Development of Oriented Motion in Regenerating Hydra Cell Aggregates

摘要: Abstract Hydra can regenerate its complete adult form from aggregates of dissociated cells. Aggregates hydra cells are made by dissociating tissue into a suspension and then re-aggregating the centrifugation. An aggregate formed in this way is disorganized mass individual does not possess any regeneration polarity. In study, we analyzed development motion cell during stages which new body axis was being established. Two perpendicular diameters (widths) binalized projection images an were continuously measured order to detect changes form, i.e., motion. Between 30–35 hr, when still appeared spherical, slight along distinct detected with simple expansion size mass. After that, quick twitches axis, also seen intact hydra, began develop. The corresponded future regenerated animal,...
