Juan Carlos Torres Sánchez 804-11-9230 BIOL 3095 5/18/2012 Seminar 1 on Stem Cells, Discussing the Seminar PresentationOn September 26 and 27, we had a seminar with Jessian Muñoz, a college graduatestudent fromNew Jersey Medical School. This experience has opened my mind inrelation to a new aspect of science I did not know quite well, cancer stem cells. Howcould cancer stem cells be the primary cause of brain tumors? That question was wellanswered by our seminar person of this week, Mr. Jessian Muñoz. Due to hisknowledge, we learned about brain tumors, what the starting point is,and about a newtopic, the microRNA. The microRNA was discovered in the human genome project,whichdemonstrates how science discoveries have made lots of great advances inbenefits of health care. Dysfunction in microRNA signaling is present in all cancersthat have been studied thus far.There was also the discussion about cancer stem cells (CSC). Cancer stem cells arethe of brain tumors. The problem that we had before was that with chemotherapy, thecells that were targeted were the ones around the cancer stem cells so the cancerwould normally spread again. What they are trying to do is to suppress the pathway ofthe stem cells so that stem cells will become responsive to chemo and radiotherapy.They are encountering problems with this procedure also as cancer stem cells arereappearing after therapy. Finding these cancer stem cells implies that this could bethe cure for cancer. Also, stem cells could be applied to different studies, for examplenew knowledge has been provided that giving stem cells to a person with diabetescould help regenerate their pancreatic beta cells.Jessian’slifelong goals changed during the course of his studies, he went fromwanting to be a pedriatitian to studying a PhD. This demonstrates how it doesn’tmatter how long it will takeor if I change my goals, as long as I persevere it will be all
worth it at the end. I recommendthese types of seminars to anyone who wants to bemore knowledgeable on exciting topics.
