[Spectrophotometric study of the initial stage of lymphocyte transformation]

Results are presented of temporal variations of light current which passed through mouse lymphocyte suspension at introduction of phytohemagglutinin mitogen or concentrated cell suspension on liquid surface. Based on comparing the calculated time of phytohemagglutinin molecules diffusion, velocity of lymphocyte precipitation and recorded time of the system response a hypothesis is advanced concerning the existence of an ordered structure formed by cells in suspension, and a relay--race transmission of surface disturbance deep into the volume.
