Figure 5. Colocalisation of CD2 and LFA-3 in the contact of NLC and CLL cell.

(A) Green CD2 acquisition by CLL cells stained by red LFA-3 after 5 min or 4 h of contact with NLC stained with green CD2 observed by confocal microscopy at 37°C (left: 5 min of contact, right: 4 h of contact). (B) Orange contact point characteristic of the colocalisation of green CD2 on NLC with red LFA-3 on a CLL cell placed under the NLC.
