Stem cells are immature, undifferentiated cells that can divide and multiply for an extended period of time, differentiating into specific types of cells and tissues.They are defined as cells that self replicate and are able to differentiate into at least two different cell types. Both criteria must be present for a cell to be called a ¿stem cell.¿ Discoveries in stem cell research presents an opportunity for scientific evidences that stem cells, whether derived from adult tissues or the earliest cellular forms hold great promise that go far beyond regenerative medicine. Recent studies have shown that Stem cells from human exfoliated deciduous teeth (SHED) have the ability to develop into various types of body tissues than other types of stem cells.Dentists are at the forefront of engaging their patients in potentially life-saving therapies derived from their own stem cells located either in deciduous or permanent teeth.

The R language is a project designed to make a free, open source language.In terms of current feature sets, given the Comprehensive R Archive Network (CRAN) library of packages, there are few statistical processes one can't get done in either R or SPSS.Both have spreadsheet-like GUI capabilities and both can interface with common relational databases. The final differentiator is cost. The basic version of R is open source, as are most of the packages in CRAN.The only cost is the bandwidth to download R and whatever packages you need. There is a commercial version of R from Revolution Analytics that's more highly tuned and has support and training included. R is software package especially suitable for data analysis and graphical representation. Functions and results of analysis are all stored as objects, allowing easy function modification and model building. R provides the language, tool, and environment in one convenient package.this work is implemented using R 2.13.1.Direct copy of this work by anyone is strictly prohibited.
