Manipulating the human embryo: cell cycle checkpoint controls

J FulkaR M Moor


Micromanipulation techniques are widely used in assisted human reproduction and it is logical to assume that successes with recent animal cloning will invariably raise the question of human cloning along with its related ethical problems. However, it is often overlooked that even in animals many complications are still associated with this technique. The purpose of our article is to highlight and discuss some of these problems in the context of the eventual use of nuclear and/or cytoplasmic transfer techniques in assisted human reproduction.

Cell Checkpoints & Regulators

Cell cycle checkpoints are a series of complex checkpoint mechanisms that detect DNA abnormalities and ensure that DNA replication and repair are complete before cell division. They are primarily regulated by cyclins, cyclin-dependent kinases, and the anaphase-promoting complex/cyclosome. Here is the latest research.
