Mouse adult lymph node 08.jpg

Migration of the B cell-T cell conjugate in the stromal cell network in the lymph node.


  1. Within lymph nodes T-helper cells(red) activate B-cells.
  2. B-cells (green) then move to germinal centres and proliferate.
  3. Mature B-cells stop dividing, migrate to regions around germinal centre (mantle zone).
  4. Contact follicular dendritc cells (cyan, not bone marrow derived).


The movie shows the 45-min time lapse images recorded every 30 s.

  • green - cognate antigen-specific B cells
  • red - helper T cells are stably conjugated.
  • cyan - are primarily irradiation-resistant stromal cells.

The mouse lymph node was imaged ex vivo by TPLM 36 h after immunization. Elapsed time is shown as hours/minutes/seconds. The image volume is 100 μm (x)×100 μm (y)×60 μm (z). The scale bar shows 30 μm on the nearest x-y plane from the viewpoint.
