An overview of early development of a zygote to an embryo. Embryonic and somatic stem cells.
Video Rating: 4 / 5
@Sitara04 both of them.the just follow the cell cycle.initially they dublicate and after the divide via mitosis.(Thats what i think)
@WayeYoung its the same thing bro.its called and Blastocoel as well.both are correct
@khanacademy
i have heard that scientists had found a way to trick the female egg and make it think that it has been fertilised. The tricked egg undergoes division and develops and gives an undisputable source of stemcells.
Potential does not equal realisation.
Blastocoele though
Great video
@infidelguy I agree but like the maker of this video, I really don’t want to take a side on the issue. Having said that, and maybe this is different, many people do hold funerals for miscarriages. Now, whether that’s your custom, and whether those miscarriages are 3 weeks or more than three weeks, that is another thing. Either way, those are touchy subjects… And sad no matter what camp you’re in.
Great to see people enjoying this video- I really liked it!
interesting vid.. but please learn how to pronounce ‘differentiation’…thanks.
Thank you! I really enjoy learning, but school sucks the fun out of it for me. This is great. Thanks! I love it!
best vid on stem cells on youtube! this is the one that gave me the most understanding.
thanks alot
Just a Q : Do the stem cells DUPLICATE or DIVIDE? im a little confused…
Wow, not only is it that you tutor in math, but you also tutor in medical/biology science!?
This seems like an obvious “solution” to me, why not use the discarded zygotes from invitro fertilization for stem cell research? That seems like it would be efficient, and not wasteful.
Your videos enlighten me. Im kind of just sitting here chilling right now though but Im probably going to watch this another two times because I really find interest in how these differentiations in cell plasticity can exhibit so many different characteristics within our body. Like for example being something as simple as a cut.
Really helpful. Thanks.
Thanks for the great explanation. I havent’ taken Biology for many years, and Now I understand the Stem Cell origin!
Speaking of the process of embryo destruction, spontaneous abortion also occurs. Most women have had a spontaneous abortion in which their bodies have rejected implantation for a wide variety of reasons. I don’t see people holding funerals for naturally aborted 3 week embryos.
Great point Sal. Thanks!
About freezing, Sal, maybe some time you’ll make a video about cryogenics? From my understanding, cells only die if they’re frozen/unfrozen unevenly.
What do you do not know?
You’ve got videos of everything and you explain it well. Thank you very much for such videos.
I have a huge respect for Khan Academy, Sir I salute your contribution for free knowledge
