Describe the potential mechanisms that are thought to be
involved in how stems cells might ‘work’. Your ‘list’ may not be
relevant to all stem cell types, or therapies, but you need to
consider them all. (Hint: there are more than 3!)
Stem cells are part of the body's normal repair system. There main function to replace damaged cells in the body.
Human body is composed of over 200 cell types. Each designated to different and particular function.
Undifferentiated biological cells that can be converted into other cell types and can divide to produce more stem cells.
Types of stem cells:-
Properties of stem cells to differential into different cell type is called potency

Discuss how bacterial cells might resist phage infections. In your response explain the mechanisms involved and speculate on the possible strategies of resistance. (15)
How might the loss of components of the apoptosis machinery render cancer cells more susceptible than normal cells to certain types of cell death?

Describe how the presence of possible outliers might be identified on the following. (a) histograms higher center bar than surrounding bars gap between the first bar and the rest of bars or between the last bar and the rest of bars gap around the center of the histogram O large group of bars to the left or right of a gap higher far left or right bar than surrounding bars (b) dotplots large groups of data to the left or...
Describe how a selectively permeable membrane is involved in osmosis. Include the role that the solute concentration plays in the direction of water movement. Now think about how this process may differ between plant and animal cells. For instance, how might cell walls disrupt the role of solute concentration and cause one to refute a hypothesis for the direction of water movement based on water concentration alone?
Cloning Human Embryonic Stem Cells Cloning is now possible by inserting a skin cell from a baby into an unfertilized human egg that has had its own DNA removed. This produces a blastocyte (an undifferentiated embry onic cell), which includes stem cells identical to the baby's. With this technique it is possible to make genetically identical embryonic stem cells from any cell in the human body. This would remove the need to harvest these cells from existing embryos. Theoretically these...
1. Mature B cells require particular receptors to be engaged by ligand to stimulate these cells to become antibody-secreting cells. Fill-in the table below with the receptor(s) on naïve B cells that transmit each signal and the corresponding ligand(s) that engage that receptor. (6 pts) Receptor(s) on B cell Ligand(s) Location in body where receptor engagement occurs Signal 1 Signal 2 b. Briefly describe what happens to mature B cells that receive Signal 1, but not Signal 2? (2 pts)...
please answer all parts of this question 2. Consider the junction potential a. Describe how and why a junction potential occurs. What is the error, in terms of concentration, if a junction potential changes the true b. cell voltage by 1.50 millivolts in a potentiometric determination of an analyte? Show the relevant calculations. c. Describe at least one way in which the error due to a junction potential can be eliminated or at least significantly reduced.
2) List and explain all possible mechanisms whereby a radical prostatectomy leads to male urinary incontinence. Hint, prostatectomy was mentioned in multiple lecturers, and you might also need to research your answers. You are searching for different mechanisms causing incontinence after surgical prostate removal. 3) Try to describe and explain the different physiological components responsible for the male erection response during the time when Pudendal arterial blood flow is essentially zero and the intracorporeal blood pressure is much greater than...
1. Describe your next ideal work opportunity. 2. Describe the type of competition you are likely to have in this particular marketplace. What type of compensation might you be looking at? Is there a lot of competition in the geographic area you're interested in? Note: Be thinking ahead of how you can solve for some of these by the value and skills you possess! 3. List four skills or values you possess and describe in detail how this would be...
