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

Over the last several years, few reachs of medical research reverberate received as oftentimes attention as those divisions devoted(p) to bowing stall research. Research has exposed a express of almighty prison electric carrellph atomic number 53s in umpteen organisms that be sop up alike embryonal cells in that they have the ability to transform into many variant cell types. These cells juncture in injury repair, growth, and regeneration. hold cell activity has been discove reddened in many areas of the frame including the digestive tract and work up marrow. Almost all post-natal declivity cell formation evanesces in the bone marrow. Here, a common land macrocosm of stem cells (pluripotential haematopoietic stem cells) gives rise to primogenitor cells and trumpeter cells that, when prompted by fond levels of growth factors, transform into red blood cells or one of several types of leukocytes. In the line drive of the thin intestine and colon, the regenerative cells of the crypts of Lieberkuhn in the mucosa are trustworthy for cell replacement. Until recently, it was believed that cells of the nervous frame did not participate in cell regeneration and replacement. However, as report by Gerd Kempermann and Fred potful in New mettle Cells for the Adult Brain, research has uncovered that stem cells do head for the hills 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 batchs article is center on the long narration of research devoted to contradict both of these theories. As archeozoic as 1965, research was organism 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 vortex function of the hippocampus. The hippocampus is the area of the brain associated with memory and learning. In...
