Spinal cord injury research different types of cells. The hope is that stem cells transplanted into an injured area of the spinal cord will allow neuroregeneration. Types of cells being researched for use in SCI include embryonic stem cells, neural stem cells, mesenchymal stem cells, olfactory ensheathing cells, Schwann cells, activated macrophages, and induced pluripotent stem cells. When stem cells are injected in the area of damage in the spinal cord, they secrete neurotrophic factors, and these factors help neurons and blood vessels to grow, thus helping repair the damage. It is also necessary to recreate an environment in which stem cells will grow.
Collaborative human interpreter Collaborative human interpreter The collaborative human interpreter (CHI) is a proposed software interface for human-based computation (first proposed as a programming language on the blog Google Blogoscoped, but implementable via an API in virtually any programming language) specially designed for collecting and making use of human intelligence in a computer program. One typical usage is implementing impossible-to-automate functions. For example, it is currently difficult for a computer to differentiate between images of men, women and non-humans. However, this is easy for people. A programmer using CHI could write a code fragment along these lines: Code for the function codice_1 can
