RESIDENT CELLS – FIBROBLAST – 2
Three fibroblasts are shown in this image, placed between collagen fibers.
The fibroblasts have have many long and tortuous cytoplasmic extensions but usually only a small part of them can be seen joining the end of their nuclei. Their cytoplasam stains similarly to collagen fibers and for these reason, separate stretches of fibroblasts are not easily observed in sections. These cells can be better studied under an electrn microscope.
Very often the fibroblasts are identified in connective tissues by their slender nuclei with rounded ends.
Their cytoplasm becomes highlighted in green after placing the cursor or clicking on the figure. Nuclei are highlighted in gray.
In one of the fibroblasts of this figure, positioned vertically, its nucleus and cytoplasm can be easily seen. The nucleus is elliptical with rounded ends.
There is another fibroblast immediately to the right of the previous one whose nucleus forms an angle. Its cytoplasm is not visible.The third fibroblast is in the lower left corner of the figure. Its nucleus is clearly visible, but very little of its cytoplasm can be seen.
