Question

This process is induced in the germarium of Drosophila by the Bag-of-marbles protein, since it only occurs far from the cap cells’ niche. (0[1])Flow cytometry detects cell surface markers called “clusters” of this process. (20[1])In (20[1])Waddington’s analogy to a ball rolling down a hill, this process pushes an HSC down either the myeloid or lymphoid lineage. This process (20[1])can be reversed (20[1])by reprogramming Sox2 (20[1])and Oct4, (20[1])two (0[1])of the (20[1])(*) Yamanaka factors. (0[2])Progenitor (10[1])cells (0[1])undergo this process (10[4]0[2])or self-renewal. (10[1]0[1])Totipotent cells in the morula (10[1])undergo this process (10[1])when they become pluripotent (10[1])cells (10[1])in the blastula, (10[1]0[1])which then further undergoes this process to form the three germ layers. (0[2])For 10 points, name this process by which stem cells mature (10[2])and (10[1])specialize. (0[3])■END■ (10[5]0[3])

ANSWER: cellular differentiation [or differentiating; or clusters of differentiation; accept differentiation of specific cell types, like white blood cell differentiation; prompt on CD; prompt on specialization or maturation until either of those words is read; prompt on losing stemness or losing potency; prompt on cell division or mitosis; reject “meiosis”]
