Why thymus tissue are used in DNA extraction?
Thymus tissue is rich in lymphocytes, which contain a lot of DNA. This makes it a good source for extracting DNA for analysis. Additionally, thymus tissue is easily accessible in some animal models.
Which lymphoid organ does not contain reticular connective tissue?
The thymus is a lymphoid organ that does not contain reticular connective tissue. Instead, it is composed of epithelial cells and lymphocytes. This organ plays a crucial role in T cell maturation and development.
Stem cells responsible for the process of lymphopoiesis are located where?
Stem cells responsible for lymphopoiesis are primarily located in the bone marrow. As they differentiate, lymphoid progenitor cells move to the thymus (in the case of T lymphocytes) or remain in the bone marrow (in the case of B lymphocytes) to further mature into functional lymphocytes.
What is a collective label for t and b immune cells?
Lymphocytes.
Are lymphocytes phagocytic?
No, lymphocytes are not phagocytic cells. They are a type of white blood cell that plays a key role in the immune response by recognizing and destroying foreign invaders such as viruses and bacteria. Phagocytosis, on the other hand, is the process by which certain types of immune cells engulf and digest pathogens.
