Classroom Resource
To accompany the lecture series Potent Biology: Stem Cells, Cloning, and Regeneration.
Click & Learn
An overview and comparison of different regenerative capabilities in many different organisms.
Classroom Resource
This activity uses the planaria's property for regeneration and compares how long it takes for planaria cut in different places to regenerate a head.
Classroom Resource
A chapter list to accompany the DVD.
Video Clips
Dr. Rosenthal describes how antlers are one of the few examples of complete mammalian regeneration.
Interview
An interview with Amy Greenwood and Alice Chen, two scientists in Dr. Melton's lab.
Video Clips
Dr. Rosenthal uses a model of a heart and an artery to describe how blockages lead to heart attack and tissue damage.
Video Clips
Cell cultures derived from human embryonic stem cells can reproduce indefinitely and also differentiate into specialized cell types, including beating heart cells.
Interview
An interview with Dr. Jose Gonzales, Manager of the Laboratory Animal Resources and Knockout Mouse Facility at EMBL in Monterotondo Italy.
Interview
An interview with Olivier Mirabeau, a scientist in Dr. Rosenthal's lab.
Interview
An interview with Dr Mumna Al Banchaabouchi, researcher in the Mouse Phenotyping Core at EMBL in Monterotondo Italy.
Video Clips
A mini-documentary discussing the remarkable regenerative capabilities of the planarian, and how HHMI researcher Alejandro Sánchez Alvarado uses them to study the biology of stem cells.
Video Clips
Somatic cell nuclear transfer (SCNT) is performed looking through a microscope and using small glass pipettes to handle human eggs and to remove and transfer nuclei from one cell to another.
Video Clips
Dr. Melton describes the process used to extract DNA from a cell and to analyze it on a gene chip.
Classroom Resource
A text transcript of the 2006 Holiday Lectures on Science, Potent Biology: Stem Cells, Cloning, and Regeneration.
Lectures
An overview of embryonic development, the progressive differentiation of cells, and properties of embryonic stem cells.
Lectures
The role of stem cells in regeneration, and ongoing research to improve mammalian regeneration potency.
Lectures
In cloning, a cell's genetic machinery is reprogrammed. Can we similarly coax stem cells to become specific cell types?
Lectures
Finding factors to reverse age-related loss of cell maintenance, and some examples of stem cell therapies.
Lectures
A discussion on policies and ethical issues associated with stem cell research.
Series
Doug Melton and Nadia Rosenthal are leaders in stem cell research, working primarily with mouse and human tissue. They will discuss where embryonic and adult stem cells come from and the biology of how they supply the cells the body needs.
Animation
The zebrafish heart is similar to the human heart in many respects. But unlike the human heart, the fish heart closes wounds rapidly and then regenerates to nearly full function. Fibroblast growth factor (FGF) is an important molecule in the regeneration process.
