Differentiated CellsBy: Tu Huynh

● 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.

Stem Cells

Stem Cells

● 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

● 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

Just kidding

● 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
