Tag: watching cells divide is really relaxing

I was reviewing wound healing by watching youtube lectures on it and I stumbled across this video of fibroblasts doing their thaaaang. Cool beans. I love it! I’ve never seen these things in action before! 

So, in a very big nutshell, if you’re not sure what fibroblasts are, they build collagen fibers. Collagen fibers are incredibly strong connective fibers that hold things together. So when you cut yourself, a lot of things happen to repair it as quickly and efficiently as possible – fibroblasts rushing to the scene to build a new matrix to help repair the damaged tissue is one of those things. They also help pull the wound together, making it easier for the cells to grow back together.
