treat Alzheimer's and Parkinson's diseases. Growing organs from a patient's own stem cells avoids the need for immunosuppressive therapy long transplant surgery patient-specific aftercare( immunosuppressive therapy, long transplant surgery, patient-specific aftercare ). This is called regenerative systemic organ specialised( regenerative, systemic, organ, specialised ) medicine. They're also key in understanding aspects of developmental plant cognitive mobile( developmental, plant, cognitive, mobile ) biology. Finally, stem cells can be used to grow organs on which to safely test new therapeutic drugs.
