Embryonic stem cells are pluripotent. An embryo begins as a single, fertilised egg that divides to form a blastocyst. The blastocyst is made up of embryonic stem cells, which can differentiate into all cells, such as brain, heart, liver and lung cells.
Explore the intriguing differences between embryonic and adult stem cells and their revolutionary medical potential.
Human embryonic stem cells differentiated into dopaminergic neurons, which are the ones that degenerate in Parkinson's disease. Working with these cells in a lab dish provides a way to study the origins and possible treatments for Parkinson's disease. This photo was taken by Jeannie Liu in the lab of Jan Nolta at the University of California, Davis.
A team of researchers from Scotland has used a novel 3D printing technique to arrange human embryonic stem cells (hESCs) for the very first time.

Researchers in the UK have derived very early stage stem cell lines – called 'naive' pluripotent stem cells – from human embryos for the very first time.
An adult stem cell is thought to be an undifferentiated cell, found among differentiated cells in a tissue or organ. The adult stem cell can renew itself an...
The development and evolution of eyes is ancient and difficult problem in biology. Darwin postulated a prototype eye which can evolve under natural selection. Neo-Darwinists, based in morphological criteria, have postulated a polyphyletic origin that has evolved independently in the various animal phyla. Molecular phylogenetic analyses and developmental genetic experiments, cast serious doubts on both theories. The study of the development of the eye in the amphibian embryo has been a formidable tool research to experimental embryology and evolutionary biology as early as 1901. The embryonic induction, the interactions between different embryonic tissues (organizers); and the role of genes, were conceived as result of reciprocal transplantation experiments.
