Neural stem cells (NSCs) give rise to all cells of the nervous system. You have uncovered a potentially new sight of neurogenesis within the rodent substantia nigra and isolated the cells. These cells have shown to be an important site of where neurogenesis needs to occur after neurodegeneration to prevent diseases. Your principal investigator wants you to do a series of experiments to fully characterize the identity of the cells. Where are these two niches located? (4 pts) What marker...

The difference between embryonic and adult stem cells is that a.Embryonic stem cells are normally present during development, adult stem cells are only present when gene therapy is used to induce them to form. b.Both adult stem cells and embryonic stem cells can be treated with growth factors to become any tissue type in the body. c.None of the above. d. Embryonic stem cells are pluripotent, adult stem cells might be pluripotent OR multipotent. e.Adult stem cells are multipotent, embryonic...

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...

Neural communication Describe in detail the steps in chemical communication between neurons. Please include: action potential opening voltage-gated Ca++ channels Ca++ entering the pre-synaptic terminal Ca++ working with calmodulin to release transmitter from synaptic vesicles into the synaptic cleft the transmitter binding to receptors on the post-synaptic membrane the vesicle being recycled the transmitter being broken down/recycled/diffusing away.
