Z-axis of chick myogenic cells showing the differences in the distribution of microtubules, and intermediate filament desmin and nuclei between finger-shaped fibroblasts and mushroom-like muscle cells after 72 hrs of cytochalasin B treatment. The 3-m apart images were taken from a stack of 1-m interval slices, acquired <a href=\"https:\/\/www.adooq.com\/uaa-crosslinker-2.html\">UAA crosslinker 2<\/a> using a laser scanning confocal microscope. Cells were labeled with antibodies against -tubulin (green) and desmin (red), and with DAPI (blue). Compare the spread and flat fibroblasts with the round and thick desmin-positive myoblasts. Note that the fibroblast nuclei are located in the 6 and 3-m slices whereas the myoblast nuclei are UAA crosslinker 2 present in all the slices.

Sequential projections in the X and Y-axis from a stack of 1-m interval images, acquired using a laser scanning confocal microscope. Cells were labeled with antibodies against -tubulin (green) and desmin (red), and with DAPI (blue). Note the desmin signal was detected at the periphery of the myoblast but not observed in the fibroblast. Microtubules are well spread in the fibroblast and concentrated in the center of the round myoblast. Both cells are binucleated.

The sections were reconstructed from a stack of 22 images with 1-m interval, acquired using a laser scanning confocal microscope. Cells were labeled with Rho-phalloidin (red), an antibody against -tubulin (green), and DAPI (blue). Note that actin accumulates at the tip of the fibroblast fingers (close to the substrate), whereas microtubules (that label most of the cell cortex) do not localize to the very extremity of the cell.

Sequential projections in the UAA crosslinker 2 X and Y-axis from a stack of 1.4-m interval images, acquired using a laser scanning confocal microscope. Cells were labeled with an antibody against sarcomeric&#8211;actinin (red) and DAPI (blue). Note that the round myoblast contains perfectly striated myofibrils, as seen in the Z-line staining of sarcomeric&#8211;actinin. The round myoblast has UAA crosslinker 2 4 nuclei.

During the initial 20 min of recovery after 72 hrs of CB treatment, myogenic cells remain globular shaped whereas finger-shaped fibroblasts loses their finger protrusions and changes into flatten multinucleated spread cells. Time is shown in the top left of each image. The movie was taken from the region shown in Fig 8D inset.

Phase contrast microscopy images of chick myogenic cells treated on day 2 with shows DMSO for 3 days are shown (A-C). Note that cultures treated with DMSO are indistinguishable from control-untreated cultures (compare A and B). In both conditions (control-untreated and DMSO-treated cultures) it is possible to see the formation of long multinucleated myotubes (A and B). Cultures treated with CB for 3 days show finger-shaped fibroblastic cells (indicated by white arrow in C) <a href=\"http:\/\/www.ncbi.nlm.nih.gov\/entrez\/query.fcgi?db=gene&#038;cmd=Retrieve&#038;dopt=full_report&#038;list_uids=15529\">Sdc2<\/a> and globular-shaped myoblasts (indicated by black arrow in C).
