Stem cell means that all the tissues of the whole body are formed from the cells of the embryo. The primary cells of the zygote and embryo are called stem cells. The unicellular zygote divides repeatedly to form a multicellular embryo. Embryo cells divide repeatedly to form organs such as brain, heart, lungs, liver, kidney, stomach, eyes, etc. Complete human body is formed by these organs. In the 19th century, the primary cells of the zygote and embryo were named stem cells.
Importance of stem cells
- New cells are produced from stem cells to regenerate damaged organs or tissues.
- Stem cells are used to repair organs that cannot function properly.
- Can differentiate in different ways to form different types of cells and tissues.
- Embryonic stem cells can be used to make new tissue.
- Organs like heart, kidney, liver, lung etc. can be produced and used.
- Can make meatballs for human consumption. So there will be no need to keep cows, buffaloes, sheep, goats, poultry etc. The United States has recently allowed the marketing of laboratory-grown chicken meat.
- Organs like bone marrow, skin, liver etc. have some stem cells. They have the potential for regeneration and repair.
