Question

Describe the process used for harvesting embryonic stem cells

Answer 1

The process of harvesting embryonic stem cells involves the creation of cloned human embryos and the isolation of stem cells at the blastocyst stage.

Step-by-step explanation:

Harvesting embryonic stem cells involves several steps:

1. The first step is the creation of cloned human embryos by introducing the DNA from an adult human into a human egg cell.
2. The embryos are then stimulated to divide and develop into the blastocyst stage. These cells are called embryonic stem cells because they have the capacity to develop into many different kinds of cells.
3. The blastocysts can be harvested and the stem cells can be isolated for further use in research or therapeutic applications.

Overall, the process of harvesting embryonic stem cells involves the creation of cloned human embryos and the isolation of stem cells at the blastocyst stage.

Answer 2

Answer: Altered Nuclear Transfer New method

the embryos are grown into cell clusters.

the inner mass of the embryo is rich in embryonic stem cells.

the inner mass is therefore harvested , and the embryo discarded.

somatic Cell Nuclear Transfer (SCNT)-Old method.

somatic cells are grown in the laboratory.

donor cells with the nucleus removed are provided.

the somatic cells nucleus are removed, and planted into the donor cells.

the donor cells undergo pseudo fertilization, and the embryo formed.

the inner mass cells is harvested for the embryonic cells with the death of embryo,
