| 1. | The enzyme was introduced into the pig chromosome by pronuclear microinjection.
|
| 2. | Using microinjection methods, the approach was slow and inefficient.
|
| 3. | In microinjection, DNA is injected into the pronucleii of fertilized oocytes.
|
| 4. | The team choose to combine two approaches microinjection and embryonic stem cells.
|
| 5. | Most of the very first transmutations were performed by microinjection of DNA directly into cells.
|
| 6. | Such microinjection experiments allow highly specific and selective cell manipulations superior to gross ablation experiments.
|
| 7. | He contributed to the world's first microinjection baby via human ampullary coculture in 1991.
|
| 8. | The axons of lamprey are particularly large and allow for microinjection of substances for experimental manipulation.
|
| 9. | Paramount among these is the robustness of early embryos and their amenability to microinjection and microsurgery.
|
| 10. | The large size of embryos and amenability to microinjection also makes them extremely well suited to microarray approaches.
