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...
Video microscopy demonstrating how sperm from an infertile male can be injected into a female egg.
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?
