Objective: To understand the therapeutic value of stem cells
About tissue stem cells
Stem cells are one of the most amazing types of cells because they can (1) make copies of themselves and (2) make specialized cells like skin cells, red blood cells or liver cells.
1. We need stem cells in our body. What would happen to you if you didn’t have stem cells?
Tissue stem cells have the potential to make several types of specialized cells, but not all. For example blood stem cells can make all the different types of cells in your blood, but they can’t make skin cells.
2. Add the following labels to the diagram:
a. specialized cells in blood; b. blood stem cell; c. make copies; d. bone marrow.
