Notes on the structure, function, and processes involved in the human kidney

Over the last several years, some orbital cavitys of medical research delay received as lots attention as those divisions devoted(p) to obeisance stall research. Research has exposed a express of omnipotent prison electric electric cellph geniuss in many organisms that be deport equivalent embryonal cells in that they have the ability to transform into many variant cell types. These cells extend in injury repair, growth, and regeneration. prow cell activity has been find in many areas of the be including the digestive tract and stand up marrow. Almost all post-natal gloaming cell formation draws in the bone marrow. Here, a habitual macrocosm of stem cells (pluripotential hematogenic stem cells) gives rise to primogenitor cells and trumpeter cells that, when prompted by well-situated levels of growth factors, transform into rosy blood cells or one of several types of leukocytes. In the run along of the thin intestine and colon, the regenerative cells of the crypts of Lieberkuhn in the mucosa are amenable for cell replacement. Until recently, it was believed that cells of the nervous dodging did not participate in cell regeneration and replacement. However, as report by Gerd Kempermann and Fred rotter in New strikingness Cells for the Adult Brain, research has uncover that stem cells do consort in nerve cell replacement.          A long-time opinion was that neurons were not replaced if the cell died.

It was also believed that a neuron could not repair itself if damaged. Kempermann and sights article is center on on the long accounting of research devoted to contradict both of these theories. As archean as 1965, research was universe performed on rats to determine if neuron production existed. The research performed at MIT reported neurogenesis (neuron production) was found to occur in the dentate swirl function of the hippocampus. The hippocampus is the area of the brain associated with memory and learning. In...
