As a means of producing large quantities of cells needed for the regeneration of human tissues, medical scientists are utilizing:
a. somatic cell nuclear transfer, plasmids, and gene splicing.
b. gene splicing, polymerase chain reaction, and transgenic organisms.
c. embryonic stem cells and induced pluripotent stem cells.
d. somatic cell nuclear transfer, embryonic stem cells, and induced pluripotent stem cells.
e. gene splicing, cloned cells, and transgenic organisms.
Adv.
As a means of producing large quantities of cells needed for the regeneration of human tissues, medical scientists are utilizing embryonic stem cells and induced pluripotent stem cells. Stem cells are cells, which has the ability to develop into numerous cells of its class and also a particular variety of specialized cells. The human body produces different types of stem cells in different phases of life.
The stem cells, which occur during the embryonic development in humans, are called embryonic stem cells. During fertilization, the nucleus of the sperm fuses with the nucleus of the egg. The fertilized egg is subjected to cell division. The blastocyst stage occurs during the fifth day of cell division. The blastocyst encloses the placenta and the inner cell mass.
The inner cell mass consists of embryonic stem cells, which has the ability to develop into any type of cell in the human body. Induced pluripotent stem cells are developed by inserting four developmental genes into adult skin cells. They have the ability to develop into any type of cells in the human body. Thus, embryonic stem cells and induced pluripotent stem cells are used by medical scientists for regeneration of human tissues.
Hence, the correct option is (c) embryonic stem cells and induced pluripotent stem cells.
