The future of stem cells: possibilities and dangers | Yekaterina Kazantseva | TEDxLasnamäe


Hello

let’s imagine

imagine

your tree which

stretches towards the sky from him

branch off on it

grow leaves

flowers appear

fruit is tied up in

windy branch day

can break off

in autumn the leaves turn yellow

and fall however

the trunk of a tree is

force to grow further and

be a vital basis

for the growth of

plants in our

the body also has

so powerful

internal reserve

these are stem cells

and stem cells

all

diversity of our

cell types and

organs like bones

skin brain in our

body stem

cells are also

powerful basis for his

recovery and

regeneration in 1999

Journal Union put

discovery of stem

cells to the third

place in importance in

biology after

discovery of a double

spiral dna single

project of man

why am i today

decided with you

talk about

stem cells

the fact is that they

laid the foundation for

new industries

medicine

regenerative

medicine or

cell therapy that

does the stem

cells

unique

there are actually two

quite simple on

first view of the fact

that they may not

Limited to share and

become practically

any of the 220 cells

our body

in principle

there are two types

embryonic cells

it is embryonic

and tissue

embryonic

stem cells

are formed in

result

fertilization and

division to the fifth and

the sixth day and of them

all

manifold

cell types and

fabrics of our

the first

study

Related

embryonic

stem cells

inevitably caused

embryo destruction

it is not surprising that they

attracted such

Attention

mass media

public and called

hot discussions they

put such

issues raised such

questions like that are

life for what day

embryo development

you can call it

live is comparable

destruction of the embryo

for salvation

human life

not

and without

religious

convictions

it is surprising that on

political level

at the level

funding

research

embryonic

stem cells

some countries

are prohibited in our

country

Scientific research

embryonic

stem cells

allowed

but not allowed

their use in

medical purposes

real technologies

modern

technology is no longer

connected with

damage

human

embryo

part of scientists

use cells

which remained

as a result of

extracorporeal

in vitro fertilization and

in any case, these

cells subject

undergo

disposal up to

now

heated debates

expediency of their

use in

medicine to others

cells

stem cells

refers to cells

which are in

our adult with you

organism

they can be found in

amniotic

fluid in the blood in

spinal fluid

brain in the skin and even in

fat represent

our fat contains

great amount

stem cells

which

necessary

come to our rescue

but in our

body stem

cells are located

frozen

condition and they

begin to

activate and

share and

specialize

Only when

admission

of certain

signals from outside it

can be either

illness or

tissue damage

of course, tissue

stem cells are already

not by that much

effective and

multifunctional

as embryonic

stem cells are so

stem cells

isolated from blood

any of the

blood cells but not

not

neurons stem

cells isolated from

fat can be

programmed

and become cells

cells of cartilage bone

but naturally fat

all photos

made in the laboratory

were made in our

laboratory and

scientists know how

use

and sent in advance

program

stem cells in

those directions

which we want

creating

certain conditions

processing medium

cells defined

factors we can

purposefully

to direct their side

muscular nervous or

bone tissue

a few years ago

a group of scientists from

Holland

using stem

cage cells for three

months have earned 100

kilogram of muscle

practically

have created

synthetic

hamburger in 2012

shinya Yamanaka and sir

john gordon received

Nobel Prize for

physiology and medicine

their discovery was

truly

revolutionary

managed

from an already mature

specialized

skin cells get

stem cell

that is, they are in

laboratory

conditions have shown that

any of our cells

can be returned

its past

they are practically

created a car

time on the cellular

level of

finally we are with you

got to

regenerative

medicine in our

modern time

cellular therapy is already

proved to be

exclusively

effective for

treatment of such

diseases as

leukemia trauma

spinal cord

retinal diseases

eyes

she is active

is used

for the treatment of

severe diseases

neurodegenerative

diseases as

Parkinson’s disease and

Alzheimer’s

like all new

modern

technologies

great attention

worth paying

understanding of all

mechanisms that

stand behind processes

regeneration and

early stages

research and

cell

therapy did not happen

without incident I will cite

here you are alone

funny event in 2009

year elderly

American

turned to the clinic

plastic

surgery with a request

rejuvenate

she was offered a new

fashion technology

rejuvenation with sexual

cells cells

separated from it

fat she killed immediately

two birds with one stone

in spite of the truth it

cost and 20,000 dollars

in the process there until pax

shares are allocated

stem cells were

injected into her skin

Special attention

giving the skin around

eye after procedure

American

returned home

that the effect of rejuvenation

waiting for effect

rejuvenation however

after some time

she began to feel

discomfort in the right

eye and at times

heard some

snapping looks like

as like a tooth

castanets which

she was very annoyed and she

could not understand what

she happens

turned to the clinic

and during a long

operations from its

upper eyelid and

cloth arrives

adjacent to

retina to

Fortunately, without large

implications for

patients were

isolated two

education is very

similar to

networks when they become

analyze

the cause of such

effect was that

together with stem

cells to the patient

was introduced

filler which

already more than twenty

five years

it was safe

used in

cosmetology for

reduce

the number of wrinkles

main component

this filler was

hydroxyapatite

calcium substance

which is in the cellular

therapy in cell

biology

are used to

that

and stem cells

get a bone to

Unfortunately this fact

slipped away from

medical attention but

let’s not

think about incidents

and we will think more

positive stem

cells are much

more serious can

be what

nanotechnologies and

silver particles

therefore modern

they are not

used here without

verification of this

the moment is 5900 45

clinical

tests are key

word that

stem cell

cell

at this stage

research

try to verify

how much is therapy

effective and

is safe as well

there is a process

highlighting

stem cells

suppose from the fat in

walls of the laboratory

first of all the patient

enters the clinic

where he is in the process

liposuction

fat is removed from

someone superfluous from whom

it is not very superfluous

this fat comes in

where with

special

enzymes are separated

cells of tissues from

friend with them

produced

manipulation

then centrifuged

these cells

sow

in a special environment and

build on

there are stem cells

such a unique

property they are capable of

attract

adhere to plastic

so these

cells are separated from

all other cells

they are built up and their

can be used

as directed

or a long time

store at very

low temperatures

liquid nitrogen I like

most scientists in

the world

I believe that the stem

therapy

a great future and

it can cure

incurable to this day

pores of disease and

reduce suffering

people on the data on

this moment

research and

application of this

therapy can be said

that yes we do not know yet

long-term collateral

effects of this therapy

we see that she is not

is so effective

since at this

stage we use

our tissue

stem cells

some opponents

such technology

fear that she

can lead to

cloning of people and

on a par with the nuclear

research

used in

inhumane purposes

however , cell

of therapy

a great future and

potential that we

still can not even

anticipate

I want to upset you

not only does

electronics but also we with

you with age

and aging of the body

number of stem

cells in the body

decreases

their

quality and

efficiency

we are exposed

influence

ultraviolet

radiation

mutagens from food

air we with you

sick and all this

doubtless

affects the

quality of our

stem cells

very often trunk

to come in

therapy can

needed in

emergency cases

such as

multiple burns

or ischemic

attack however

operating time

therapeutic

number of canteens

requires

long time

quite obvious

is becoming

need in

creation of banks

stem cells this

The project will soon be

launched and we have

estonia now

there comes a moment

when you should

feel

pride from the fact that

we live with you in

our country

the fact is that

cell therapy and

stem cells are

not far from the space

us in our country

are also underway

research

of stem cells in 2013

in Tallinn was

is open

specialized

clean laboratory

which focuses on

cell production

for medical needs

and our Estonian

doctors are already quietly

begins

use this

technology for their

goals I will give here

you have two examples from their

practice first

clinic case

addressed the elderly

patient with diabetes 2

the extent of which

tormented for two

years old wound

at his feet

invited

a course of treatment

stem cells

and after six months

the wound healed and

stopped worrying

patient 2 cases

the young man got

in an accident on a motorcycle

he had a strong

damaged damaged

a bone to him

threatened amputation

extremities doctors

also applied

stem cells

are isolated from fat and

the man stayed with

with his foot

and completely

able to work

this very moment

it is difficult to argue that

we are waiting for in the future and

what horizons and

cell border

therapy, but let’s

dream and

imagine that we

can wait say

in 20 years with our

birth

our stem cells

isolated from the placenta

will be placed in the bank

stem cells

that when

the need

come to us on

help

our stem cells

will recreate

our bodies with you

organs with 3d

printer

our cells will be

programmed

so that

will be able to recreate

change patients

tissues and organs

and you would like to revitalize

species of animals

We have already given our

lands

and you would like

try out

hamburgers meat

which is grown in

laboratory and never

was not alive

but would you like to live in

society where part

people are not alive

born and cloned

what boundaries and

stem therapy and

what are the

We are not currently

we can respond to these

and other issues

just wait and

see what us

Waits ahead

but I am sincerely

I believe that the cell

of therapy

a great future and

she is able

prolong people’s lives

and get rid of

most diseases

Thank you
