The current findings suggest that after the process of affinity maturation in germinal centers, plasma cells develop into one of two types of cells: short-lived plasma cells (SLPC) or long-lived plasma cells (LLPC). LLPC mainly reside in the bone marrow for a long period of time and secrete antibodies, thus providing long-term protection.
Other widely used metachromatic stains include the family of Romanowsky stains that also contain thiazine dyes: the white cell nucleus stains purple, basophil granules intense magenta, whilst the cytoplasms (of mononuclear cells) stains blue, which is called the Romanowsky effect. The absence of color change in staining is named orthochromasia.
Blood and lymph are classed as specialized fluid connective tissues that do not contain fiber. [2] [3] All are immersed in the body water. The cells of connective tissue include fibroblasts, adipocytes, macrophages, mast cells and leukocytes. The term "connective tissue" (in German, Bindegewebe) was introduced in 1830 by Johannes Peter Müller ...
One of the most reliable distinguishing factors from plasmacytomas and plasma cell granulomas, is the polyclonality of the plasma cells involved with plasma cell granulomas. [3] PCGs that manifest in the mouth, specifically the gingiva, have been seen to exhibit similar physical characteristics of other conditions such as epulis, fibroma ...
Masson's trichrome is a three-colour staining procedure used in histology. The recipes emerged from Claude L. Pierre Masson's (1880–1959) original formulation have different specific applications, but all are suited for distinguishing cells from surrounding connective tissue.
The cords of Billroth (also known as splenic cords or red pulp cords) are found in the red pulp of the spleen between the sinusoids, consisting of fibrils and connective tissue cells with a large population of monocytes and macrophages.
There are multiple ways of classifying tissues: one classification scheme is based on tissue functions and another analyzes their cellular components. Stromal tissue falls into the "functional" class that contributes to the body's support and movement. The cells which make up stroma tissues serve as a matrix in which the other cells are ...
The red pulp of the spleen is composed of connective tissue known also as the cords of Billroth and many splenic sinusoids that are engorged with blood, giving it a red color. [ 1 ] [ 2 ] Its primary function is to filter the blood of antigens , microorganisms, and defective or worn-out red blood cells.
