Fig. 4. Tracing fusion of non-adherent cells using fluorescent dyes of two different colors (A~P). Non-adherent cells were collected and stained (separately) with green or red cell-tracker fluorescent dyes; cells of each color were returned to the originating culture. During the first few days, some of the labeled cells attached to the dish, whereas some other cells remained non-adherent (A~D). Cytoplasmic fusion of green and red labeled cells (yellow in the overlay) was observed in syncytium-like structures (E~H), bubble-like structures (I~L), and multinucleated niche areas (M~P). Migration of labeled cells into the existing and newly formed niche areas was detected (H, L, P; arrows).
