I found our discussion on the “identity” of cells to be particularly interesting. For example, the direction in which a stem cell will grow depending on the several different factors it is exposed to. For example, the characteristics of the surface the stem cells are mounted on.
I found the that different cells contained different polarizations across their membranes to be interesting. Especially, how research today has shown that artificially polarizing the membranes of less proliferative cells can result in them developing a specific identity to a specific type of cell, and visa versa.
