we explain how we clone egg cells to create embryonic stem cells in our lab at Children's Hospital Boston. Unless otherwise noted, images show mouse cells.—Kitai Kim & Willy Lensch Drs.

High-throughput nanowell-based image-verified cloning technology (HT-NIC) is a new method allowing the fast generation of clonal pharmaceutical production cell lines. Clones are generated in just one ...

The derivation of primate embryonic stem cells by nuclear transfer marks an advance toward human therapeutic cloning ... The work with Xenopus laevis a few years later obtained normal larvae ...
