Coelomocytes and post-traumatic response in the common sea star
Scientists are using sea stars in a experiment to test what their nervous systems capability is and which species have a developed immune system when amputations take place. Coelomocytes are recognized as the main cellular component of the echinoderm immune system. They are the first line of defense and their number and type can vary dramatically during infections or following injury. Sea stars have been used as a model system to study the regeneration process after autotomy or predation. In terms of trauma and post- traumatic stress periods, the arm amputation and repair phase involved in the first 24 hours post- amputation, mimicked a natural predation period. There was a increase in the total umber of freely circulating coelomocytes was observed 6 hours post- amputation. I picked this article because I was interested in how the regeneration process of a sea stars limbs worked. I felt that the study presented was well thought out and organized. Also, that is clearly demonstrated how the regeneration process works in a sea stars body.

ReplyDeleteThis article is very interesting. The multiple tests that the sea stars are used for is amazing and the choice to use sea stars instead of something else is also interesting. Learning the process of regeneration in their limbs and also demonstrating how this process works in a sea stars body made this summary more clear and gave a better understanding to how the sea stars help demonstrate this experiment so well.
