“…Their number increased as the age advances in both the sexes as mentioned by Vijayaragavan (1988) in White Leghorn chicken. Mast cells density was higher in close proximity to the arterial vessels and medullary region of thymus than in the cortical region as stated by Karaca et al, (2006) in chicken and Leena et al, (2008) in Giriraja birds.…”

“…In the present studies, researchers were seen alcian blue‐positive mast cells while they were not seen pink‐red colour safranin mast cells on lymphoid organs in turkey (Karaca, Yörük, & Uslu, ), avian lymphoid organs (Karaca, Yörük, & Uslu, ) and caecum of quail (Yıldız et al., ). In the study on the chicken tongue (Karaca & Yörük, ), sow oviduct (Özen et al., ), bovine reproductive tract (Saruhan, Sağsöz, & Akbalık, ) and quail lungs (Harem, Liman, & Alan, ) were reported that mast cells were located different area.…”

This study was conducted with the aim of determining the morphology, distribution and heterogeneity of mast cells in the tongues of seagull (Larus fuscus), common buzzard (Buteo buteo), goose (Anser anser), white stork (Ciconia ciconia) and Gerze rooster. The study used five samples of tongue material from each of the healthy adult avian species. The samples were fixed in 10% neutral-buffered formalin (NBF) solution, then, after routine tissue follow-up, the samples blocked with paraplast. Cross-sections with 5-6 μm of thickness were stained with the 0.5% toluidine blue and alcian blue/safranin O (AB/SO). In all five avian species, it was found that the mast cells were in different sizes and round, oval or spindle-shaped based on their place of distribution. Mast cell numbers were determined in stained with toluidine blue, examined ×40 objectives in a 1 mm area. It was observed that mast cell density in subepithelial lamina propria and microscopic papilla was higher in the tongues of all species. Mast cell distribution and heterogeneity varied through the tongue, and there were more mast cells in the dorsal side of the tongue than the ventral side. The highest amount of mast cells was found in the tongue of the Gerze rooster among all five species. In the tongue cross-sections stained with the combined method of alcian blue/safranin O (AB/SO), the mast cells were stained as AB (+), SO (+) and AB/SO (+) (mixed).

“…Mast cells may produce, store, and release a large number of bioactive and vasoactive mediators that continuously modulate the tissues in which they are located (19). The number and density of mast cells in tissues vary depending on factors such as age and pathogens (20). Mast cells can reside in all layers of the gastrointestinal tract, but most of them are found in the lamina propria of the mucosa and the submucosa (21).…”

Mast cells are located near surfaces that contact the external environment, such as the skin, respiratory, and digestive systems. The number of mast cells in tissues can vary depending on the location and immunological status of the host. This study aimed to determine the number and heterogeneity of mast cells in the broiler ileum during the post-hatching period. The number and heterogeneity of mast cells were studied in the ileum tissue of 0-, 7-, 21-and 42-day old broilers. Mast cells were stained metacromasically with toluidine blue in all groups. Mast cells were seen in all layers of the ileum, especially in the lamina propria and submucosa. They were also observed around blood vessels and between smooth muscle cells in the tunica muscularis layer. In the broiler ileum, both subtypes of mast cells were seen: blue-colored AB (+) and red-pink colored SO (+) mast cells. AB (+) mast cells were observed in all age groups, whereas no SO (+) mast cells were found in the 0-age group. SO (+) mast cells were first detected in the ileum tissue on the seventh day after post-hatching. As a result, the number of mast cells was found to increase with age, which was statistically significant. Kuluçka sonrası farklı dönemlerde broyler ileumdaki mast hücrelerinin sayısı ve heterojenitesi ÖZET:Mast hücreleri, deri, solunum ve sindirim sistemleri gibi dış çevre ile temas eden yüzeylerin yakınında bulunur. Dokulardaki mast hücrelerinin sayısı, konağın konumuna ve immünolojik durumuna bağlı olarak değişebilir. Bu çalışmada, kuluçka sonrası dönemde broyler ileumdaki mast hücrelerinin sayısının ve heterojenliğinin belirlenmesi amaçlanmıştır. 0-, 7-, 21 ve 42 günlük broylerlerin ileum dokusunda mast hücrelerinin sayısı ve heterojenitesi çalışıldı. Mast hücreleri metakromazik olarak toluidin mavisi ile tüm gruplarda boyandı. İleumun tüm katmanlarında, özellikle lamina propria ve submukozada mast hücreleri görüldü. Ayrıca kan damarların çevresinde ve tunika muskularis tabakasındaki düz kas hücreleri arasında gözlendi. Broyler ileumda, her iki mast hücresi alt tipi görüldü: mavi renkli AB (+) ve kırmızı-pembe renkli SO (+) mast hücreleri. Tüm yaş gruplarında AB (+) mast hücreleri görülürken, 0. yaş grubunda hiç SO (+) mast hücresi bulunmadı. SO (+) mast hücreleri ilk olarak yumurtadan çıktıktan sonraki yedinci günde ileum dokusunda tespit edildi. Sonuç olarak, mast hücre sayısının yaşla birlikte arttığı bulundu ki bu istatistiksel olarak anlamlıydı.
