A picture gallery of stem cells.

1. Stem Cells Under the Microscope: A Picture Gallery
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.

stem cells differentiate into cardiac myocytes.

11. Important Embryonic Stem Cell
Research Milestones
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
