Somatic cell nuclear transfer (SCNT) is a technique for cloning. The nucleus is removed from a healthy egg. This egg becomes the host for a nucleus that is transplanted from another cell, such as a skin cell. The resulting embryo can be used to generate embryonic stem cells with a genetic match...
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.
Dr. Melton describes the process used to extract DNA from a cell and to analyze it on a gene chip.
An overview of embryonic development, the progressive differentiation of cells, and properties of embryonic stem cells.
In cloning, a cell's genetic machinery is reprogrammed. Can we similarly coax stem cells to become specific cell types?
