I was really excited to find out there was a website available to post questions on and get answers from real scientists! I was a little disappointed that I posted my question over a week and a half ago and never got a reply. My question was as follows: If cells are constantly performing mitosis to repair dead or damaged tissue, what causes scar tissue to build up & why do some cuts repair themselves leaving no scar behind, while other cuts leave scars?
Since I didn't get an answer form the website, I went to my own real scientist for an answer; my supervisor! I told him the situation and presented him with my question. He explained to me that when a cut is fairly superficial, the cells are still in close enough contact with one another to communicate proper healing and are able to repair the tissue so that it looks as if a cut ever happened. However, if a cut is very deep and/or wide, the cells in the surrounding area are not close enough to be able to communicate and you are left with scar tissue. Makes sense to me!
I'm not sure I would be willing to use this website since I never got a response. I'll be curious to see if others heard anything back. I love the idea of this site and would like to use something similar because I get questions regularly from my students that I can't fully explain and I could post their question immediately and hope for a response.
