Summary Introduction
Introduction:
Embryonic stem cell derived from five to six day old embryo that are self replicating and are known to develop into cells and tissue of the primary germs layers that develop different body organs whereas adult stem cell found among specialized and differentiated cells in the tissue or organ after birth and these are more restricted ability to produce different cells types to self renew.

Students have asked these similar questions
Which of the following best describes the concept of cell differentiation during the development of a multicellular organism?
A. During development, all of the genes in the embryo's cells are expressed at first, but fewer and fewer are expressed as time proceeds.
B. During development, different sets of genes are deleted from different cell types so that at the end of development, each cell has only the genes it needs.
C. During development, different cells become specialized to have different phenotypes even though they all originated from the same cell.
..
Why is it easier to manipulate embryonic stem cells to differentiate into various tissues than it is to manipulate a typical adult cell?
a.
As cells develop, signaling pathways can cause some genes to be turned off during development.
b.
Adult cells have different DNA content than do embryonic stem cells.
c.
Emybronic stem cells pose less of a threat for organ rejection as do an individual s own adult cells.
d.
It is no easier to manipulate emybronic stem cells to differentiate into various tissues than it is to manipulate a typical adult cell.
Which of the following is typical of cancer cells?
A. The parent cell of the tumor contains a single mutation in a single checkpoint gene.
B. Malignant cells migrate.
C. Cancer cells lose the ability to divide.
D. Products of oncogenes inhibit mitosis
E. Benign tumors invade normal tissue.

- Which of the following cell types would you expect would grow and divide continuously if given sufficient nutrients and mitogens (select all that apply)? A. Carcinoma cells from a liver biopsy B. Embryonic Stem Cells C. Normal human liver cells D. HeLa Cells E. Brain cells from micearrow_forwardNew treatments for several conditions are being developed using stem cells in medical waste, such as biopsy material, teeth, menstrual blood, umbilical cords, and fatty tissue removed in liposuction. For example, fat samples from injured horses are used to grow stem cells to treat tendon injuries. Explain how the two defining characteristics of stem cells enable them to be used to replace damaged or diseased tissue, so that the new tissue functions as opposed to forming a scar.arrow_forwardHeLa cells are a line of cells grown in laboratory culture that has been used extensively in research. This cell line was originally derived from malignant cervical cancer cells that were removed from a woman named Henrietta Lacks in 1951. They were grown in culture and shipped to research labs around the world where they have been used in many important experiments. Like HeLa cells, many other cell lines were originally taken from cancerous tissue. What are the advantages to using cancer cells for developing cell lines? Why not use normal tissue?arrow_forward
- During development, cells become a. differentiated before they become determined. b. determined before they become differentiated. c. determined by the loss of genetic material. d. differentiated by the loss of genetic material.arrow_forwardHow does gene activation lead to cell differentiation? Explain the correct answer and explain why the others are wrong. A. Different genes are activated in different cells, causing each cell to have a unique funcation B. The same genes are actives in every cell of your body, causing every cell to function the same C. Certain cells only have parts of DNA that causes cell deferentiation D. Unique genes are in different cells, causing each cell to have a unique functionarrow_forwardThe normal function of the Rb protein is toa. act as a brake on cell division.b. produce retinoblastoma.c. facilitate retinal pigmentation.d. initiate DNA replication.arrow_forward
- One important biological effect of a large dose of ionizing radiation (like X-rays) is to halt cell division. How does this occur? To answer this question, state the name and role of 2 specific and important proteins involved in the process. What happens if a cell has a mutation that prevents it from halting cell division after be irradiated? Be specific and detailed. An adult human who has reached maturity will die within a few days of receiving a radiation dose large enough to stop cell division. What does that tell you about cell division? In addition, name 2 different/unique cell types that would be primarily affected.arrow_forwardAnswer the following question. 1. What are the benefits of specialized cells? 2. What is Stem cell?arrow_forwardWhich of the following traits are common to many cancer cells (more than one answer may be correct)A. Uncontrolled growth and divisionB. Chromosomes abnormalitiesC. Absence of a cytoskeletonD. Decreased adhesion to other cellsarrow_forward
