In this video, we look at what is meant by stem cells. We then look at the uses of stem cells in medicine. Finally, we explore stem cells in plants and how these can be useful.

Hi Sir- in therapeutic cloning, why do you call the cell an embryo even though it hasn’t been fertilised? Thanks.

@Freesciencelessons 2 года назад

Effectively, it behaves as an embryo undergoing mitosis and differentiation. So it's simply called an embryo.

Sir, is therapeutic cloning when an embryo from an animal can be killed for the use of stem cells if the parents don't want the child?

@itzhena5301 4 года назад

Yup

@user-ic7rj2gv2z 3 года назад

the reason for therapeutic cloning is to make the same stem cells as the subject, therefore, if the "parents don't want to child", there wouldn't be a reason for therapeutic cloning therapeutic cloning is creating an identical stem cell copy of your own cell

Thank you for this video! Do human stem cells stop differentiating and dividing after they first divide and differentiate, or, like plant cells, can they divide and differentiate after the first time they differentiate?

@Freesciencelessons 6 лет назад

Thanks for the comment. Currently, scientists think that once human stem cells have differentiated, they cannot reverse to a different cell type.

@samithassan573 6 лет назад

Depends On Which Human Stem Cells Your Referring To.

@Hakimi_No.1 Год назад

please could you explain why stem cells are found in plant meristems?

@Freesciencelessons Год назад

Plant meristem tissue is where mitosis takes place. The new cells then differentiate to form different tissues eg stem, flowers etc. That means that these cells have to be stem cells, since stem cells can differentiate to form different types of tissue.

@Hellothere-zs3tt 3 года назад

What's the difference between embryonic stem cells and stem cells?

@user-ic7rj2gv2z 3 года назад

the difference is that embryonic stem cells can change into any type of cells, while regular stem cells will only be able to change into limited types of stem cells. (of course, this is only in humans) also, embryonic stem cells can only be found in the embryo stage while stem cells such as the bone marrow stem cell can be found anytime

Sir in the 2018 GCSE biology paper there was a question on the process of Therapeutic cloning and how the embryo (that has the same genes as the patient) is made, but it isn't specified on the spec.
