This document presents a picture gallery of stem cells from various published papers and research. It includes images of neural stem cells in rat brain tissue, human embryonic stem cells forming colonies in vitro and for transplantation, germ line stem cells in tissue, and hematopoietic stem cells. Captions describe the stem cell types and sources. The document also lists important milestones in embryonic stem cell research from 1981 onward, such as the first in vitro mouse stem cell line and first primate embryonic stem cell line.

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:

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

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
