Summary of "Cell Biology and Biotechnology, Lecture 1 | Class 10 SSC | Embryonic stem cells and adult stem cells"

Summary of Lecture on Embryonic and Adult Stem Cells

Main Ideas and Concepts:

Introduction to Cell Biology:
Cells are the fundamental units of life, forming the basis of all living organisms, including plants, animals, and microorganisms. The study of cells, their structure, types, and functions is known as Cell Biology.
Types of Cells:
- Prokaryotic Cells: Simple cells without a nucleus (e.g., bacteria).
- Eukaryotic Cells: Complex cells with a nucleus (e.g., plant and animal cells).
Stem Cells:
Stem Cells are unique cells capable of developing into various cell types in the body. There are two main types of Stem Cells:
- Embryonic Stem Cells: Derived from embryos and have the potential to develop into any cell type (pluripotent).
- Adult Stem Cells: Found in various tissues in adults (e.g., bone marrow, fat) and are responsible for tissue repair and regeneration.
Cellular Differentiation:
The process by which Stem Cells develop into specialized cells (e.g., neurons, muscle cells) is called Cellular Differentiation.
Fertilization and Embryonic Development:
Fertilization occurs when sperm and egg cells combine, forming a zygote that divides and develops into an embryo. The embryo undergoes various stages of development, eventually leading to the formation of different tissues and organs.
Applications of Stem Cells:
Stem Cells can be used in Regenerative Medicine, such as healing injuries and repairing damaged tissues. Research in Stem Cell Therapy holds promise for treating various diseases.
Stem Cell Preservation:
Stem Cells can be collected from embryos, bone marrow, and umbilical cord blood for future medical use. Preservation involves storing Stem Cells in liquid nitrogen at very low temperatures.
