English: Time lapse of a Rac1J11 white pre-pupal haemocyte on 0.2% gelatine extra-cellular matrix. Time lapse imaging was performed on primary haemocytes, excised from the white pre-pupal life stage of Rac1J11 D. melanogaster, in ex vivo conditions on a 0.2% gelatine ECM. The haemocyte has been cropped to 150% greater than its original, and has been rendered from an 80 frame time lapse, which was taken with a frame rate of 15 seconds. The haemocyte was observed to produce the active non-polarised phenotype, and showed some minor movement around a fixed axis.
