Astrocytes are the star shaped cells that are present in the brain and spinal cord. The exact constitution of astrocytes in the brain is not known and almost 20% to 40% astrocytes are present in brain.
The astrocytes acts as the blood brain barrier and involved in the process of brain scarring. Astrocytes also regulate ions concentration by propagating the calcium ion channels in response to the stimulus. Astrocytes also generate a response by the calcium dependent release of glutamate.

<em>Conclusions made from scientific research or understanding can always be challenged by anyone with new ways of observing and with different interpretations. This is the essence of the repeatability or reproducibility of scientific experiments.</em>
Scientific research must be reproducible and if the earlier conclusions or understanding is found to be somehow inadequate with overwhelming evidence, they are modified or even changed completely in order to accommodate new facts.
Hence, the emergence of new ways of observing different interpretations can lead to new/different conclusions from the same research. If the new conclusions gain enough evidence, it becomes the new theory.
