STEM Cells Ultimate Quiz: Trivia!

Stem Cells are extracted from the mother 6 days after fertilization, during the blastocyst stage of development. At this point, the cells have yet to attatch to the uterus and have to go through 19 other steps before fetal development begins.

Stem cells are used for replacing diseased cells in sick patients and growing into a new organ that a patient needs. These cells have the ability to differentiate into different cell types and can be used in regenerative medicine to treat various diseases and injuries. They hold great potential for repairing and replacing damaged tissues and organs in the human body. The option "Only A and B" correctly identifies the uses of stem cells in medical applications, excluding the unrelated option of making a clone and the all-encompassing option of "All of the above."

The word "stem" has nothing to do with plant stems. Also, refer to the explanation for question 1 to see why answer choice C is incorrect.

Though many of us think of cloning as human replication, cloning in the scientific world means cell division. Cell division is when cells replicate, and occurs on a daily basis in all organisms.

Somatic cells are non-sex cells, meaning they are not involved in sexual reproduction. Examples of somatic cells include skin cells, muscle cells, and nerve cells. These cells make up the majority of the body and perform various functions necessary for the organism's survival and growth. In contrast, sperm cells and egg cells are involved in sexual reproduction and are not considered somatic cells.

There are three known types of stem cells: Embryonic Stem Cells, Adult Stem Cells, and Umbilical cord Stem Cells.

Stem cells are cells that have the unique ability to develop into various types of cells in the body. They can become any type of cell (blood, muscle, skin cells), renew themselves continuously, and can differentiate into different cell types (for example, a blood cell can transform into a neuron). Therefore, all the options provided accurately describe stem cells.

Definition from http://www.kumc.edu/stemcell/glossary.html: Stem cells that have been growing in cell culture for six or more months without becoming specialized and appear genetically normal.

Do not let the term "adult" confuse you. Mature tissue is found in any human after birth. Tissues are only not "adult" while still in development, that is, in the embryonic stage.

The United States currently has 65 stem cell lines.
