However, there is much controversy about the importance of mast cells in skin wound repair. Few studies have demonstrated the presence of mast cells in skin wound repair in middle-aged and senescent individuals. The mast cells are resident cells in the skin and participate in the inflammatory process and wound repair response. It is known that there are major changes in the immune system with aging, including in the skin. In this work, we evaluated the density and maturation of mast cells (mature, intermediate and immature) at the edges of skin wounds in young, middle-aged and senescent mice by toluidine blue and alcianine-safranin blue staining. We found that there is a significant decrease in mast cells in senescent mice. There is a predominance of immature mast cells at all ages 5 days after injury. But the data are intriguing, as in senescent mice there are fewer mature mast cells. Further studies should be carried out to understand the role of mast cells during aging.Page(s): 905-910ISSN: 0975-1009 (Online); 0019-5189 (Print)Appears in Collections:IJEB Vol.61(12) [December 2023]
