In limb all the cells are differentiated because they perform their particular function .
Dedifferentiation happens only in case of cancer because the differentiated cells then become stem cells and go to other position and makes new cells and thus cancer metastasis .
So in normal limb, all cells are differentiated .
Thank you
Devise an experiment that would answer the following question: Do cells remain differentiated within the limb...
4. (15) You designed a polymer based hydrogel scaffold which can direct neural stem cells (NSCs) to differentiate into neurons in a linear grid. To check whether the cells differentiated, you used immunofluorescence to stain the cells for neural markers MAP-2 and DCX and NSC marker Sox2. a) What data do you expect to see from your immunofluorescence experiment if the NSCs had differentiated? b) Is this experiment sufficient? What other experiments should we do to confirm? (No need to...
How would I conduct an experiment to answer the following question?? Do I do western blotting, how am I gonna test for both of these things individually?? What genes are specifically regulated by Myc-Mad but not Myc-Max. And, vice versa (Myc-Max but not Myc-Mad).
Which of the ONE following characteristic is usually NOT TRUE of cancer cells and the tumors that result? (i.e. all of the answers below are correct except for one-- select the incorrect answer!) Cancer cells do not migrate within the body. Cancer is usually caused by multiple acquired mutations. Cancer cells evolve over time--becoming more potent and more deadly. Cancer cells have dysregulated (uncontrolled) cell division activity. Some cancers are preventable. Question 9 (4 points) Which of the following of...
Treatment cause the rhubarb cells to be plasmolysed after 5 minutes If an epidermal peel of rhubarb cells (from the edible petiole of the plant) is placed on a microscope slide and immersed in water, then viewed through a light microscope they look like those in panel A. If placed in 1.0M sucrose or 1.0M urea solution the cells become plasmolysed within several minutes and look like those in panel B. The vacuoles of these epidermal cells are full of...
Would a reduction in intracellular calcium ions within the sarcolplamic reticulum of heart cells (those in the conduction pathway and the contractile cells) lead to a positive or negative chronotropic effect, inotropic effect and lusitropic effect? Explain your answer. (4.5 marks)
Suppose that in an experiment you observed 113 cells in
interphase, 24 cells in prophase, 9 cells in metaphase, 12 cells in
anaphase, and 3 cells in telophase stages. If the complete cell
cycle (i.e. G1+S+G2+mitosis; see Figure 1-2 of the Lab Manual)
requires 24 hours, calculate the average duration of each stage in
the cycle. Show all calculations.

Do the following solutions cause cells to undergo crenation, hemolysis or neither. A) 2.0% NaCI ______ B) 5% glucose ______ C) distilled water _____
Please answer question 4 with a full explanation.
4. (9 points) Multi-step synthesis. Devise a synthesis for the target molecule starting from benzene and small alcohols with no more than two carbons. You can use any inorganic reagents necessary target 5. (10 points) Analysis of 'H NMR spectrum. Below is the 'H NMR spectrum of the product from this week's experiment.
Read the scenario and answer the question- A researcher plans to do an experiment in the college setting concerning the effects of class size on attendance in a first year law course. He has four levels of size, namely, 15, 25, 40, and 60 students. Four colleges are involved in the study, each having eight first-year law classes, two of each class size. The researcher can assign students at random to a class within a college, but he cannot assign...
Question 1. Different types of cells have different types of integral membrane proteins. What would you expect to reside in the plasma membrane of an epithelial cell that might be absent from that of an erythrocyte? How do such differences relate to the activities of these cells? Question 2. In an experiment, let us say you plan to use liposomes in an attempt to deliver drugs to fat or muscle cells. Is there a method in which you might be...
