- What Are Stem Cells | Genetics | Biology | FuseSchool
Our bodies are the ultimate factory. Every cell has its specific job to do, and is shaped to do that job perfectly. The fate of each cell is determined during the embryo stage, and then cannot be changed.
However, cutting-edge research made a major discovery for modern science: there are these wonderful cells that exist called stem cells. These cells have the ability to become any type of cell because they are not specialised.
Scientists were hugely excited by their discovery because they can be used to repair damaged organs, bones or cartilage. They could also be used to help treat diseases, such as by making new brain cells to treat people with Parkinson’s disease. Or they could be used to repair damaged immune systems, and even reverse paralysis or regrow lost limbs. The discovery of stem cells is huge for modern medicine, and could have a massive impact.
There are two types of stem cells in humans: embryonic stem cells and adult stem cells.
Embryonic stem cells are unspecialised cells that can develop into any type of cell. Adult stem cells are also unspecialised cells but whilst they can develop into many types of cell, unlike embryonic stem cells, they cannot develop into every type of cell.
Adult stem cells come from tissues such as bone marrow. As in the name, embryonic stem cells can be removed from unused embryos such as those left over from fertility treatments for example.
Whilst the discovery of stem cells offers huge potential for modern medicine, there are many social and ethical considerations that need to be taken into account. A lot of research was, and still is, needed to find out exactly how they work and how we can control them to do what we want; and not just grow uncontrollably.
Stem cells are already being used in treatments.
One big social and ethical debate around stem cells is therapeutic cloning. This is the concept of cloning a patient, growing an embryo from the cloned cells and then extracting stem cells from the embryo to grow the specific organ needed by the patient. The patient’s body would not reject this organ, as it is a made from the patient’s own cells.
Unspecialised stem cells also exist in plants and can develop into the cells of flowers, roots, or leaves. Unlike in animal cells, some plant cells do remain unspecialised and can then develop into any type of plant cell. The unspecialised plant cells group together into structures called meristems. Whereas animals stop growing in size when they are adults, plants do not. This is because meristems divide to produce cells thus enabling plants to continue to grow both in height and width throughout their life. They also produce cells that develop into flowers and leaves.

The most useful and informative video regarding stem cells in youtube
Glad you think so!
More Brain Cells... Give me some more of this stuff
I could relate to that. Absorbing knowledge is like a drug.
Currently revising from home because of quarantine and my test is tomorrow! This helps, you never fail to teach us!
Always happy to help! Best of luck on your test!
@@fuseschool thank you! its in 7mins!
How did it go?
Still hearting comments on this vid after over a year
Bek
thank you so much ! i tried revising stem cells from my revision book and it made no sense.your video however really helped me so thank youuuuuu
Glad it was helpful!
Who els his teacher told him to watch this
Me lol
mine
yup
Me
me xd
You also missed out on Induced pluripotent stem cells which are regular adult stem cells (cells from skin, fat, liver or other organs) that scientists have changed to behave like embryonic stem cells. Just like embryonic stem cells they can become into any other kind of cell in the body. These can prevent problems from adult stem cells whilst also not having to rely on donated embryonic stem cells.
Interesting video. How do you feel about mesenchymal stem cells therapy?
I am home schooling and had no idea what a stem cell was this was really helpful
Wonderful! Glad it was helpful!
thank you mr hensley for making me watch this 🕳🏃♀️
Lol thanks to my science teacher too😬😶
Nice
I got v good understanding through this video..
Thank u
Great! Glad to hear that!
thanks this really helped, because I sleep in biology too much lmao
i wish i could
Hahhahahhahahahahahahhahahhahahhahahahahahahahahahahahahahahahahahahhahaha u got the whole squad laughing
Thank You this really helped
very well explained....stemcell therapy is the talk of the world now...
Ow, my ears.
i had to watch this at school it's quite helpful
Glad you found it helpful!
Very helpful sir Ty
Most welcome!
Slow down the pace
Tnx for sharing
Our pleasure 😊
Well it was a helpful video on stem cells!😊
But can further explain about the ethical concern , I meant what does 'therapeutic cloning' mean?🥴
Helpful 🤩
Glad you think so!
I'm 38 years old and had no idea what they was ....thank you!
No worries!
Thx
No problem
great vedio
helped a lot
Glad it helped 🙂
good one g i'll c the next
Playing god, yeah right
I'm all for the science guys.
but are you all for God hmm
what if god doesn't exist? not everyone believe in god
Nothing with playing god, just be good at it.
@@damiesapphire2643 god does exist. Gov suppresses our kundalini energy(the same energy that makes god/we are an image of god according to the Bible) through low vibes like sin tv sin music,gmo junk foods, daylight savings,chemicals in hygiene products/vaccines, fear (coronavirus) etc. Raise your bodies frequency (live according to bible commands) you will experience gifts from god (CLAIRE abilities/this is why gov suppresses your energies because they will no longer be able to control you and keep you dumb down). Reprogram your nervous system is like death to ego in yoga. Allows your brain to think instead of being controlled and ends many sicknesses like anxiety. Low vibe body can be controlled through frequency but not a high vibrational body. Tesla knew this 3,6,9(9 represents god/energy in vortex math). God speaks in math and frequency. You can physically hear god if you tap in to that energy field. It’s like a radio station. We are all different radio stations(frequency). You have to get the right frequency to hear god. You can’t hear because you don’t know this info that has been suppressed from people to keep them in control as slaves. If we all raise our vibes we don’t need government and can heal ourselves in every way and god guides us so we have better lives(law of attraction ask and you shall receive).
@@user-mn7zv1tl3k aint nobody reading all that
Thank you mr crompton for making me watch this
So helpful
your a legend, FTF
my biology teacher sent me here, this helps a lot, thanks
That's great! Glad it helps!
Mine too
Helped so much but maybe next time can you talk like not that fast haha
Thank you
About Studies your welcome
I love biology so much😍
i hate it
@@jyotideshmukh7390 me tooo!!!
Halo new frnd here #antioch team
Haw is in ADNP Syndrom? Is it work?
The pace is too fast. It should pause between important pointa.
Thank you for the feedback - I will pass it on to our teachers.
Put it on 0.75x speed
You can just playback it in lower speed
Can cells that were already differentiated
Re differentiate into another specialized cell???
**Can you tell me more about totipotent, undifferentiated, multipotent and stem cells in plants**
You can't defeat me Hack Man
So, people are conflicted about the process of cloning, there's only one way to settle this...
...The Clone Wars
Are there any plans to update this? (At least change the "Currently in 2016" line?)
Bek
Thanks for your video 👍😁😁😁👍
No problem 👍
Thanks this video helpt alot
But what does specialised and unspecialised mean?
Miracles
Yep.. very useful but what you are saying can be understood by Toppers or by those who are awesomely fluent in English but for slow learners???????
10/10 on the next test baby
👍
What if going on with the piston on the body
I was wondering the same thing
I like the content but it seems to be rushed.
the background music is distracting for auditory people.
Noted!
This is my school assignment anyone else lol
I had to watch it for homework lol
@@eegeee9483 omg lol me too, where r u from?
Hello people from park
How did I find myself here.....
If anyone coming here from St Mungos academy in Glasgow, Scotland for Biology, you’ll know who I am just look at my name....
Oh hey bro.. guess who?
anyone else here from seneca ocr combined science b2.1.6
Sir I'm final BZC student... I want to know deeply about stem cells so please include much more information about these topic sir
At least your not the amiba sisters

You don't need science you just need gods love and powers have faith in god 😉
Yes, but we still need science to understand what God has created for us. I dont in any way agree with the use of embryonic stem cells, but its still good to learn so we can tell other people why we don't believe in it and why God doesn't either :)
@@eegeee9483 not everyone believes in God. If you don’t condone embryonic stem cells because of your beliefs, you have the right to not engage in it, but don’t interfere with the rest of humanity who is for it.
@@eegeee9483 I thought embryonic stem cells are natural?
Nice
Ur de first comment. Did you search, recommended, or a teacher tell you to watch?
