In the differential staining, we can distinguish cellular structures according to the affinity for basic dyes, assets or a mixture of both. When placing the smear under the microscope, it is convenient to initially determine which area of the smear we are observing, head, body or tail. As we scan the sample, we are able to see the appearance of the cells. In the head of the sample, the area in which the drop was placed, a greater cellularity is observed. The uthrocytes will be very close, forming aggravates and the coloration becomes grayish. This zone should be avoided in order to be able to distinguish the different cell types present. As we scan the sample in the direction of the extension, the concentration of cells will decrease. The optimum area will be the center or body of the smear. The cells are more separated and the actual coloration acquired by the blood of the smear can be seen with the gym's staining. Blood blood cells appear pink, leuker cells show the nuclei staining purple and their cytoplasm impale pink. As you will expect, the most abundant cell type is the uthrocyte. It represents 99% of the blood cells. They are flexible and via concave discs. They lack a cell nucleus. The shape is the one that causes a clear halo or descentral of the cell when the light of the microscope closes it. This morphology provides essential properties for physiological cell function such as deformability and stability when traveling the circular toll system, and specifically the capillary network. In addition, it maximizes the surface for cellular gas exchange. As you can see in the right image, the uthrocyte of other spaces may have different characteristics. In this case, an ellipse of dye and nucleated uthrocyte extension is shown very different from the human ones. At a higher magnification, the uthrocyte morphology is clearly seen. White blood cells, also called leuker cells, are shown. They are the cells of the immune system that are involved in protecting the body against both infection disease and foreign invaders. Monocytes are the largest type of leukocyte. They contain kidney-shaped lurved nuclei, and these cells are able to migrate to tissues where they will differentiate into tissue macrophages when needed. We continue scanning the preparation and looking at the cells' types present. The lymphocyte is the smallest of the leuker cells. All the different types of lymphocytes exist such as B cells, T cells, and natural killers. Immunihistochemical techniques are required to differentiate them. Vinyl sites, also called polymol for nuclear leukocytes, are characterized by the presence of granules in their cytoplasm. They are divided into three types according to the staining characteristics of their granules. Neutrophils, ears and filth, and basophils. The most abundant in human blood are neutrophils. These granules are not observed with this type of staining. Eosinfilth and basophils are less frequent. Playlets can also be found which are cytoplasmic fragments of the precursor cell, the mega-carosit. They are actively involved in clotting and may be found isolated or cloted. They are infrequent in these samples because this mirror was click-knit on right after blood extraction. Here, a polymol for nuclear cells can be seen characterized by having abundant granules that do not allow us to see the polymorphic nucleus. It is a basophilth. If it is observed with a 104 magnification objective, its blueish granules can be seen since they have been stained with the basic metal in blue dye, present in the gym's staining. With 104 magnification objective, the previously described cellular types can be observed in more detail.
