Stem cells are how we all begin: undifferentiated cells that go on to develop into any of the more than 200 types of cell the adult human body holds. (Courtesy: New York Times)

We have read about stem cell research in various disease fields. Here is a gallery of stem cells sourced from various published papers.

Spontaneous embryonic stem cell differentiation in mouse cells. The bright green cells show that some embryonic stem cells differentiate into cardiac myocytes.

Important Embryonic Stem Cell Research Milestones

• 1978- Stem cells were discovered in human cord blood• 1981- First in vitro stem cell line developed from mice• 1988- Embryonic stem cell lines were created from 

hamsters• 1995- First embryonic stem cell line derived from a primate• 1997- Cloned lamb from stem cell and leukemia origin 

found as haematopoietic stem cell, which could indicate potential proof of cancer stem cells
