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.
