What is the primary concern related to the use of early stage blastocysts in stem cell research?
Ethical considerations and the destruction of embryos
Which type of stem cells are rich in multipotent stem cells and can serve as an insurance for possible diseases in later life?
Adult stem cells
What is a limitation in using adult stem cells for therapy?
They may contain more DNA abnormalities
What are cancer stem cells (CSC) capable of?
Self-renewal, differentiation, and tumorigenicity
What is a characteristic difference between induced pluripotent stem cells (iPSC) and embryonic stem cells (ESCs)?
iPSCs have differences in methylation patterns/epigenetic modifications
What are organoids?
3D structures grown from stem cells with organ function
What is the primary purpose of embryo cloning?
Cloning cells for therapeutic purposes
Which type of cloning is used to produce clonal embryos that will be grown into full-grown adult clones?
Reproductive cloning
What was the outcome of Gurdon's experiment on cloning a frog via somatic cell nuclear transfer?
It resulted in the production of a clone of frog B which developed into a tadpole.
What is a misconception about cloning?
Clones have identical phenotypes due to carbon copies.
What is a risk associated with cloning?
The cloned organisms may experience premature death due to epigenetic factors.
Test your knowledge about the development of embryonic stem cells and their potential to self-renew or differentiate into specialized cells. Explore the stages from zygote to blastocyst and understand the importance of self-renewing stem cells.
