● It also known as Cell Differentiation.● It a normal process by which a less specialized
cell develops or matures to possess a more distinct form and functions
● The key point to differentiation is ○ Put cells in a different environment and get a
different outcome.
What is Differentiated Cells?

● It a undifferentiated biological cells, that can differentiate into specialized cells and can be divide (through mitosis) to produce more stem cells.
● They are usually found in multicellular organisms.
● There are two types of stem cells:○ Embryonic stem cells, which are isolated from
the inner cell mass of blastocysts○ Adult stem cells, which are found in various
tissues.

● Embryonic stem cells are pluripotent● They are capable of differentiating into
virtually any tissue type○ Replace or repair damaged tissues and organs○ Correct inherited diseases
Embryonic Stem Cell
➢ However, many embryonic stem-cell research is immoral
➢ Because in the process of collecting the stem cells➢ The embryonic stem cells is destroyed

The Studies from Two U.S Researcher
Catherine Verfaillie Ronald McKay
![Page 7: Differentiated Cells By: Tu Huynh. ●It also known as Cell Differentiation. ●It a normal process by which a less specialized cell develops or matures to](https://reader035.vdocument.in/reader035/viewer/2022062304/56649e3f5503460f94b2f508/html5/thumbnails/7.jpg)
● Catherine Verfaillie ○ found that stem cells
isolated from the marrow of adult mice and rats appear to be nearly as long-lived and versatile as embryonic stem cells
○ these cells called multipotent adult progenitor cells which are very similar to cells that she identify in human marrow
The First Study● Ronald McKay
○ transformed mouse embryonic stem cells into dopamine-producing neurons
○ transplanted a disease into the mouse
○ its established functioning connections with surrounding brain cells, began releasing dopamine, and reduced signs of the disease
The Second Study

● Opponent○ Can be safely harvested from a consenting adult○ Offer just as much promise for research and new
therapies● Proponent
○ Not useful, because they are already partially differentiated
○ They do not grow as well in culture○ They age rapidly and cannot differentiate into as
many different tissue types
