Are neural crest cells a form of stem cell if so what type?
Homework Answers
Neural crest cells derived from embryonic ectoderm cells in
chordates of
group cristozoa.
These cells give rise to or get differentiated into melanocytes,
glial cells,
neurons of peripheral system, bone, smooth muscle, etc.
When these cells are grown in a medium, these cells differentiate
into
a variety of cells. This suggests that these cells are stem
cells.

(1) Explain why neural crest cells migrating in the path2 migrate into the anterior but not posterior somite. Use terms: ephrin, Eph. (Ept) (2) In the intact condition of mouse, the Notch signaling keeps the neural precursors in an immature c proliferation state to expand the number of neuronal cells in later. Explain what will happen if the constitutive active form of Notch (continuously active Notch) is...

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...
