Stem Cells
Pediatric Pandemic:
Jescelia Mitchell, Sophia Nei, Diane Quang, Nicholas Zenquis

Embryonic Stem cells have been a large part of today’s science news.
◦ There’s talk about what stem cells can do for the future of human life.
◦ Advancement of human health
◦ There’s also been talk against the use of stem cells because some believe it
is unethical

Our group choose the question: How is it possible to obtain
embryonic stem cells and is it also possible to obtain adult stem
cells? because we did not know much on the subject, so the question
seemed very appealing and we wanted to learn more about it.
Introduction
Stem Cells are very important
cells in the development of a
human being. They have an
amazing ability to develop into
multiple different cell types and
they can remain, without a
specific function, in the human
body.
These cells can also
regenerate and repair organs at
an unlimited rate. The fact that
these cells can develop into
different cells is over great
importance because usually cells
are defined into certain job and
these are not.
What are Stem Cells?
Embryonic Stem Cell
Adult Stem Cell

Embryonic stem cells are
pluripotent cells. Which means
they can differentiate themselves
into three main germ layers:
◦ Ectoderm
◦ Mesoderm
◦ Endoderm
Embryonic cells come from the
inner mass of the blastocyst at
about 4-5 days after being
fertilized.
 At this age these cells are
extracted from the embryo using
in-vitro, which in fact kills the
embryo.

◦ This raises the question of the
process being ethical or not.
What are embryonic cells?
How are they obtained?

Yes! Adult stem cells can
be obtained.
◦ They can be found and
extracted from tissues of
organs and from bone marrow.

Adult stem cells are
multipotent cells though.
◦ This means they cannot renew
themselves as much as
embryonic cells can and are
limited in the type of cell they
can become, unlike embryonic
stem cells.
Is it possible to obtain adult
stem cells?
Have they tested these cells on humans or
animals?
 With the use of the cells what potential do
humans have of living a longer, healthier
life?
 With the advances in science of today’s
world there are consequences, what are the
projected consequences of this research?
 Do these consequences stretch further than
ethics?
