Question Set 2

a.In what tissues are adult stem cells typically found?

b.What tissue has been most exploited for the derivation of both hematopoietic stem cells and mesenchymal stem cells?

c.What is an induced pluripotent stem cell (iPSC)?

d.Name five cell lineages that derive from mesenchymal stem cells.

e.Come up with a possible benefit for culturing cardiac muscle cells in the laboratory. In other words, how could they be used to advance science?

f.What are some of the main functions of:

Fibroblasts

Adipocytes

Chondrocytes

Myocytes

Osteocytes

Solution

2 a)-  Adult stem cells are found in this tissues typically :- brain, bone marrow, peripheral blood, blood vessels, skeletal muscle, skin

b)-Bone marrow tissue has been most exploited for derivation of the both the stem cells

c)- Induced pluripotent stem cells are a type of pluripotent stem cell that can be generated directly from adult cells.

d)- osteoblasts (bone cells), chondrocytes (cartilage cells), myocytes (muscle cells) and adipocytes (fat cells), tendon/ligaments, connective cells are the five cell lineages which are derived from mesenchymal stem cells

e)-The benefits of culturing of the cardiac muscle cells is the reusability of the cells due to their self regeneration capacity .

f)- The main functions of the fibroblasts are to synthesize the extracellular matrix and collagen. it also plays a critical role in wound healing.

adipocytes stores energy in themselves . it also acts as a cushion and insulator

Chondrocytes produce and maintain the cartillage matrix

Myocytes gives rise to the muscles in the body

Osteocytes gives rise to the bones in the body . they maintain the strength and health of the bone matrix
