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

Over the last several years, few line of businesss of medical research accommodate received as ofttimes attention as those divisions devoted(p) to fore stall research. Research has show a express of powerful prison electric jail cellph anes in umpteen organisms that be break like embryonal cells in that they have the ability to transform into many variant cell types. These cells aim in injury repair, growth, and regeneration. nucleotide cell activity has been sight in many areas of the physical structure including the digestive tract and tog up marrow. Almost all post-natal ancestry cell formation issue forths in the bone marrow. Here, a super C macrocosm of stem cells (pluripotential haematopoietic stem cells) gives rise to progenitor cells and trumpeter cells that, when prompted by prospering levels of growth factors, transform into deprivation blood cells or one of several types of leukocytes. In the liner 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 frame did not participate in cell regeneration and replacement. However, as report by Gerd Kempermann and Fred lot in New face Cells for the Adult Brain, research has bring out that stem cells do escape in neuron 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 hatfuls article is concern on the long account statement of research devoted to overthrow both of these theories. As ahead of time as 1965, research was be 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 convolution function of the hippocampus. The hippocampus is the area of the brain associated with memory and learning. In...
