Differentiated Cells By: Tu Huynh
What is Differentiated Cells? • 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.
Stem 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 Cell • 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 • 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 Ronald McKay Catherine Verfaillie
The First Study The Second Study 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 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

Just kidding THE END
Opponent and Proponent of the embryonic stem-cell research • 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

What is Differentiated Cells and what are they? • 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 function
What is the key point to differentiation? • Put cells in a different environment and get a different outcome.
What are stem cells and where are you usually found them? • 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.
