  • Amphiastral mitotic spindle assembly in vertebrate cells lacking centrosomes. [Journal Article]
    Curr Biol 2011; 21(7):598-605Hornick JE, Mader CC, … Hinchcliffe EH
  • The role of centrosomes and centrioles during mitotic spindle assembly in vertebrates remains controversial. In cell-free extracts and experimentally derived acentrosomal cells, randomly oriented microtubules (MTs) self-organize around mitotic chromosomes and assemble anastral spindles. However, vertebrate somatic cells normally assemble a connected pair of polarized, astral MT arrays--termed an …
  • CHANGES IN PROTOPLASMIC CONSISTENCY AND THEIR RELATION TO CELL DIVISION. [Journal Article]
    J Gen Physiol 1919; 2(1):49-68Chambers R
  • 1. The development of the amphiaster is associated with the formation of two semisolid masses within the more fluid egg substance. 2. The elongation of the egg during cleavage is possibly produced as a consequence of the mutual pressure of these two growing semisolid masses. 3. The division of the egg into two blastomeres consists essentially in a growth, within the egg, of two masses of material…
