Transcript of Cloning

Alternative
...to therapeutic cloning with embryonic stem cells
Resume
Natural clones:
2.History of reproductive cloning
Cloning
Structure
1. How to clone?
reproductive cloning
therapeutic cloning
3.Today's procedures
and future expectations
FDA classified the consumption of
cloned products as uncritical
2. History of cloning
5. What's good and what's bad at cloning?
3. Today's procedures and future expectations
6. Resume
4. What's good and
what's bad about cloning?
= production of genetically identical descendants of plants, animals,
humans
or cells

1.How to clone?
Reproductive cloning
--> aim: cloning for
reproduction
Negative aspects:
Therapeutic cloning
-> aim: cloning of specific
cells for medical using
1. Isolation of somatic cell and egg cell
2. Removal of both nucleuses
3. Fusion
egg cell
somatic cell
4. Breeding in vitro
clone
Opportunities
heal diseases
1. Isolation of adult stem cells
Procedure:
2. Manipulation -> development as embryonic cells
Advantage:
adult stem cells can not be rejected
Risk:
mutations can occur
1994
1970
2009
1996
1901
1952
first development
of a new creature with the help of somatic cells
first tries to clone sheep
first cloned mammal Dolly the sheep was born
an animal from an extinct species
first cloning in history:
Hans Sperman cloned a salamander
scientists did additional research
on frog embryo
-> experiment failed
criticism: embryos will be destroyed
cloned species have desired characteristics
breeding of extinct or endangered animals
problems during the procedure of cloning
problems with cloned cells:
- tumors/ rejection
- no guaranteed long-term effect

4. Permissions in different countries
4. Permissions in different countries
production of "Designer Babies"
heal diseases by replicating complete organs
2004
2014
2013
cloning of human stem cells
-> fraud
extract of human embryonic stem cells
extract of pluripotent cells from a diabetic
2. History of therapeutic cloning
-> hundred of failed trials
Thank you for your attention
produce "Designer Babies"
2014
