| 21. | This explains why Glis1 expression is switched off in embryos after they have started to divide.
|
| 22. | Ultimate Genetics specializes in embryo freezing and transfer, conventional reproduction techniques widely used in the livestock industry.
|
| 23. | Somatic modification in embryos is a grey area because there is a greater likelihood of germ-line modification.
|
| 24. | The primitive ( stem ) cells are detected in embryo and their numbers increase steadily during development
|
| 25. | Growth in embryos is mostly autonomous.
|
| 26. | Members of this family play multiple roles during pattern formation in embryos of numerous vertebrate and invertebrate species.
|
| 27. | Stem cells are especially abundant in embryos, but are also found in adults and in umbilical cord blood.
|
| 28. | The latter often results in embryo abortion, presenting an ethical dilemma for many that can now be avoided.
|
| 29. | ANI-1 is required for cortical ruffling, pseudocleavage, and all contractile events that occur in embryos prior to mitosis.
|
| 30. | The researchers monitored the expression, or action, of genes that play a role in embryo and fetal development.
