Are radial cleavage in embryonic cells commonly found on insects?
No, radial cleavage is not commonly found in insect embryonic development. In insects, cleavage is typically superficial and holoblastic, meaning the entire egg divides into individual cells without forming distinct layers. Radial cleavage is more commonly seen in deuterostome animals like echinoderms and chordates.
Where is active telomerase found in?
Active telomerase is commonly found in stem cells, germ cells, and cancer cells. It is also present in some cells undergoing rapid proliferation, such as embryonic cells.
What are the techniques to produce embryonic stem cells and embryonic germ cells?
Embryonic stem cells are typically derived from the inner cell mass of a blastocyst, a very early stage of embryonic development. This involves in vitro fertilization of an egg cell with sperm to form a zygote, which then develops into a blastocyst. Embryonic germ cells are derived from primordial germ cells found in the embryo. Techniques for producing these cells involve careful manipulation of embryonic development and culture conditions to isolate and maintain these specific cell types.
How does one gain a deeper understanding of embryonic stem cells?
Embryonic stem cells are a very important area of biotechnology, which is best researched at an accredited university. Specific reading material can be found in such universities' libraries.
Why do researchers prefer to use embryonic stem cells in medical research?
One reason researchers prefer to use embryonic stem cells instead of adult stem cells because adult stem cells are often found in limited quantities, are difficult to isolate, and the older the donor, the less stem cells they have.
Do embryonic stem cells contain half the number of chromosomes found in a zygote?
No. Stem cells are diploid just like any other body cell.
What are the similarities and differences between research on and the use of adult stem cells and embryonic stem cells?
One major difference between adult and embryonic stem cells is their different abilities in the number and type of differentiated cell types they can become. Embryonic stem cell can become all cell types of the body because they are pluripotent. Adult stem cells are thought to be limited to differentiating into different cell types of their tissue of origin.
What are the types of stem cells?
There are five basic stem cells classifications there is embryonic stem cells, fetal stem cells. There are the Umbilical cord stem cells, placenta stem cells, and lastly there are adult stem cells.
What is difference between embryonic stem cells and adult stem cells?
An embryonic stem cell potentially can develop into ANY cell in the body theoretically without limit to replenish, and an adult stem cell is only able to mature into a specialised tissue cell from which tissue the cell is positioned.
What is the organelles found abundantly in the flight muscle cells in insects and birds?
mitochondria
What are the three main types of stem cells?
The three types of stem cells are Totipotent, Pluripotent and Multipotent. Edit By Camden Stevens: there are actually four- Totipotent, Pluripotent, Multipotent, and Unipotent stem cells. Toti, Pluri, and Multipotent are all embryotic stem cells, which means they occur in the embryo before the child is actually born, then pluripotent and multipotent last until adulthood. Then unipotent stem cells occur through adulthood to the rest of the life.
What are the three stages of the human life cycle when stem cells can be found?
The three stages of the human life cycle when stem cells can be found are embryonic stage (during early embryonic development), fetal stage (during fetal development), and adult stage (in various tissues and organs throughout adulthood).
