3. Cell Differentiation and Specialization

Specialized cells

Cells that can perform a specific function

Stem Cells

Undifferentiated or partially differentiated cells that can develop into different types of cells around the body

Potency

A cells ability to differentiate into other cells

Totipotency

ability to give rise to any type of cell

Pluripotency

Ability to give rise to many types of cells

undifferentiated cell

cells such as stem cells that can become any cell

differentiated cell

cells that already have developed into a certain type of cell with a specific function and role

embryonic stem cells

these stem cells are totipotent and are found in developing embryos. they can develop into any type of cell

adult stem cells

undifferentiated cells found among differentiated cells in a tissue or organ

stem cell therapy

using stem cells to regenerate or treat the human body

how are stem cells used in drug development

Stem cells are used in drug development through the use of iPS cells. Through this, scientists can reprogram these cells to mimic cancer cells, allowing them to test various anticancer drugs on them.

does stem cell therapy currently work

no, most stem cell therapy is still at the theoretical stage rather than the commercial stage

ethical issues with stem cell research

1. the use of human embryos in medical research

2. usage of human biological materials

3. the potential for tumour development
