Stem cell research and experimentation has been in process for well over five decades and they have been a huge medical success story because stem cells have the unique characteristics whereby they are able to divide and replicate repeatedly in addition to their being unspecialized with the ability to differentiate into specialized cell types.

The possibilities that arise with the perfecting of cell replication has caused this area of exploration to remain at the forefront of scientific research, with ongoing hope that cures and treatment of diseases as well as reparative cell therapy, tissue regeneration and pharmacological testing on cell-specific tissue will one day become viable options within the medical community. 

Traditionally, scientists have worked with both embryonic and adult stem cells. In the late 1990s, technology was created to produce human embryonic stem cells but  there has been significant ethical, moral and spiritual controversy surrounding the use of human embryonic stem cells for research. As a compromise, the NIH limited federal funding for hESC research to lines that had already been created, states and the private sector were still able to work on them without restriction. Adult stem cells can differentiate but they are typically limited to differentiation within their original tissue type, creating narrower options for their use, so some government-funded researchers believed any limitation on hESCs was impeding science. Most of the restrictions on hESC research remain in place today.

Yet the worrying over hESC may have been unwarranted, at least as far as impeding science. 293 researchers surveyed in the "Complete 2012-13 Induced Pluripotent Stem Cell Industry Report" identify induced pluripotent stem cells (iPSCs) as their core research focus. Of the 293 respondents, 181 were U.S. based and 112 were international. The survey findings reveal iPSC researcher wants and needs and technical preferences, and key factors. 

Key metrics include charts, timelines and financials for the iPSC research market; 5-Year Projection Data for 2012-2017; oreferred Species for iPSC Research.
